Is the "1" i highlighted a typo test with map2[((*)2), ((+)2)] [4,3] yields [8,5]. it worksfine */ listReverse :: [Int] -> [Int] -> [Int] listReverse [] temp = temp listReverse (head : tail) temp = listReverse tail (head: temp) map2helper :: [ Int->Int] -> [Int] -> [Int]-> [Int] map2helper [] [] temp = temp map2helper (head : tail) (p : q) temp = map2helper tail q ( (headp) : temp) map2 :: [ Int->Int] -> [Int] -> [Int] map2 l m = (listReverse (map2helper l m []) [] )
