So I have the code

shuffle :: Int -> [a] -> [a] shuffle i [] = [] shuffle i cards = (cards!!i) : shuffle (fst pair) (delete (cards!!i) cards)    where pair = randomR (0, 51) (mkStdGen 42)

and it doesn't work, am I missing something?

Are you familiar with class constraints? Try looking at the type of delete. (Use ":type" at the ghci prompt.) -- Dave Menendez <dave@zednenem.com> <http://www.eyrie.org/~zednenem/>
