I can't check right this minute. But if it isn't, we've got a problem. :-) Try to verify that permute(a;b) == a! / (a-b)! For example: permute(5;1) = 5 permute(6;1) = 6 permute(a;1) = a <<--- all positive integers 'a'. permute(5;5) = 5! = 5 * 4 * 3 * 2 * 1 permute(a;a) = a! <<--- all positive integers 'a'. permute(2;2) = 2 permute(3;3) = 6 permute(4;4) = 24 permute(5;5) = 120 permute(6;6) = 720 Cheers, -- Daniel Carrera | I don't want it perfect, Join OOoAuthors today! | I want it Tuesday. http://oooauthors.org |
