Scramble String using Recursion Given a string s1, we may represent it as a binary tree by partitioning it to two non-empty substrings recursively. The basic idea is to divide s1 (s2) into two substrings with length k and len-k and check if the two substrings s1 [0..k-1] and s1 [k, len-1] are the scrambles of s2 [0..k-1] and s2 [k,len-1] or s2 [len-k, len-1] and s2 [0..len-k-1] via recursion.
