// Given a string S, find and return all the possible permutations of the input string. // Note 1 : The order of permutations is not important. // Note 2 : If original string contains duplicate ...
* Return all the permutations of the given string in any order, * as they will be sorted at the back-end before printing.
- 1) to different permutations. A recursive approach (which is what I would use) would involve breaking the problem into isomorphic subproblems: to find all permutations of a string, find all ...
