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 ...

If we're making all permutations for "cat," we take all permutations for "ca" and then put "t" in each possible position in each of those permutations. We use this approach recursively: # Recursive ...

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