Generate all permutations of array

WebMay 23, 2024 · Permutations inside a k-size element are not counted (i.e. (1,2,3) == (2,1,3) == etc.). The code assumes all elements in the array are unique (I guess it can be added to the basic sanity tests in the beginning, or handled in a way ). The algorithm uses recursion, and some counter array (pushForward) to keep track of the permutations. WebMay 22, 2015 · 3 Answers. Creating (or printing) the permutations of an array is much easier done as a combination of recursively and iteratively than purely iteratively. There are surely iterative ways to do it, but it is particularly simple with a combination. Specifically, note that there are by definition N! permutations of a length N array - N choices ...
