Complete the code in python to solve this programming problem:
Description: Monocarp plays "Rage of Empires II: Definitive Edition" — a strategic computer game. Right now he's planning to attack his opponent in the game, but Monocarp's forces cannot enter the opponent's territory since the opponent has built a wall.The wall consists of $$$n$$$ sections, aligned in a row. The $$$i$$$-th section initially has durability $$$a_i$$$. If durability of some section becomes $$$0$$$ or less, this section is considered broken.To attack the opponent, Monocarp needs to break at least two sections of the wall (any two sections: possibly adjacent, possibly not). To do this, he plans to use an onager — a special siege weapon. The onager can be used to shoot any section of the wall; the shot deals $$$2$$$ damage to the target section and $$$1$$$ damage to adjacent sections. In other words, if the onager shoots at the section $$$x$$$, then the durability of the section $$$x$$$ decreases by $$$2$$$, and the durability of the sections $$$x - 1$$$ and $$$x + 1$$$ (if they exist) decreases by $$$1$$$ each. Monocarp can shoot at any sections any number of times, he can even shoot at broken sections.Monocarp wants to calculate the minimum number of onager shots needed to break at least two sections. Help him!
Input Specification: The first line contains one integer $$$n$$$ ($$$2 \le n \le 2 \cdot 10^5$$$) — the number of sections. The second line contains the sequence of integers $$$a_1, a_2, \dots, a_n$$$ ($$$1 \le a_i \le 10^6$$$), where $$$a_i$$$ is the initial durability of the $$$i$$$-th section.
Output Specification: Print one integer — the minimum number of onager shots needed to break at least two sections of the wall.
Notes: NoteIn the first example, it is possible to break the $$$2$$$-nd and the $$$4$$$-th section in $$$10$$$ shots, for example, by shooting the third section $$$10$$$ times. After that, the durabilities become $$$[20, 0, 10, 0, 20]$$$. Another way of doing it is firing $$$5$$$ shots at the $$$2$$$-nd section, and another $$$5$$$ shots at the $$$4$$$-th section. After that, the durabilities become $$$[15, 0, 20, 0, 15]$$$.In the second example, it is enough to shoot the $$$2$$$-nd section once. Then the $$$1$$$-st and the $$$3$$$-rd section will be broken.In the third example, it is enough to shoot the $$$2$$$-nd section twice (then the durabilities become $$$[5, 2, 4, 8, 5, 8]$$$), and then shoot the $$$3$$$-rd section twice (then the durabilities become $$$[5, 0, 0, 6, 5, 8]$$$). So, four shots are enough to break the $$$2$$$-nd and the $$$3$$$-rd section.

Description: There is an array $$$a$$$ of length $$$n$$$. You may perform the following operation any number of times: Choose two indices $$$l$$$ and $$$r$$$ where $$$1 \le l < r \le n$$$ and $$$a_l = a_r$$$. Then, set $$$a[l \ldots r] = [a_{l+1}, a_{l+2}, \ldots, a_r, a_l]$$$. You are also given another array $$$b$$$ of length $$$n$$$ which is a permutation of $$$a$$$. Determine whether it is possible to transform array $$$a$$$ into an array $$$b$$$ using the above operation some number of times.
Input Specification: Each test contains multiple test cases. The first line contains a single integer $$$t$$$ ($$$1 \leq t \leq 10^4$$$) — the number of test cases. The description of the test cases follows. The first line of each test case contains an integer $$$n$$$ ($$$1 \le n \le 2 \cdot 10 ^ 5$$$) — the length of array $$$a$$$ and $$$b$$$. The second line of each test case contains $$$n$$$ integers $$$a_1, a_2, \ldots, a_n$$$ ($$$1 \le a_i \le n$$$) — elements of the array $$$a$$$. The third line of each test case contains $$$n$$$ integers $$$b_1, b_2, \ldots, b_n$$$ ($$$1 \le b_i \le n$$$) — elements of the array $$$b$$$. It is guaranteed that $$$b$$$ is a permutation of $$$a$$$. It is guaranteed that the sum of $$$n$$$ over all test cases does not exceed $$$2 \cdot 10 ^ 5$$$
Output Specification: For each test case, print "YES" (without quotes) if it is possible to transform array $$$a$$$ to $$$b$$$, and "NO" (without quotes) otherwise. You can output "YES" and "NO" in any case (for example, strings "yEs", "yes" and "Yes" will be recognized as a positive response).
Notes: NoteIn the first test case, we can choose $$$l=2$$$ and $$$r=5$$$ to form $$$[1, 3, 3, 2, 2]$$$.In the second test case, we can choose $$$l=2$$$ and $$$r=4$$$ to form $$$[1, 4, 2, 2, 1]$$$. Then, we can choose $$$l=1$$$ and $$$r=5$$$ to form $$$[4, 2, 2, 1, 1]$$$.In the third test case, it can be proven that it is not possible to transform array $$$a$$$ to $$$b$$$ using the operation.

You may perform the following operation any number of times: Choose two indices $$$l$$$ and $$$r$$$ where $$$1 \le l < r \le n$$$ and $$$a_l = a_r$$$. Then, set $$$a[l \ldots r] = [a_{l+1}, a_{l+2}, \ldots, a_r, a_l]$$$. You are also given another array $$$b$$$ of length $$$n$$$ which is a permutation of $$$a$$$. Determine whether it is possible to transform array $$$a$$$ into an array $$$b$$$ using the above operation some number of times.
Input Specification: Each test contains multiple test cases. The first line contains a single integer $$$t$$$ ($$$1 \leq t \leq 10^4$$$) — the number of test cases. The description of the test cases follows. The first line of each test case contains an integer $$$n$$$ ($$$1 \le n \le 2 \cdot 10 ^ 5$$$) — the length of array $$$a$$$ and $$$b$$$. The second line of each test case contains $$$n$$$ integers $$$a_1, a_2, \ldots, a_n$$$ ($$$1 \le a_i \le n$$$) — elements of the array $$$a$$$. The third line of each test case contains $$$n$$$ integers $$$b_1, b_2, \ldots, b_n$$$ ($$$1 \le b_i \le n$$$) — elements of the array $$$b$$$. It is guaranteed that $$$b$$$ is a permutation of $$$a$$$. It is guaranteed that the sum of $$$n$$$ over all test cases does not exceed $$$2 \cdot 10 ^ 5$$$
Output Specification: For each test case, print "YES" (without quotes) if it is possible to transform array $$$a$$$ to $$$b$$$, and "NO" (without quotes) otherwise. You can output "YES" and "NO" in any case (for example, strings "yEs", "yes" and "Yes" will be recognized as a positive response).
Notes: NoteIn the first test case, we can choose $$$l=2$$$ and $$$r=5$$$ to form $$$[1, 3, 3, 2, 2]$$$.In the second test case, we can choose $$$l=2$$$ and $$$r=4$$$ to form $$$[1, 4, 2, 2, 1]$$$. Then, we can choose $$$l=1$$$ and $$$r=5$$$ to form $$$[4, 2, 2, 1, 1]$$$.In the third test case, it can be proven that it is not possible to transform array $$$a$$$ to $$$b$$$ using the operation.

In the $$$i$$$-th query, you are given two indices $$$l$$$ and $$$r$$$ such that $$$1 \le l \le r \le n$$$. Let $$$s=a[l,r]$$$. You are allowed to do the following operation on $$$s$$$: Choose two indices $$$x$$$ and $$$y$$$ such that $$$1 \le x \le y \le |s|$$$. Let $$$t$$$ be the substring $$$t = s[x, y]$$$. Then for all $$$1 \le i \le |t| - 1$$$, the condition $$$t_i \neq t_{i+1}$$$ has to hold. Note that $$$x = y$$$ is always a valid substring. Delete the substring $$$s[x, y]$$$ from $$$s$$$.

Complete the code in python to solve this programming problem:
Description: You have a binary string $$$a$$$ of length $$$n$$$ consisting only of digits $$$0$$$ and $$$1$$$. You are given $$$q$$$ queries. In the $$$i$$$-th query, you are given two indices $$$l$$$ and $$$r$$$ such that $$$1 \le l \le r \le n$$$. Let $$$s=a[l,r]$$$. You are allowed to do the following operation on $$$s$$$: Choose two indices $$$x$$$ and $$$y$$$ such that $$$1 \le x \le y \le |s|$$$. Let $$$t$$$ be the substring $$$t = s[x, y]$$$. Then for all $$$1 \le i \le |t| - 1$$$, the condition $$$t_i \neq t_{i+1}$$$ has to hold. Note that $$$x = y$$$ is always a valid substring. Delete the substring $$$s[x, y]$$$ from $$$s$$$. For each of the $$$q$$$ queries, find the minimum number of operations needed to make $$$s$$$ an empty string.Note that for a string $$$s$$$, $$$s[l,r]$$$ denotes the subsegment $$$s_l,s_{l+1},\ldots,s_r$$$.
Input Specification: The first line contains two integers $$$n$$$ and $$$q$$$ ($$$1 \le n, q \le 2 \cdot 10 ^ 5$$$) — the length of the binary string $$$a$$$ and the number of queries respectively. The second line contains a binary string $$$a$$$ of length $$$n$$$ ($$$a_i \in \{0, 1\}$$$). Each of the next $$$q$$$ lines contains two integers $$$l$$$ and $$$r$$$ ($$$1 \le l \le r \le n$$$) — representing the substring of each query.
Output Specification: Print $$$q$$$ lines, the $$$i$$$-th line representing the minimum number of operations needed for the $$$i$$$-th query.
Notes: NoteIn the first test case, The substring is $$$\texttt{101}$$$, so we can do one operation to make the substring empty. The substring is $$$\texttt{11011}$$$, so we can do one operation on $$$s[2, 4]$$$ to make $$$\texttt{11}$$$, then use two more operations to make the substring empty. The substring is $$$\texttt{011}$$$, so we can do one operation on $$$s[1, 2]$$$ to make $$$\texttt{1}$$$, then use one more operation to make the substring empty.

