I am trying to determine the time and space complexity of this algorithm I created to find all permutations of an array in Python. Is the time complexity O(sum_{k=1}^N P(n,k)) where P(n,k) is a permutation with k factors? class Solution: def permute(self, vals): answer = [vals] def backtrack(i, curr_arr): if i >= len(vals): return curr_val ..
