hello, I'm new to haskell, I'm studying for an exam, and I'm having trouble with this exercise.

I have a list of Integers, and I want to return the highest value of all.

i have this: 

comp :: Int -> Int -> Int

comp x y | x < y        = y

               | otherwise   = x

maxList :: [Int] -> [Int]

maxList (x1:x2:xs) = comp x1 x2 : maxList xs

maxList [] = []

 

this code returns a list, but I only want it to return a single Int... but can't seem to do it, could you please help me?