Complete the code in python to solve this programming problem:
Description: There is a grid with $$$r$$$ rows and $$$c$$$ columns, where the square on the $$$i$$$-th row and $$$j$$$-th column has an integer $$$a_{i, j}$$$ written on it. Initially, all elements are set to $$$0$$$. We are allowed to do the following operation: Choose indices $$$1 \le i \le r$$$ and $$$1 \le j \le c$$$, then replace all values on the same row or column as $$$(i, j)$$$ with the value xor $$$1$$$. In other words, for all $$$a_{x, y}$$$ where $$$x=i$$$ or $$$y=j$$$ or both, replace $$$a_{x, y}$$$ with $$$a_{x, y}$$$ xor $$$1$$$. You want to form grid $$$b$$$ by doing the above operations a finite number of times. However, some elements of $$$b$$$ are missing and are replaced with '?' instead.Let $$$k$$$ be the number of '?' characters. Among all the $$$2^k$$$ ways of filling up the grid $$$b$$$ by replacing each '?' with '0' or '1', count the number of grids, that can be formed by doing the above operation a finite number of times, starting from the grid filled with $$$0$$$. As this number can be large, output it modulo $$$998244353$$$.
Input Specification: The first line contains two integers $$$r$$$ and $$$c$$$ ($$$1 \le r, c \le 2000$$$) — the number of rows and columns of the grid respectively. The $$$i$$$-th of the next $$$r$$$ lines contain $$$c$$$ characters $$$b_{i, 1}, b_{i, 2}, \ldots, b_{i, c}$$$ ($$$b_{i, j} \in \{0, 1, ?\}$$$).
Output Specification: Print a single integer representing the number of ways to fill up grid $$$b$$$ modulo $$$998244353$$$.
Notes: NoteIn the first test case, the only way to fill in the $$$\texttt{?}$$$s is to fill it in as such: 010111010 This can be accomplished by doing a single operation by choosing $$$(i,j)=(2,2)$$$.In the second test case, it can be shown that there is no sequence of operations that can produce that grid.

Description: This is the hard version of the problem. The only difference between the two versions is that the harder version asks additionally for a minimum number of subsegments.Tokitsukaze has a binary string $$$s$$$ of length $$$n$$$, consisting only of zeros and ones, $$$n$$$ is even.Now Tokitsukaze divides $$$s$$$ into the minimum number of contiguous subsegments, and for each subsegment, all bits in each subsegment are the same. After that, $$$s$$$ is considered good if the lengths of all subsegments are even.For example, if $$$s$$$ is "11001111", it will be divided into "11", "00" and "1111". Their lengths are $$$2$$$, $$$2$$$, $$$4$$$ respectively, which are all even numbers, so "11001111" is good. Another example, if $$$s$$$ is "1110011000", it will be divided into "111", "00", "11" and "000", and their lengths are $$$3$$$, $$$2$$$, $$$2$$$, $$$3$$$. Obviously, "1110011000" is not good.Tokitsukaze wants to make $$$s$$$ good by changing the values of some positions in $$$s$$$. Specifically, she can perform the operation any number of times: change the value of $$$s_i$$$ to '0' or '1' ($$$1 \leq i \leq n$$$). Can you tell her the minimum number of operations to make $$$s$$$ good? Meanwhile, she also wants to know the minimum number of subsegments that $$$s$$$ can be divided into among all solutions with the minimum number of operations.
Input Specification: The first contains a single positive integer $$$t$$$ ($$$1 \leq t \leq 10\,000$$$) — the number of test cases. For each test case, the first line contains a single integer $$$n$$$ ($$$2 \leq n \leq 2 \cdot 10^5$$$) — the length of $$$s$$$, it is guaranteed that $$$n$$$ is even. The second line contains a binary string $$$s$$$ of length $$$n$$$, consisting only of zeros and ones. It is guaranteed that the sum of $$$n$$$ over all test cases does not exceed $$$2 \cdot 10^5$$$.
Output Specification: For each test case, print a single line with two integers — the minimum number of operations to make $$$s$$$ good, and the minimum number of subsegments that $$$s$$$ can be divided into among all solutions with the minimum number of operations.
Notes: NoteIn the first test case, one of the ways to make $$$s$$$ good is the following.Change $$$s_3$$$, $$$s_6$$$ and $$$s_7$$$ to '0', after that $$$s$$$ becomes "1100000000", it can be divided into "11" and "00000000", which lengths are $$$2$$$ and $$$8$$$ respectively, the number of subsegments of it is $$$2$$$. There are other ways to operate $$$3$$$ times to make $$$s$$$ good, such as "1111110000", "1100001100", "1111001100", the number of subsegments of them are $$$2$$$, $$$4$$$, $$$4$$$ respectively. It's easy to find that the minimum number of subsegments among all solutions with the minimum number of operations is $$$2$$$.In the second, third and fourth test cases, $$$s$$$ is good initially, so no operation is required.

For each test case, the first line contains a single integer $$$n$$$ ($$$2 \leq n \leq 2 \cdot 10^5$$$) — the length of $$$s$$$, it is guaranteed that $$$n$$$ is even. The second line contains a binary string $$$s$$$ of length $$$n$$$, consisting only of zeros and ones. It is guaranteed that the sum of $$$n$$$ over all test cases does not exceed $$$2 \cdot 10^5$$$.
Output Specification: For each test case, print a single line with two integers — the minimum number of operations to make $$$s$$$ good, and the minimum number of subsegments that $$$s$$$ can be divided into among all solutions with the minimum number of operations.
Notes: NoteIn the first test case, one of the ways to make $$$s$$$ good is the following.Change $$$s_3$$$, $$$s_6$$$ and $$$s_7$$$ to '0', after that $$$s$$$ becomes "1100000000", it can be divided into "11" and "00000000", which lengths are $$$2$$$ and $$$8$$$ respectively, the number of subsegments of it is $$$2$$$. There are other ways to operate $$$3$$$ times to make $$$s$$$ good, such as "1111110000", "1100001100", "1111001100", the number of subsegments of them are $$$2$$$, $$$4$$$, $$$4$$$ respectively. It's easy to find that the minimum number of subsegments among all solutions with the minimum number of operations is $$$2$$$.In the second, third and fourth test cases, $$$s$$$ is good initially, so no operation is required.

Description: This is the hard version of the problem. The only difference between the two versions is that the harder version asks additionally for a minimum number of subsegments.Tokitsukaze has a binary string $$$s$$$ of length $$$n$$$, consisting only of zeros and ones, $$$n$$$ is even.Now Tokitsukaze divides $$$s$$$ into the minimum number of contiguous subsegments, and for each subsegment, all bits in each subsegment are the same. After that, $$$s$$$ is considered good if the lengths of all subsegments are even.For example, if $$$s$$$ is "11001111", it will be divided into "11", "00" and "1111". Their lengths are $$$2$$$, $$$2$$$, $$$4$$$ respectively, which are all even numbers, so "11001111" is good. Another example, if $$$s$$$ is "1110011000", it will be divided into "111", "00", "11" and "000", and their lengths are $$$3$$$, $$$2$$$, $$$2$$$, $$$3$$$.

Obviously, "1110011000" is not good.Tokitsukaze wants to make $$$s$$$ good by changing the values of some positions in $$$s$$$. Specifically, she can perform the operation any number of times: change the value of $$$s_i$$$ to '0' or '1'($$$1 \leq i \leq n$$$). Can you tell her the minimum number of operations to make $$$s$$$ good?
Input Specification: The first contains a single positive integer $$$t$$$ ($$$1 \leq t \leq 10\,000$$$) — the number of test cases. For each test case, the first line contains a single integer $$$n$$$ ($$$2 \leq n \leq 2 \cdot 10^5$$$) — the length of $$$s$$$, it is guaranteed that $$$n$$$ is even. The second line contains a binary string $$$s$$$ of length $$$n$$$, consisting only of zeros and ones. It is guaranteed that the sum of $$$n$$$ over all test cases does not exceed $$$2 \cdot 10^5$$$.
Output Specification: For each test case, print a single line with one integer — the minimum number of operations to make $$$s$$$ good.
Notes: NoteIn the first test case, one of the ways to make $$$s$$$ good is the following.Change $$$s_3$$$, $$$s_6$$$ and $$$s_7$$$ to '0', after that $$$s$$$ becomes "1100000000", it can be divided into "11" and "00000000", which lengths are $$$2$$$ and $$$8$$$ respectively. There are other ways to operate $$$3$$$ times to make $$$s$$$ good, such as "1111110000", "1100001100", "1111001100".In the second, third and fourth test cases, $$$s$$$ is good initially, so no operation is required.

