Check the thread Binomial Expansion there's a really interesting n choose r sub there by ariels and a proof underneath by japhy. (Among other things)
# copy of said subroutine sub nCr { my ($n, $r) = @_; my $res = 1; for my $i (1..$r) { $res *= $n--; $res /= $i; } $res; }

    Thanks! That's a very elegant solution. I spend a day or so comming up with a program to do the same. And that was about a page long. Very nifty.

    Have Fun
