You are given two strings, S and T, and q queries (a_i, b_i, c_i, d_i). For each query, determine whether a substring of S can be transformed into a substring of T using specific operations. The operations involve replacing characters and deleting specific substrings. The constraints are: 1 ≤ |S|, |T| ≤ 10^5, S and T consist of letters A and B, and 1 ≤ q ≤ 10^5. The input format includes S, T, q, and the queries. The output should indicate whether each query can be transformed (YES) or not (NO). Sample inputs and outputs are provided for reference.