Description: Tokitsukaze has a sequence $$$a$$$ of length $$$n$$$. For each operation, she selects two numbers $$$a_i$$$ and $$$a_j$$$ ($$$i \ne j$$$; $$$1 \leq i,j \leq n$$$). If $$$a_i = a_j$$$, change one of them to $$$0$$$. Otherwise change both of them to $$$\min(a_i, a_j)$$$. Tokitsukaze wants to know the minimum number of operations to change all numbers in the sequence to $$$0$$$. It can be proved that the answer always exists.
Input Specification: The first line contains a single positive integer $$$t$$$ ($$$1 \leq t \leq 1000$$$) — the number of test cases. For each test case, the first line contains a single integer $$$n$$$ ($$$2 \leq n \leq 100$$$) — the length of the sequence $$$a$$$. The second line contains $$$n$$$ integers $$$a_1, a_2, \ldots, a_n$$$ ($$$0 \leq a_i \leq 100$$$) — the sequence $$$a$$$.
Output Specification: For each test case, print a single integer — the minimum number of operations to change all numbers in the sequence to $$$0$$$.
Notes: NoteIn the first test case, one of the possible ways to change all numbers in the sequence to $$$0$$$:In the $$$1$$$-st operation, $$$a_1 < a_2$$$, after the operation, $$$a_2 = a_1 = 1$$$. Now the sequence $$$a$$$ is $$$[1,1,3]$$$.In the $$$2$$$-nd operation, $$$a_1 = a_2 = 1$$$, after the operation, $$$a_1 = 0$$$. Now the sequence $$$a$$$ is $$$[0,1,3]$$$.In the $$$3$$$-rd operation, $$$a_1 < a_2$$$, after the operation, $$$a_2 = 0$$$. Now the sequence $$$a$$$ is $$$[0,0,3]$$$.In the $$$4$$$-th operation, $$$a_2 < a_3$$$, after the operation, $$$a_3 = 0$$$. Now the sequence $$$a$$$ is $$$[0,0,0]$$$.So the minimum number of operations is $$$4$$$.

Now the sequence $$$a$$$ is $$$[0,1,3]$$$.In the $$$3$$$-rd operation, $$$a_1 < a_2$$$, after the operation, $$$a_2 = 0$$$. Now the sequence $$$a$$$ is $$$[0,0,3]$$$.In the $$$4$$$-th operation, $$$a_2 < a_3$$$, after the operation, $$$a_3 = 0$$$. Now the sequence $$$a$$$ is $$$[0,0,0]$$$.So the minimum number of operations is $$$4$$$.

Complete the code in python to solve this programming problem:
Description: You are given an array $$$a$$$ consisting of $$$n$$$ positive integers.You are allowed to perform this operation any number of times (possibly, zero): choose an index $$$i$$$ ($$$2 \le i \le n$$$), and change $$$a_i$$$ to $$$a_i - a_{i-1}$$$. Is it possible to make $$$a_i=0$$$ for all $$$2\le i\le n$$$?
Input Specification: The input consists of multiple test cases. The first line contains a single integer $$$t$$$ ($$$1\le t\le 100$$$) — the number of test cases. The description of the test cases follows. The first line contains one integer $$$n$$$ ($$$2 \le n \le 100$$$) — the length of array $$$a$$$. The second line contains $$$n$$$ integers $$$a_1,a_2,\ldots,a_n$$$ ($$$1 \le a_i \le 10^9$$$).
Output Specification: For each test case, print "YES" (without quotes), if it is possible to change $$$a_i$$$ to $$$0$$$ for all $$$2 \le i \le n$$$, and "NO" (without quotes) otherwise. You can print letters in any case (upper or lower).
Notes: NoteIn the first test case, the initial array is $$$[5,10]$$$. You can perform $$$2$$$ operations to reach the goal: Choose $$$i=2$$$, and the array becomes $$$[5,5]$$$. Choose $$$i=2$$$, and the array becomes $$$[5,0]$$$. In the second test case, the initial array is $$$[1,2,3]$$$. You can perform $$$4$$$ operations to reach the goal: Choose $$$i=3$$$, and the array becomes $$$[1,2,1]$$$. Choose $$$i=2$$$, and the array becomes $$$[1,1,1]$$$. Choose $$$i=3$$$, and the array becomes $$$[1,1,0]$$$. Choose $$$i=2$$$, and the array becomes $$$[1,0,0]$$$. In the third test case, you can choose indices in the order $$$4$$$, $$$3$$$, $$$2$$$.

Description: There is a chip on the coordinate line. Initially, the chip is located at the point $$$0$$$. You can perform any number of moves; each move increases the coordinate of the chip by some positive integer (which is called the length of the move). The length of the first move you make should be divisible by $$$k$$$, the length of the second move — by $$$k+1$$$, the third — by $$$k+2$$$, and so on.For example, if $$$k=2$$$, then the sequence of moves may look like this: $$$0 \rightarrow 4 \rightarrow 7 \rightarrow 19 \rightarrow 44$$$, because $$$4 - 0 = 4$$$ is divisible by $$$2 = k$$$, $$$7 - 4 = 3$$$ is divisible by $$$3 = k + 1$$$, $$$19 - 7 = 12$$$ is divisible by $$$4 = k + 2$$$, $$$44 - 19 = 25$$$ is divisible by $$$5 = k + 3$$$.You are given two positive integers $$$n$$$ and $$$k$$$. Your task is to count the number of ways to reach the point $$$x$$$, starting from $$$0$$$, for every $$$x \in [1, n]$$$. The number of ways can be very large, so print it modulo $$$998244353$$$. Two ways are considered different if they differ as sets of visited positions.
Input Specification: The first (and only) line of the input contains two integers $$$n$$$ and $$$k$$$ ($$$1 \le k \le n \le 2 \cdot 10^5$$$).

Complete the code in python to solve this programming problem:
Description: There is a chip on the coordinate line. Initially, the chip is located at the point $$$0$$$. You can perform any number of moves; each move increases the coordinate of the chip by some positive integer (which is called the length of the move). The length of the first move you make should be divisible by $$$k$$$, the length of the second move — by $$$k+1$$$, the third — by $$$k+2$$$, and so on.For example, if $$$k=2$$$, then the sequence of moves may look like this: $$$0 \rightarrow 4 \rightarrow 7 \rightarrow 19 \rightarrow 44$$$, because $$$4 - 0 = 4$$$ is divisible by $$$2 = k$$$, $$$7 - 4 = 3$$$ is divisible by $$$3 = k + 1$$$, $$$19 - 7 = 12$$$ is divisible by $$$4 = k + 2$$$, $$$44 - 19 = 25$$$ is divisible by $$$5 = k + 3$$$.You are given two positive integers $$$n$$$ and $$$k$$$. Your task is to count the number of ways to reach the point $$$x$$$, starting from $$$0$$$, for every $$$x \in [1, n]$$$. The number of ways can be very large, so print it modulo $$$998244353$$$. Two ways are considered different if they differ as sets of visited positions.
Input Specification: The first (and only) line of the input contains two integers $$$n$$$ and $$$k$$$ ($$$1 \le k \le n \le 2 \cdot 10^5$$$).
Output Specification: Print $$$n$$$ integers — the number of ways to reach the point $$$x$$$, starting from $$$0$$$, for every $$$x \in [1, n]$$$, taken modulo $$$998244353$$$.

Complete the code in python to solve this programming problem:
Description: There is a grid, consisting of $$$2$$$ rows and $$$m$$$ columns. The rows are numbered from $$$1$$$ to $$$2$$$ from top to bottom. The columns are numbered from $$$1$$$ to $$$m$$$ from left to right.The robot starts in a cell $$$(1, 1)$$$. In one second, it can perform either of two actions: move into a cell adjacent by a side: up, right, down or left; remain in the same cell. The robot is not allowed to move outside the grid.Initially, all cells, except for the cell $$$(1, 1)$$$, are locked. Each cell $$$(i, j)$$$ contains a value $$$a_{i,j}$$$ — the moment that this cell gets unlocked. The robot can only move into a cell $$$(i, j)$$$ if at least $$$a_{i,j}$$$ seconds have passed before the move.The robot should visit all cells without entering any cell twice or more (cell $$$(1, 1)$$$ is considered entered at the start). It can finish in any cell.What is the fastest the robot can achieve that?
Input Specification: The first line contains a single integer $$$t$$$ ($$$1 \le t \le 10^4$$$) — the number of testcases. The first line of each testcase contains a single integer $$$m$$$ ($$$2 \le m \le 2 \cdot 10^5$$$) — the number of columns of the grid. The $$$i$$$-th of the next $$$2$$$ lines contains $$$m$$$ integers $$$a_{i,1}, a_{i,2}, \dots, a_{i,m}$$$ ($$$0 \le a_{i,j} \le 10^9$$$) — the moment of time each cell gets unlocked. $$$a_{1,1} = 0$$$. If $$$a_{i,j} = 0$$$, then cell $$$(i, j)$$$ is unlocked from the start. The sum of $$$m$$$ over all testcases doesn't exceed $$$2 \cdot 10^5$$$.
Output Specification: For each testcase, print a single integer — the minimum amount of seconds that the robot can take to visit all cells without entering any cell twice or more.

