Need help writing simple Haskell program please

  1. May 7, 2012 #1
    So for my program I want to input this line of code:

    addPairs 10 [(2,3),(4,15),(87,92),(23,45)]

    Where the 10 after addPairs is the minimum distance the pair (x,y) must have in order to be outputted as [x+y]
    For example :
    addPairs 10 [(2,3),(4,15),(87,92),(23,45)]

    would output:
    [ 19, 68 ]

    SO far this is what I have:

    diffTuple :: (Int,Int) -> Int
    diffTuple (x,y) = abs (x-y)

    addDistantPairs :: addDistantPairs :: Int -> [(Int,Int)] -> [ Int ]
    addDistantPairs n [(x,y)]
    | diffTuple(x,y)>= n = addPairs[(x,y)]
    | otherwise = [0]
