Given two arrays of equal size N and an integer K. The task is to check if after permuting both arrays, we get sum of their corresponding element greater than or equal to k i.e Ai + Bi >= K for i =0 to N-1. These permutations may or may not include repetitions which can be modified in your program code. #47 Permutations II. Given a string you need to print all possible strings that can be made by placing spaces (zero or one) in between them. We can in-place find all permutations of a given string by using Backtracking. Input: str[] = "ABC" Output: (A B C)(A BC)(AB After reducing to 2 and then 1 item lists, all of them will be found. Solution We can solve this using recursion as well but need to take care of duplicates.We will sort the array, so all duplicates will be conitguous. In this post, we will see how to find permutations of a string containing all distinct characters. For eg, string ABC has 6 permutations.
