Generating permutations becomes more complex when duplicate characters are present, as we need to ensure that no two permutations are identical. In this tutorial, we’ll walk through handling duplicates efficiently by using backtracking to explore all possible paths while skipping over repeated sequences. Whether you're gearing up for coding interviews or expanding your knowledge of backtracking, this video will give you a clear approach to solving string permutation problems with duplicate characters.
