WebJan 15, 2024 · However, the iterative solution will not produce correct permutations for any number apart from 3. For n = 3, you can see that n * (n - 1) * (n-2) = n!. The LHS is O(n^3) (or rather O(n^n) since n=3 here) and the RHS is O(n!). For larger values of the size of the list, say n, you could have n nested WebThis post will discuss how to generate all possible permutations of a list in Python. 1.
