WebJan 28, 2024 · Simple permutation example: "AB" has 2 permutations: "AB" and "BA". Repetition example: "AAB" has 6 permutations: "AAB", "ABA", "BAA", "BAA", "ABA", "AAB". Notice there are repeated characters, this is a permutation with repetition allowed (as each "A" is treated as distinct). WebJan 7, 2024 · But this method doesn’t provide unique permutations. Hence to ensure that any permutation is not repeated, we use a set and follow the below conditions: If the permutation is not present in the set, print it and insert it in the set. Increment the count of number of unique permutations. Else, move on to the next permutation.
