WebPermutations — LeetCode Explanation: We can fix the first element of the permutation and say that we want to find permutation of N-1 elements. And then we can choose further by saying we fixed second element. We can keep repeating this approach until we fix all elements of the permutation. WebComplexity Analysis: For the N size of the array, there are a total number of N! permutation. We are checking all of the permutations and each permutation is of the size N. Therefore, the overall time complexity of the program is O(N! * N). The space complexity of the program is O(1), as the program is not using any extra space.
