in reply to Golf: Selection from sets (Choose)

i'm posting this just to show some different code. The methodolgy doesn't use factorials per se, just lists of numbers. There are probably some ways to optimize, but i don't have enough time to really try right now.

sub c{
   my($c,$d)=@_;my%n=map{$_=>1}1..$c;delete$n{$_}for 1..($c-$d);
   eval join'/',map"($_)",(join'*',keys%n),(join'*',1..$d)
}

It's warnings and strict compliant, and returns all the right answers.

nuf evah,