Complete the code in python to solve this programming problem:
Description: There is a grid, consisting of $$$2$$$ rows and $$$m$$$ columns. The rows are numbered from $$$1$$$ to $$$2$$$ from top to bottom. The columns are numbered from $$$1$$$ to $$$m$$$ from left to right.The robot starts in a cell $$$(1, 1)$$$. In one second, it can perform either of two actions: move into a cell adjacent by a side: up, right, down or left; remain in the same cell. The robot is not allowed to move outside the grid.Initially, all cells, except for the cell $$$(1, 1)$$$, are locked. Each cell $$$(i, j)$$$ contains a value $$$a_{i,j}$$$ — the moment that this cell gets unlocked. The robot can only move into a cell $$$(i, j)$$$ if at least $$$a_{i,j}$$$ seconds have passed before the move.The robot should visit all cells without entering any cell twice or more (cell $$$(1, 1)$$$ is considered entered at the start). It can finish in any cell.What is the fastest the robot can achieve that?
Input Specification: The first line contains a single integer $$$t$$$ ($$$1 \le t \le 10^4$$$) — the number of testcases. The first line of each testcase contains a single integer $$$m$$$ ($$$2 \le m \le 2 \cdot 10^5$$$) — the number of columns of the grid. The $$$i$$$-th of the next $$$2$$$ lines contains $$$m$$$ integers $$$a_{i,1}, a_{i,2}, \dots, a_{i,m}$$$ ($$$0 \le a_{i,j} \le 10^9$$$) — the moment of time each cell gets unlocked. $$$a_{1,1} = 0$$$. If $$$a_{i,j} = 0$$$, then cell $$$(i, j)$$$ is unlocked from the start. The sum of $$$m$$$ over all testcases doesn't exceed $$$2 \cdot 10^5$$$.
Output Specification: For each testcase, print a single integer — the minimum amount of seconds that the robot can take to visit all cells without entering any cell twice or more.

Description: You are given an array of length $$$2^n$$$. The elements of the array are numbered from $$$1$$$ to $$$2^n$$$.You have to process $$$q$$$ queries to this array. In the $$$i$$$-th query, you will be given an integer $$$k$$$ ($$$0 \le k \le n-1$$$). To process the query, you should do the following: for every $$$i \in [1, 2^n-2^k]$$$ in ascending order, do the following: if the $$$i$$$-th element was already swapped with some other element during this query, skip it; otherwise, swap $$$a_i$$$ and $$$a_{i+2^k}$$$; after that, print the maximum sum over all contiguous subsegments of the array (including the empty subsegment). For example, if the array $$$a$$$ is $$$[-3, 5, -3, 2, 8, -20, 6, -1]$$$, and $$$k = 1$$$, the query is processed as follows: the $$$1$$$-st element wasn't swapped yet, so we swap it with the $$$3$$$-rd element; the $$$2$$$-nd element wasn't swapped yet, so we swap it with the $$$4$$$-th element; the $$$3$$$-rd element was swapped already; the $$$4$$$-th element was swapped already; the $$$5$$$-th element wasn't swapped yet, so we swap it with the $$$7$$$-th element; the $$$6$$$-th element wasn't swapped yet, so we swap it with the $$$8$$$-th element. So, the array becomes $$$[-3, 2, -3, 5, 6, -1, 8, -20]$$$. The subsegment with the maximum sum is $$$[5, 6, -1, 8]$$$, and the answer to the query is $$$18$$$.Note that the queries actually change the array, i. e. after a query is performed, the array does not return to its original state, and the next query will be applied to the modified array.
Input Specification: The first line contains one integer $$$n$$$ ($$$1 \le n \le 18$$$). The second line contains $$$2^n$$$ integers $$$a_1, a_2, \dots, a_{2^n}$$$ ($$$-10^9 \le a_i \le 10^9$$$). The third line contains one integer $$$q$$$ ($$$1 \le q \le 2 \cdot 10^5$$$). Then $$$q$$$ lines follow, the $$$i$$$-th of them contains one integer $$$k$$$ ($$$0 \le k \le n-1$$$) describing the $$$i$$$-th query.
Output Specification: For each query, print one integer — the maximum sum over all contiguous subsegments of the array (including the empty subsegment) after processing the query.
Notes: NoteTransformation of the array in the example: $$$[-3, 5, -3, 2, 8, -20, 6, -1] \rightarrow [-3, 2, -3, 5, 6, -1, 8, -20] \rightarrow [2, -3, 5, -3, -1, 6, -20, 8] \rightarrow [5, -3, 2, -3, -20, 8, -1, 6]$$$.

Complete the code in python to solve this programming problem:
Description: Consider a hallway, which can be represented as the matrix with $$$2$$$ rows and $$$n$$$ columns. Let's denote the cell on the intersection of the $$$i$$$-th row and the $$$j$$$-th column as $$$(i, j)$$$. The distance between the cells $$$(i_1, j_1)$$$ and $$$(i_2, j_2)$$$ is $$$|i_1 - i_2| + |j_1 - j_2|$$$.There is a cleaning robot in the cell $$$(1, 1)$$$. Some cells of the hallway are clean, other cells are dirty (the cell with the robot is clean). You want to clean the hallway, so you are going to launch the robot to do this.After the robot is launched, it works as follows. While at least one cell is dirty, the robot chooses the closest (to its current cell) cell among those which are dirty, moves there and cleans it (so the cell is no longer dirty). After cleaning a cell, the robot again finds the closest dirty cell to its current cell, and so on. This process repeats until the whole hallway is clean.However, there is a critical bug in the robot's program. If at some moment, there are multiple closest (to the robot's current position) dirty cells, the robot malfunctions.You want to clean the hallway in such a way that the robot doesn't malfunction. Before launching the robot, you can clean some (possibly zero) of the dirty cells yourself. However, you don't want to do too much dirty work yourself while you have this nice, smart (yet buggy) robot to do this. Note that you cannot make a clean cell dirty.Calculate the maximum possible number of cells you can leave dirty before launching the robot, so that it doesn't malfunction.
Input Specification: The first line contains one integer $$$n$$$ ($$$2 \le n \le 2 \cdot 10^5$$$) — the number of columns in the hallway. Then two lines follow, denoting the $$$1$$$-st and the $$$2$$$-nd row of the hallway. These lines contain $$$n$$$ characters each, where 0 denotes a clean cell and 1 denotes a dirty cell. The starting cell of the robot $$$(1, 1)$$$ is clean.
Output Specification: Print one integer — the maximum possible number of cells you can leave dirty before launching the robot, so that it doesn't malfunction.
Notes: NoteIn the first example, you can clean the cell $$$(1, 2)$$$, so the path of the robot is $$$(1, 1) \rightarrow (2, 1) \rightarrow (2, 2)$$$.In the second example, you can leave the hallway as it is, so the path of the robot is $$$(1, 1) \rightarrow (1, 2) \rightarrow (2, 2)$$$.In the third example, you can clean the cell $$$(1, 2)$$$, so the path of the robot is $$$(1, 1) \rightarrow (2, 1) \rightarrow (2, 3) \rightarrow (2, 4) \rightarrow (1, 4)$$$.In the fourth example, the hallway is already clean. Maybe you have launched the robot earlier?

