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 permutations of the string without a ...

Given a string s (which may contain duplicate characters), generate and return all unique permutations of the string. The order of output doesn't matter, but duplicates must be avoided. Applied ...

Sort the characters of the string to generate permutations in lexicographical order. Use a loop to find the next lexicographical permutation until all permutations are found. DFS with Backtracking: ...

Coding examples emplemented using recursion Design an algorithm to print all permutations of a string. For simplicity, assume all character are unique. Generalizing ...
