How开发者_JAVA技巧 can I prove that n! = O(n^n)?I assume that you want to prove that the function n! is an element of the set O(n^n). This can be proven quite easily:
I\'m working on some recursion stuff. I\'ve created some functions in the vein of the twelve days of xmas, but I can\'t think of a way to call a function using input. I\'ll give an example:
I am writing a sudoku solver. It has been a long time since I have touched prolog, thus I don\'t remember everything regarding unification, backtracking, etc. I think that I cause the system to backtr
