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. Scrambled string: Given string str, we can represent it as a binary tree by partitioning it into two non-empty substrings recursively. rgeat / \\ rg eat / \\ / \\r g e at / \\ a tWe say that rgeat is a scrambled string of great.Similarly, if we continue to swap the children of nodes eat and at, it produces a scrambled string rgtae.

If not, it indicates that the strings contain different characters and cant be a scrambled form of each other.Below is the implementation of the above approach: Time Complexity: O(2^k + 2^(n-k)), where k and n-k are the length of the two substrings.Auxiliary Space: O(2^N), recursion stack. I.e., It cant accept string argument. A-143, 9th Floor, Sovereign Corporate Tower, We use cookies to ensure you have the best browsing experience on our website. But it is not as simple as shuffling a list. Or maybe I missed one of the usages of random.shuffle(). That is, we get a list containing all the characters of the string (in a random manner). As the generator cannot provide us the size we need to convert it into a list to shuffle it. The compiler will also give a string as output. Further operations will be done in that array. Connect and share knowledge within a single location that is structured and easy to search. C++ Programming - Beginner to Advanced; Java Programming - Beginner to Advanced; C Programming - Beginner to Advanced; Android App Development with Kotlin(Live) Web Development.