Complete the code in python to solve this programming problem:
Description: Consider a hallway, which can be represented as the matrix with $$$2$$$ rows and $$$n$$$ columns. Let's denote the cell on the intersection of the $$$i$$$-th row and the $$$j$$$-th column as $$$(i, j)$$$. The distance between the cells $$$(i_1, j_1)$$$ and $$$(i_2, j_2)$$$ is $$$|i_1 - i_2| + |j_1 - j_2|$$$.There is a cleaning robot in the cell $$$(1, 1)$$$. Some cells of the hallway are clean, other cells are dirty (the cell with the robot is clean). You want to clean the hallway, so you are going to launch the robot to do this.After the robot is launched, it works as follows. While at least one cell is dirty, the robot chooses the closest (to its current cell) cell among those which are dirty, moves there and cleans it (so the cell is no longer dirty). After cleaning a cell, the robot again finds the closest dirty cell to its current cell, and so on. This process repeats until the whole hallway is clean.However, there is a critical bug in the robot's program. If at some moment, there are multiple closest (to the robot's current position) dirty cells, the robot malfunctions.You want to clean the hallway in such a way that the robot doesn't malfunction. Before launching the robot, you can clean some (possibly zero) of the dirty cells yourself. However, you don't want to do too much dirty work yourself while you have this nice, smart (yet buggy) robot to do this. Note that you cannot make a clean cell dirty.Calculate the maximum possible number of cells you can leave dirty before launching the robot, so that it doesn't malfunction.
Input Specification: The first line contains one integer $$$n$$$ ($$$2 \le n \le 2 \cdot 10^5$$$) — the number of columns in the hallway. Then two lines follow, denoting the $$$1$$$-st and the $$$2$$$-nd row of the hallway. These lines contain $$$n$$$ characters each, where 0 denotes a clean cell and 1 denotes a dirty cell. The starting cell of the robot $$$(1, 1)$$$ is clean.
Output Specification: Print one integer — the maximum possible number of cells you can leave dirty before launching the robot, so that it doesn't malfunction.
Notes: NoteIn the first example, you can clean the cell $$$(1, 2)$$$, so the path of the robot is $$$(1, 1) \rightarrow (2, 1) \rightarrow (2, 2)$$$.In the second example, you can leave the hallway as it is, so the path of the robot is $$$(1, 1) \rightarrow (1, 2) \rightarrow (2, 2)$$$.In the third example, you can clean the cell $$$(1, 2)$$$, so the path of the robot is $$$(1, 1) \rightarrow (2, 1) \rightarrow (2, 3) \rightarrow (2, 4) \rightarrow (1, 4)$$$.In the fourth example, the hallway is already clean. Maybe you have launched the robot earlier?

Complete the code in python to solve this programming problem:
Description: Vasya has a grid with $$$2$$$ rows and $$$n$$$ columns. He colours each cell red, green, or blue.Vasya is colourblind and can't distinguish green from blue. Determine if Vasya will consider the two rows of the grid to be coloured the same.
Input Specification: The input consists of multiple test cases. The first line contains an integer $$$t$$$ ($$$1 \leq t \leq 100$$$) — the number of test cases. The description of the test cases follows. The first line of each test case contains an integer $$$n$$$ ($$$1 \leq n \leq 100$$$) — the number of columns of the grid. The following two lines each contain a string consisting of $$$n$$$ characters, each of which is either R, G, or B, representing a red, green, or blue cell, respectively — the description of the grid.
Output Specification: For each test case, output "YES" if Vasya considers the grid's two rows to be identical, and "NO" otherwise. You can output the answer in any case (for example, the strings "yEs", "yes", "Yes" and "YES" will be recognized as a positive answer).
Notes: NoteIn the first test case, Vasya sees the second cell of each row as the same because the second cell of the first row is green and the second cell of the second row is blue, so he can't distinguish these two cells. The rest of the rows are equal in colour. Therefore, Vasya will say that the two rows are coloured the same, even though they aren't.In the second test case, Vasya can see that the two rows are different.In the third test case, every cell is green or blue, so Vasya will think they are the same.

Description: Polycarp has a string $$$s$$$ consisting of lowercase Latin letters.He encodes it using the following algorithm.He goes through the letters of the string $$$s$$$ from left to right and for each letter Polycarp considers its number in the alphabet: if the letter number is single-digit number (less than $$$10$$$), then just writes it out; if the letter number is a two-digit number (greater than or equal to $$$10$$$), then it writes it out and adds the number 0 after. For example, if the string $$$s$$$ is code, then Polycarp will encode this string as follows: 'c' — is the $$$3$$$-rd letter of the alphabet. Consequently, Polycarp adds 3 to the code (the code becomes equal to 3); 'o' — is the $$$15$$$-th letter of the alphabet. Consequently, Polycarp adds 15 to the code and also 0 (the code becomes 3150); 'd' — is the $$$4$$$-th letter of the alphabet. Consequently, Polycarp adds 4 to the code (the code becomes 31504); 'e' — is the $$$5$$$-th letter of the alphabet. Therefore, Polycarp adds 5 to the code (the code becomes 315045). Thus, code of string code is 315045.You are given a string $$$t$$$ resulting from encoding the string $$$s$$$. Your task is to decode it (get the original string $$$s$$$ by $$$t$$$).
Input Specification: The first line of the input contains an integer $$$q$$$ ($$$1 \le q \le 10^4$$$) — the number of test cases in the input. The descriptions of the test cases follow. The first line of description of each test case contains one integer $$$n$$$ ($$$1 \le n \le 50$$$) — the length of the given code. The second line of the description of each test case contains a string $$$t$$$ of length $$$n$$$ — the given code. It is guaranteed that there exists such a string of lowercase Latin letters, as a result of encoding which the string $$$t$$$ is obtained.
Output Specification: For each test case output the required string $$$s$$$ — the string that gives string $$$t$$$ as the result of encoding. It is guaranteed that such a string always exists. It can be shown that such a string is always unique.
Notes: NoteThe first test case is explained above.In the second test case, the answer is aj. Indeed, the number of the letter a is equal to $$$1$$$, so 1 will be appended to the code. The number of the letter j is $$$10$$$, so 100 will be appended to the code. The resulting code is 1100.There are no zeros in the third test case, which means that the numbers of all letters are less than $$$10$$$ and are encoded as one digit. The original string is abacaba.In the fourth test case, the string $$$s$$$ is equal to ll. The letter l has the number $$$12$$$ and is encoded as 120. So ll is indeed 120120.

Complete the code in python to solve this programming problem:
Description: Vlad went into his appartment house entrance, now he is on the $$$1$$$-th floor. He was going to call the elevator to go up to his apartment.There are only two elevators in his house. Vlad knows for sure that: the first elevator is currently on the floor $$$a$$$ (it is currently motionless), the second elevator is located on floor $$$b$$$ and goes to floor $$$c$$$ ($$$b \ne c$$$). Please note, if $$$b=1$$$, then the elevator is already leaving the floor $$$1$$$ and Vlad does not have time to enter it. If you call the first elevator, it will immediately start to go to the floor $$$1$$$. If you call the second one, then first it will reach the floor $$$c$$$ and only then it will go to the floor $$$1$$$. It takes $$$|x - y|$$$ seconds for each elevator to move from floor $$$x$$$ to floor $$$y$$$.Vlad wants to call an elevator that will come to him faster. Help him choose such an elevator.
Input Specification: The first line of the input contains the only $$$t$$$ ($$$1 \le t \le 10^4$$$) — the number of test cases. This is followed by $$$t$$$ lines, three integers each $$$a$$$, $$$b$$$ and $$$c$$$ ($$$1 \le a, b, c \le 10^8$$$, $$$b \ne c$$$) — floor numbers described in the statement.
Output Specification: Output $$$t$$$ numbers, each of which is the answer to the corresponding test case. As an answer, output: $$$1$$$, if it is better to call the first elevator; $$$2$$$, if it is better to call the second one; $$$3$$$, if it doesn't matter which elevator to call (both elevators will arrive in the same time).
Notes: NoteIn the first test case of the example, the first elevator is already on the floor of $$$1$$$.In the second test case of the example, when called, the elevators would move as follows: At the time of the call, the first elevator is on the floor of $$$3$$$, and the second one is on the floor of $$$1$$$, but is already going to another floor; in $$$1$$$ second after the call, the first elevator would be on the floor $$$2$$$, the second one would also reach the floor $$$2$$$ and now can go to the floor $$$1$$$; in $$$2$$$ seconds, any elevator would reach the floor $$$1$$$. In the third test case of the example, the first elevator will arrive in $$$2$$$ seconds, and the second in $$$1$$$.

Complete the code in python to solve this programming problem:
Description: You are given two non-empty strings $$$s$$$ and $$$t$$$, consisting of Latin letters.In one move, you can choose an occurrence of the string $$$t$$$ in the string $$$s$$$ and replace it with dots.Your task is to remove all occurrences of the string $$$t$$$ in the string $$$s$$$ in the minimum number of moves, and also calculate how many different sequences of moves of the minimum length exist.Two sequences of moves are considered different if the sets of indices at which the removed occurrences of the string $$$t$$$ in $$$s$$$ begin differ. For example, the sets $$$\{1, 2, 3\}$$$ and $$$\{1, 2, 4\}$$$ are considered different, the sets $$$\{2, 4, 6\}$$$ and $$$\{2, 6\}$$$ — too, but sets $$$\{3, 5\}$$$ and $$$\{5, 3\}$$$ — not.For example, let the string $$$s =$$$ "abababacababa" and the string $$$t =$$$ "aba". We can remove all occurrences of the string $$$t$$$ in $$$2$$$ moves by cutting out the occurrences of the string $$$t$$$ at the $$$3$$$th and $$$9$$$th positions. In this case, the string $$$s$$$ is an example of the form "ab...bac...ba". It is also possible to cut occurrences of the string $$$t$$$ at the $$$3$$$th and $$$11$$$th positions. There are two different sequences of minimum length moves.Since the answer can be large, output it modulo $$$10^9 + 7$$$.
Input Specification: The first line of the input contains a single integer $$$q$$$ ($$$1 \le q \le 50$$$) — the number of test cases. The descriptions of the sets follow. The first line of each set contains a non-empty string $$$s$$$ ($$$1 \le |s| \le 500$$$) consisting of lowercase Latin letters. The second line of each set contains a non-empty string $$$t$$$ ($$$1 \le |t| \le 500$$$) consisting of lowercase Latin letters. It is guaranteed that the sum of string lengths $$$s$$$ over all test cases does not exceed $$$500$$$. Similarly, it is guaranteed that the sum of string lengths $$$t$$$ over all test cases does not exceed $$$500$$$.
Output Specification: For each test case print two integers — the minimum number of moves and the number of different optimal sequences, modulo $$$10^9 + 7$$$.
Notes: NoteThe first test case is explained in the statement.In the second case, it is enough to cut any of the four occurrences.In the third case, string $$$s$$$ is the concatenation of two strings $$$t =$$$ "xyz", so there is a unique optimal sequence of $$$2$$$ moves.In the fourth and sixth cases, the string $$$s$$$ initially contains no occurrences of the string $$$t$$$.In the fifth case, the string $$$s$$$ contains exactly one occurrence of the string $$$t$$$.

