In this case, we need to split the string into a list of characters, scramble them with sample (), concatenate them with join (), and then rewrite the list using a list comprehension. Example for sorting the string using python built in . We will look at a simple implementation of this task in Python. 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.
