You are given a string s of length n consisting only of the characters 'A' and 'B'.

\n\n

You are also given a 2D integer array queries of length q, where each queries[i] is one of the following:

\n\n\n\n

A substring is alternating if no two adjacent characters are equal. A substring of length 1 is always alternating.

\n\n

Return an integer array answer, where answer[i] is the result of the ith query of type [2, l, r].
