We call a string S valid if either S = ? or S = (x + y) or S = (x - y) where x and y are valid strings. The power of a valid string S is defined as the maximum value that can be attained by replacing each '?' in it either by 0 or 1 and evaluating the resulting expression. Chef is given a valid string S and Q queries on it. For each query, he is given two integers L and R (L <= R) such that the substring S[L...R] is valid. Help Chef in finding the power of this valid substring for all queries.

You are given a binary string S of length N. You can perform the following operations on S:
Flip: Pick an index i (1 <= i <= N) and flip the i-th character (i.e. change 0 to 1 or 1 to 0)
Compress: Pick any non-empty substring consisting of the same character and replace it with a single occurrence of that character.
Find the minimum number of operations required to make all the characters of S equal.

The functional array of an array A=[A_1, A_2, ... A_N] is the array fA of size N−1, where fA_i = A_{i+1} - A_i for 1≤i<N. You are given two arrays B=[B_1, B_2....B_N] and Z=[Z_1,Z_2,...Z_M]. Find out whether there exists an array A such that:
- B is a subsequence of A
- fA is a subsequence of Z