Complete the code in python to solve this programming problem:
Description: You are given two non-empty strings $$$s$$$ and $$$t$$$, consisting of Latin letters.In one move, you can choose an occurrence of the string $$$t$$$ in the string $$$s$$$ and replace it with dots.Your task is to remove all occurrences of the string $$$t$$$ in the string $$$s$$$ in the minimum number of moves, and also calculate how many different sequences of moves of the minimum length exist.Two sequences of moves are considered different if the sets of indices at which the removed occurrences of the string $$$t$$$ in $$$s$$$ begin differ. For example, the sets $$$\{1, 2, 3\}$$$ and $$$\{1, 2, 4\}$$$ are considered different, the sets $$$\{2, 4, 6\}$$$ and $$$\{2, 6\}$$$ — too, but sets $$$\{3, 5\}$$$ and $$$\{5, 3\}$$$ — not.For example, let the string $$$s =$$$ "abababacababa" and the string $$$t =$$$ "aba". We can remove all occurrences of the string $$$t$$$ in $$$2$$$ moves by cutting out the occurrences of the string $$$t$$$ at the $$$3$$$th and $$$9$$$th positions. In this case, the string $$$s$$$ is an example of the form "ab...bac...ba". It is also possible to cut occurrences of the string $$$t$$$ at the $$$3$$$th and $$$11$$$th positions. There are two different sequences of minimum length moves.Since the answer can be large, output it modulo $$$10^9 + 7$$$.
Input Specification: The first line of the input contains a single integer $$$q$$$ ($$$1 \le q \le 50$$$) — the number of test cases. The descriptions of the sets follow. The first line of each set contains a non-empty string $$$s$$$ ($$$1 \le |s| \le 500$$$) consisting of lowercase Latin letters. The second line of each set contains a non-empty string $$$t$$$ ($$$1 \le |t| \le 500$$$) consisting of lowercase Latin letters. It is guaranteed that the sum of string lengths $$$s$$$ over all test cases does not exceed $$$500$$$. Similarly, it is guaranteed that the sum of string lengths $$$t$$$ over all test cases does not exceed $$$500$$$.
Output Specification: For each test case print two integers — the minimum number of moves and the number of different optimal sequences, modulo $$$10^9 + 7$$$.
Notes: NoteThe first test case is explained in the statement.In the second case, it is enough to cut any of the four occurrences.In the third case, string $$$s$$$ is the concatenation of two strings $$$t =$$$ "xyz", so there is a unique optimal sequence of $$$2$$$ moves.In the fourth and sixth cases, the string $$$s$$$ initially contains no occurrences of the string $$$t$$$.In the fifth case, the string $$$s$$$ contains exactly one occurrence of the string $$$t$$$.

Complete the code in python to solve this programming problem:
Description: Given the string $$$s$$$ of decimal digits (0-9) of length $$$n$$$.A substring is a sequence of consecutive characters of a string. The substring of this string is defined by a pair of indexes — with its left and right ends. So, each pair of indexes ($$$l, r$$$), where $$$1 \le l \le r \le n$$$, corresponds to a substring of the string $$$s$$$. We will define as $$$v(l,r)$$$ the numeric value of the corresponding substring (leading zeros are allowed in it).For example, if $$$n=7$$$, $$$s=$$$"1003004", then $$$v(1,3)=100$$$, $$$v(2,3)=0$$$ and $$$v(2,7)=3004$$$.You are given $$$n$$$, $$$s$$$ and an integer $$$w$$$ ($$$1 \le w < n$$$).You need to process $$$m$$$ queries, each of which is characterized by $$$3$$$ numbers $$$l_i, r_i, k_i$$$ ($$$1 \le l_i \le r_i \le n; 0 \le k_i \le 8$$$).The answer to the $$$i$$$th query is such a pair of substrings of length $$$w$$$ that if we denote them as $$$(L_1, L_1+w-1)$$$ and $$$(L_2, L_2+w-1)$$$, then: $$$L_1 \ne L_2$$$, that is, the substrings are different; the remainder of dividing a number $$$v(L_1, L_1+w-1) \cdot v(l_i, r_i) + v(L_2, L_2 + w - 1)$$$ by $$$9$$$ is equal to $$$k_i$$$. If there are many matching substring pairs, then find a pair where $$$L_1$$$ is as small as possible. If there are many matching pairs in this case, then minimize $$$L_2$$$.Note that the answer may not exist.
Input Specification: The first line contains a single integer $$$t$$$ ($$$1 \le t \le 10^4$$$) — number of input test cases. The first line of each test case contains a string $$$s$$$, which contains only the characters 0-9 and has a length $$$n$$$ ($$$2 \le n \le 2 \cdot 10^5$$$). The second line contains two integers $$$w, m$$$ ($$$1 \le w < n, 1 \le m \le 2 \cdot 10^5$$$), where $$$n$$$ — is the length of the given string $$$s$$$. The number $$$w$$$ denotes the lengths of the substrings being searched for, and $$$m$$$ is the number of queries to be processed. The following $$$m$$$ lines contain integers $$$l_i, r_i, k_i$$$ ($$$1 \le l_i \le r_i \le n$$$, $$$0 \le k_i \le 8$$$) — $$$i$$$th query parameters. It is guaranteed that the sum of $$$n$$$ over all test cases does not exceed $$$2 \cdot 10^5$$$. It is also guaranteed that the sum of $$$m$$$ over all test cases does not exceed $$$2 \cdot 10^5$$$.
Output Specification: For each request, print in a separate line: left borders of the required substrings: $$$L_1$$$ and $$$L_2$$$; -1 -1 otherwise, if there is no solution. If there are several solutions, minimize $$$L_1$$$ first, and minimize $$$L_2$$$ second.
Notes: NoteConsider the first test case of example inputs. In this test case $$$n=7$$$, $$$s=$$$"1003004", $$$w=4$$$ and one query $$$l_1=1$$$, $$$r_1=2$$$, $$$k_1=1$$$. Note that $$$v(1,2)=10$$$. We need to find a pair of substrings of length $$$4$$$ such that $$$v(L_1, L_1+3)\cdot10+v(L_2,L_2+3)$$$ has a remainder of $$$k_1=1$$$ when divided by $$$9$$$. The values $$$L_1=2, L_2=4$$$ actually satisfy all the requirements: $$$v(L_1, L_1+w-1)=v(2,5)=30$$$, $$$v(L_2, L_2+w-1)=v(4,7)=3004$$$. Indeed, $$$30\cdot10+3004=3304$$$, which has a remainder of $$$1$$$ when divided by $$$9$$$. It can be shown that $$$L_1=2$$$ is the minimum possible value, and $$$L_2=4$$$ is the minimum possible with $$$L_1=2$$$.

