How to find all permutation of a String using recursion is one of the tricky coding questions from programming job interviews. Permutation is denoted as nPr and combination is denoted as nCr. Here is my solution … In one operation he can swap Ax and Ay only if (x, y) is a good pair. Privacy Policy. Phase1: Take 2 pointers slow and fast. Privacy Policy. The solution contains 2 parts as is the case when we need to find the start node of a loop in a linked list. Permutations: Given a collection of numbers, return all possible permutations. Given a string of length m containing lowercase alphabets only. It’s a tricky question and asked mostly in Java interviews. Given an unsorted integer array, find the first missing positive integer.
