SPOJ Adding Reversed Numbers

Haskell addiction 😉 . Two lines in Haskell for Adding Reversed Numbers and its making me lazy .

import Data.List

readInt :: String -> Integer 
readInt = read 

solve :: [Integer] -> String 
solve ( x : y :_) = show . readInt .  reverse . show $ x + y

main = interact $ unlines . map ( solve . map ( read.reverse ) . words ) . tail . lines
