The longest decreasing subsequence problem is to find a subsequence of a given sequence in which the subsequence’s elements are in sorted order, highest to lowest, and in which the subsequence is as long as possible.

Given three strings, return true if third string is interleaving of first and second string. i.e., it is formed from all characters of first and second string and order of characters is preserved.

Implement your own diff utility. i.e given two similar strings, efficiently list out all differences between them.

A string is K-Palindrome if it becomes a palindrome on removing at most k characters from it. Write an algorithm to check if a given string is K-Palindrome or not.
