Hi, As a struggling newbie, I've started to try various exercises in order to improve. I decided to try the latest Ruby Quiz (http://www.rubyquiz.com/quiz131.html) in Haskell. Would someone be kind enough to cast their eye over my code? I get the feeling there's a better way of doing it! subarrays :: [a] -> [[a]] subarrays [] = [[]] subarrays xs = (sa xs) ++ subarrays (tail xs) where sa xs = [ys | n <- [1..length xs], ys <- [(take n xs)]] maxsubarrays :: [Integer] -> [Integer] maxsubarrays xs = msa [] (subarrays xs) where msa m [] = m msa m (x:xs) | sum x > sum m = msa x xs | otherwise = msa m xs --for testing: should return [2, 5, -1, 3] main = maxsubarrays [-1, 2, 5, -1, 3, -2, 1] I've read tutorials about the syntax of Haskell, but I can't seem to find any that teach you how to really "think" in a Haskell way. Is there anything (books, online tutorials, exercises) that anyone could recommend? Thanks, James
