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.

Four more days and it's Starters time: https://bit.ly/3wK6F6g! We all are excited to see you guys ramp up for the programming battle. Go ahead and set a reminder for the contest this Wednesday, November 17 at 8 PM IST.

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