Description: You are an ambitious king who wants to be the Emperor of The Reals. But to do that, you must first become Emperor of The Integers.Consider a number axis. The capital of your empire is initially at $$$0$$$. There are $$$n$$$ unconquered kingdoms at positions $$$0<x_1<x_2<\ldots<x_n$$$. You want to conquer all other kingdoms.There are two actions available to you: You can change the location of your capital (let its current position be $$$c_1$$$) to any other conquered kingdom (let its position be $$$c_2$$$) at a cost of $$$a\cdot |c_1-c_2|$$$. From the current capital (let its current position be $$$c_1$$$) you can conquer an unconquered kingdom (let its position be $$$c_2$$$) at a cost of $$$b\cdot |c_1-c_2|$$$. You cannot conquer a kingdom if there is an unconquered kingdom between the target and your capital. Note that you cannot place the capital at a point without a kingdom. In other words, at any point, your capital can only be at $$$0$$$ or one of $$$x_1,x_2,\ldots,x_n$$$. Also note that conquering a kingdom does not change the position of your capital.Find the minimum total cost to conquer all kingdoms. Your capital can be anywhere at the end.
Input Specification: The first line contains a single integer $$$t$$$ ($$$1 \le t \le 1000$$$) — the number of test cases. The description of each test case follows. The first line of each test case contains $$$3$$$ integers $$$n$$$, $$$a$$$, and $$$b$$$ ($$$1 \leq n \leq 2 \cdot 10^5$$$; $$$1 \leq a,b \leq 10^5$$$). The second line of each test case contains $$$n$$$ integers $$$x_1, x_2, \ldots, x_n$$$ ($$$1 \leq x_1 < x_2 < \ldots < x_n \leq 10^8$$$). The sum of $$$n$$$ over all test cases does not exceed $$$2 \cdot 10^5$$$.
Output Specification: For each test case, output a single integer — the minimum cost to conquer all kingdoms.
Notes: NoteHere is an optimal sequence of moves for the second test case: Conquer the kingdom at position $$$1$$$ with cost $$$3\cdot(1-0)=3$$$. Move the capital to the kingdom at position $$$1$$$ with cost $$$6\cdot(1-0)=6$$$. Conquer the kingdom at position $$$5$$$ with cost $$$3\cdot(5-1)=12$$$. Move the capital to the kingdom at position $$$5$$$ with cost $$$6\cdot(5-1)=24$$$. Conquer the kingdom at position $$$6$$$ with cost $$$3\cdot(6-5)=3$$$. Conquer the kingdom at position $$$21$$$ with cost $$$3\cdot(21-5)=48$$$. Conquer the kingdom at position $$$30$$$ with cost $$$3\cdot(30-5)=75$$$. The total cost is $$$3+6+12+24+3+48+75=171$$$. You cannot get a lower cost than this.

Description: You are an ambitious king who wants to be the Emperor of The Reals. But to do that, you must first become Emperor of The Integers.Consider a number axis. The capital of your empire is initially at $$$0$$$. There are $$$n$$$ unconquered kingdoms at positions $$$0<x_1<x_2<\ldots<x_n$$$. You want to conquer all other kingdoms.There are two actions available to you: You can change the location of your capital (let its current position be $$$c_1$$$) to any other conquered kingdom (let its position be $$$c_2$$$) at a cost of $$$a\cdot |c_1-c_2|$$$. From the current capital (let its current position be $$$c_1$$$) you can conquer an unconquered kingdom (let its position be $$$c_2$$$) at a cost of $$$b\cdot |c_1-c_2|$$$. You cannot conquer a kingdom if there is an unconquered kingdom between the target and your capital. Note that you cannot place the capital at a point without a kingdom. In other words, at any point, your capital can only be at $$$0$$$ or one of $$$x_1,x_2,\ldots,x_n$$$. Also note that conquering a kingdom does not change the position of your capital.Find the minimum total cost to conquer all kingdoms. Your capital can be anywhere at the end.
Input Specification: The first line contains a single integer $$$t$$$ ($$$1 \le t \le 1000$$$) — the number of test cases. The description of each test case follows. The first line of each test case contains $$$3$$$ integers $$$n$$$, $$$a$$$, and $$$b$$$ ($$$1 \leq n \leq 2 \cdot 10^5$$$; $$$1 \leq a,b \leq 10^5$$$). The second line of each test case contains $$$n$$$ integers $$$x_1, x_2, \ldots, x_n$$$ ($$$1 \leq x_1 < x_2 < \ldots < x_n \leq 10^8$$$). The sum of $$$n$$$ over all test cases does not exceed $$$2 \cdot 10^5$$$.
Output Specification: For each test case, output a single integer — the minimum cost to conquer all kingdoms.
Notes: NoteHere is an optimal sequence of moves for the second test case: Conquer the kingdom at position $$$1$$$ with cost $$$3\cdot(1-0)=3$$$. Move the capital to the kingdom at position $$$1$$$ with cost $$$6\cdot(1-0)=6$$$. Conquer the kingdom at position $$$5$$$ with cost $$$3\cdot(5-1)=12$$$. Move the capital to the kingdom at position $$$5$$$ with cost $$$6\cdot(5-1)=24$$$. Conquer the kingdom at position $$$6$$$ with cost $$$3\cdot(6-5)=3$$$. Conquer the kingdom at position $$$21$$$ with cost $$$3\cdot(21-5)=48$$$. Conquer the kingdom at position $$$30$$$ with cost $$$3\cdot(30-5)=75$$$. The total cost is $$$3+6+12+24+3+48+75=171$$$. You cannot get a lower cost than this.

Description: Team Red and Team Blue competed in a competitive FPS. Their match was streamed around the world. They played a series of $$$n$$$ matches.In the end, it turned out Team Red won $$$r$$$ times and Team Blue won $$$b$$$ times. Team Blue was less skilled than Team Red, so $$$b$$$ was strictly less than $$$r$$$.You missed the stream since you overslept, but you think that the match must have been neck and neck since so many people watched it. So you imagine a string of length $$$n$$$ where the $$$i$$$-th character denotes who won the $$$i$$$-th match — it is R if Team Red won or B if Team Blue won. You imagine the string was such that the maximum number of times a team won in a row was as small as possible. For example, in the series of matches RBBRRRB, Team Red won $$$3$$$ times in a row, which is the maximum.You must find a string satisfying the above conditions. If there are multiple answers, print any.
Input Specification: The first line contains a single integer $$$t$$$ ($$$1 \le t \le 1000$$$) — the number of test cases. Each test case has a single line containing three integers $$$n$$$, $$$r$$$, and $$$b$$$ ($$$3 \leq n \leq 100$$$; $$$1 \leq b < r \leq n$$$, $$$r+b=n$$$).
Output Specification: For each test case, output a single line containing a string satisfying the given conditions. If there are multiple answers, print any.
Notes: NoteThe first test case of the first example gives the optimal answer for the example in the statement. The maximum number of times a team wins in a row in RBRBRBR is $$$1$$$. We cannot minimize it any further.The answer for the second test case of the second example is RRBRBRBRBR. The maximum number of times a team wins in a row is $$$2$$$, given by RR at the beginning. We cannot minimize the answer any further.

Complete the code in python to solve this programming problem:
Description: Team Red and Team Blue competed in a competitive FPS. Their match was streamed around the world. They played a series of $$$n$$$ matches.In the end, it turned out Team Red won $$$r$$$ times and Team Blue won $$$b$$$ times. Team Blue was less skilled than Team Red, so $$$b$$$ was strictly less than $$$r$$$.You missed the stream since you overslept, but you think that the match must have been neck and neck since so many people watched it. So you imagine a string of length $$$n$$$ where the $$$i$$$-th character denotes who won the $$$i$$$-th match — it is R if Team Red won or B if Team Blue won. You imagine the string was such that the maximum number of times a team won in a row was as small as possible. For example, in the series of matches RBBRRRB, Team Red won $$$3$$$ times in a row, which is the maximum.You must find a string satisfying the above conditions. If there are multiple answers, print any.
Input Specification: The first line contains a single integer $$$t$$$ ($$$1 \le t \le 1000$$$) — the number of test cases. Each test case has a single line containing three integers $$$n$$$, $$$r$$$, and $$$b$$$ ($$$3 \leq n \leq 100$$$; $$$1 \leq b < r \leq n$$$, $$$r+b=n$$$).
Output Specification: For each test case, output a single line containing a string satisfying the given conditions. If there are multiple answers, print any.
Notes: NoteThe first test case of the first example gives the optimal answer for the example in the statement. The maximum number of times a team wins in a row in RBRBRBR is $$$1$$$. We cannot minimize it any further.The answer for the second test case of the second example is RRBRBRBRBR. The maximum number of times a team wins in a row is $$$2$$$, given by RR at the beginning. We cannot minimize the answer any further.

Complete the code in python to solve this programming problem:
Description: Suppose you had an array $$$A$$$ of $$$n$$$ elements, each of which is $$$0$$$ or $$$1$$$.Let us define a function $$$f(k,A)$$$ which returns another array $$$B$$$, the result of sorting the first $$$k$$$ elements of $$$A$$$ in non-decreasing order. For example, $$$f(4,[0,1,1,0,0,1,0]) = [0,0,1,1,0,1,0]$$$. Note that the first $$$4$$$ elements were sorted.Now consider the arrays $$$B_1, B_2,\ldots, B_n$$$ generated by $$$f(1,A), f(2,A),\ldots,f(n,A)$$$. Let $$$C$$$ be the array obtained by taking the element-wise sum of $$$B_1, B_2,\ldots, B_n$$$.For example, let $$$A=[0,1,0,1]$$$. Then we have $$$B_1=[0,1,0,1]$$$, $$$B_2=[0,1,0,1]$$$, $$$B_3=[0,0,1,1]$$$, $$$B_4=[0,0,1,1]$$$. Then $$$C=B_1+B_2+B_3+B_4=[0,1,0,1]+[0,1,0,1]+[0,0,1,1]+[0,0,1,1]=[0,2,2,4]$$$.You are given $$$C$$$. Determine a binary array $$$A$$$ that would give $$$C$$$ when processed as above. It is guaranteed that an array $$$A$$$ exists for given $$$C$$$ in the input.
Input Specification: The first line contains a single integer $$$t$$$ ($$$1 \leq t \leq 1000$$$) — the number of test cases. Each test case has two lines. The first line contains a single integer $$$n$$$ ($$$1 \leq n \leq 2 \cdot 10^5$$$). The second line contains $$$n$$$ integers $$$c_1, c_2, \ldots, c_n$$$ ($$$0 \leq c_i \leq n$$$). It is guaranteed that a valid array $$$A$$$ exists for the given $$$C$$$. The sum of $$$n$$$ over all test cases does not exceed $$$2 \cdot 10^5$$$.
Output Specification: For each test case, output a single line containing $$$n$$$ integers $$$a_1, a_2, \ldots, a_n$$$ ($$$a_i$$$ is $$$0$$$ or $$$1$$$). If there are multiple answers, you may output any of them.
Notes: NoteHere's the explanation for the first test case. Given that $$$A=[1,1,0,1]$$$, we can construct each $$$B_i$$$: $$$B_1=[\color{blue}{1},1,0,1]$$$; $$$B_2=[\color{blue}{1},\color{blue}{1},0,1]$$$; $$$B_3=[\color{blue}{0},\color{blue}{1},\color{blue}{1},1]$$$; $$$B_4=[\color{blue}{0},\color{blue}{1},\color{blue}{1},\color{blue}{1}]$$$ And then, we can sum up each column above to get $$$C=[1+1+0+0,1+1+1+1,0+0+1+1,1+1+1+1]=[2,4,2,4]$$$.

