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,
jynx

erix learned the word 'portaging' not so long ago (from vikings lugging their ships from one river-system to another)
[choroba]: my best run so far
[erix]: I think they build a portaging installation for yachts here not so long ago - lemme google it
[erix]: choroba ah, you should have sprinted 7 s off that :)
[erix]: (but then there's always a next (im)possible goal)
Corion avoids running by starting on time
[choroba]: my phone showed me 1 hour 10 km which was my goal, it changed a bit after uploading to the website
[erix]: choroba I believe you ;)
