Test Instructions Analysis:

Given a string, the string is turned into a binary tree, and if the binary tree is one or more of the left and right sub-trees, the new string is called scramble. Give two strings to determine if each is scramble.

Topic Ideas:

This is a dynamic programming problem in which the characters are split into two parts, and if the two parts satisfy the scramble, then the entire string satisfies the scramble.

Code (Python):
