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 ...

The C# console application prompts the user to input a string or a list of numbers. It then uses the method GetPermutations to calculate all possible permutations of the input. The method works by ...
