Task - The title pretty much sums it up: raise an integer x to power x, where 0<x. Restrictions: Use of exponentiation, exp(), ln(), and any other powers-related language built-ins, like pow(), x^x, x**x is forbidden. You can assume that the given integer fits the limits of the programming language of your choice. Test cases: Input | Output --------------- 2 | 4 3 | 27 5 | 3125 6 | 46656 10 | 10000000000 --- This is code-golf, so the shortest program in bytes wins.
