Two strings X and Y are similar if we can swap two letters (in different positions) of X, so that it equals Y. For example, "tars" and "rats" are similar (swapping at positions 0 and 2), and "rats" and "arts" are si…

You are given an array A of strings. Two strings S and T are special-equivalent if after any number of moves, S == T. A move consists of choosing two indices i and j with i % 2 == j % 2, and swapping S[i] with S[j]. Now, a group of special-equivalent…