Complete the code in python to solve this programming problem:
Description: Suppose you had an array $$$A$$$ of $$$n$$$ elements, each of which is $$$0$$$ or $$$1$$$.Let us define a function $$$f(k,A)$$$ which returns another array $$$B$$$, the result of sorting the first $$$k$$$ elements of $$$A$$$ in non-decreasing order. For example, $$$f(4,[0,1,1,0,0,1,0]) = [0,0,1,1,0,1,0]$$$. Note that the first $$$4$$$ elements were sorted.Now consider the arrays $$$B_1, B_2,\ldots, B_n$$$ generated by $$$f(1,A), f(2,A),\ldots,f(n,A)$$$. Let $$$C$$$ be the array obtained by taking the element-wise sum of $$$B_1, B_2,\ldots, B_n$$$.For example, let $$$A=[0,1,0,1]$$$. Then we have $$$B_1=[0,1,0,1]$$$, $$$B_2=[0,1,0,1]$$$, $$$B_3=[0,0,1,1]$$$, $$$B_4=[0,0,1,1]$$$. Then $$$C=B_1+B_2+B_3+B_4=[0,1,0,1]+[0,1,0,1]+[0,0,1,1]+[0,0,1,1]=[0,2,2,4]$$$.You are given $$$C$$$. Determine a binary array $$$A$$$ that would give $$$C$$$ when processed as above. It is guaranteed that an array $$$A$$$ exists for given $$$C$$$ in the input.
Input Specification: The first line contains a single integer $$$t$$$ ($$$1 \leq t \leq 1000$$$) — the number of test cases. Each test case has two lines. The first line contains a single integer $$$n$$$ ($$$1 \leq n \leq 2 \cdot 10^5$$$). The second line contains $$$n$$$ integers $$$c_1, c_2, \ldots, c_n$$$ ($$$0 \leq c_i \leq n$$$). It is guaranteed that a valid array $$$A$$$ exists for the given $$$C$$$. The sum of $$$n$$$ over all test cases does not exceed $$$2 \cdot 10^5$$$.
Output Specification: For each test case, output a single line containing $$$n$$$ integers $$$a_1, a_2, \ldots, a_n$$$ ($$$a_i$$$ is $$$0$$$ or $$$1$$$). If there are multiple answers, you may output any of them.
Notes: NoteHere's the explanation for the first test case. Given that $$$A=[1,1,0,1]$$$, we can construct each $$$B_i$$$: $$$B_1=[\color{blue}{1},1,0,1]$$$; $$$B_2=[\color{blue}{1},\color{blue}{1},0,1]$$$; $$$B_3=[\color{blue}{0},\color{blue}{1},\color{blue}{1},1]$$$; $$$B_4=[\color{blue}{0},\color{blue}{1},\color{blue}{1},\color{blue}{1}]$$$ And then, we can sum up each column above to get $$$C=[1+1+0+0,1+1+1+1,0+0+1+1,1+1+1+1]=[2,4,2,4]$$$.

Output Specification: For each test case, output a single line containing $$$n$$$ integers $$$a_1, a_2, \ldots, a_n$$$ ($$$a_i$$$ is $$$0$$$ or $$$1$$$). If there are multiple answers, you may output any of them.
Notes: NoteHere's the explanation for the first test case. Given that $$$A=[1,1,0,1]$$$, we can construct each $$$B_i$$$: $$$B_1=[\color{blue}{1},1,0,1]$$$; $$$B_2=[\color{blue}{1},\color{blue}{1},0,1]$$$; $$$B_3=[\color{blue}{0},\color{blue}{1},\color{blue}{1},1]$$$; $$$B_4=[\color{blue}{0},\color{blue}{1},\color{blue}{1},\color{blue}{1}]$$$ And then, we can sum up each column above to get $$$C=[1+1+0+0,1+1+1+1,0+0+1+1,1+1+1+1]=[2,4,2,4]$$$.

Complete the code in python to solve this programming problem:
Description: There is an undirected, connected graph with $$$n$$$ vertices and $$$m$$$ weighted edges. A walk from vertex $$$u$$$ to vertex $$$v$$$ is defined as a sequence of vertices $$$p_1,p_2,\ldots,p_k$$$ (which are not necessarily distinct) starting with $$$u$$$ and ending with $$$v$$$, such that $$$p_i$$$ and $$$p_{i+1}$$$ are connected by an edge for $$$1 \leq i < k$$$.We define the length of a walk as follows: take the ordered sequence of edges and write down the weights on each of them in an array. Now, write down the bitwise AND of every nonempty prefix of this array. The length of the walk is the MEX of all these values.More formally, let us have $$$[w_1,w_2,\ldots,w_{k-1}]$$$ where $$$w_i$$$ is the weight of the edge between $$$p_i$$$ and $$$p_{i+1}$$$. Then the length of the walk is given by $$$\mathrm{MEX}(\{w_1,\,w_1\& w_2,\,\ldots,\,w_1\& w_2\& \ldots\& w_{k-1}\})$$$, where $$$\&$$$ denotes the bitwise AND operation.Now you must process $$$q$$$ queries of the form u v. For each query, find the minimum possible length of a walk from $$$u$$$ to $$$v$$$.The MEX (minimum excluded) of a set is the smallest non-negative integer that does not belong to the set. For instance: The MEX of $$$\{2,1\}$$$ is $$$0$$$, because $$$0$$$ does not belong to the set. The MEX of $$$\{3,1,0\}$$$ is $$$2$$$, because $$$0$$$ and $$$1$$$ belong to the set, but $$$2$$$ does not. The MEX of $$$\{0,3,1,2\}$$$ is $$$4$$$ because $$$0$$$, $$$1$$$, $$$2$$$ and $$$3$$$ belong to the set, but $$$4$$$ does not.
Input Specification: The first line contains two integers $$$n$$$ and $$$m$$$ ($$$2 \leq n \leq 10^5$$$; $$$n-1 \leq m \leq \min{\left(\frac{n(n-1)}{2},10^5\right)}$$$). Each of the next $$$m$$$ lines contains three integers $$$a$$$, $$$b$$$, and $$$w$$$ ($$$1 \leq a, b \leq n$$$, $$$a \neq b$$$; $$$0 \leq w < 2^{30}$$$) indicating an undirected edge between vertex $$$a$$$ and vertex $$$b$$$ with weight $$$w$$$. The input will not contain self-loops or duplicate edges, and the provided graph will be connected. The next line contains a single integer $$$q$$$ ($$$1 \leq q \leq 10^5$$$). Each of the next $$$q$$$ lines contains two integers $$$u$$$ and $$$v$$$ ($$$1 \leq u, v \leq n$$$, $$$u \neq v$$$), the description of each query.
Output Specification: For each query, print one line containing a single integer — the answer to the query.
Notes: NoteThe following is an explanation of the first example. The graph in the first example. Here is one possible walk for the first query:$$$$$$1 \overset{5}{\rightarrow} 3 \overset{3}{\rightarrow} 2 \overset{1}{\rightarrow} 1 \overset{5}{\rightarrow} 3 \overset{1}{\rightarrow} 4 \overset{2}{\rightarrow} 5.$$$$$$The array of weights is $$$w=[5,3,1,5,1,2]$$$. Now if we take the bitwise AND of every prefix of this array, we get the set $$$\{5,1,0\}$$$. The MEX of this set is $$$2$$$. We cannot get a walk with a smaller length (as defined in the statement).

The input will not contain self-loops or duplicate edges, and the provided graph will be connected. The next line contains a single integer $$$q$$$ ($$$1 \leq q \leq 10^5$$$). Each of the next $$$q$$$ lines contains two integers $$$u$$$ and $$$v$$$ ($$$1 \leq u, v \leq n$$$, $$$u \neq v$$$), the description of each query.
