Your algorithm should run in O(n) time and uses constant space. Given a string str, the task is to print all the permutations of str.A permutation is an arrangement of all or part of a set of objects, with regard to the order of the arrangement. For example, lexicographically next permutation of “gfg” is “ggf” and next permutation of “acb” is “bac”. Example: Given [1,2,0] return 3, [3,4,-1,1] return 2, [-8, -7, -6] returns 1 Your algorithm should run in O(n) time and use constant space. Find Permutation: Given a positive integer n and a string s consisting only of letters D or I, you have to find any permutation of first n positive integer that satisfy the given input string.
