[Haskell-cafe] Ultra-newbie Question

Hello Haskell Community - I am a professional programmer with 11 years experience, yet I just do not seem to be able to get the hang of even simple things in Haskell. I am trying to write a function that takes a list and returns the last n elements. There may be a function which I can just call that does that, but I am trying to roll my own just to understand the concept. Let's call the function n_lastn and, given a list [1,2,3,4,5], I would like n_lastn 3 = [3,4,5] Seems like it would be something like: n_lastn:: [a]->Int->[a] n_lastn 1 (xs) = last(xs) n_lastn n (x:xs) = ???? The issue is I do not see how you can store the last elements of the list. Thanks in advance. ctauss
