[Haskell-cafe] defining mapPairs function

Hello, I just came across with this question on the exam and can not think of implementing it. mapPair :: (a -> a -> a) -> [a] -> [a] such that mapPairs f [x1, x2, x3, x4...] = [f x1 x2, f x3 x4,...] and if the list contains an odd number of elements, the last one is kept unchanged, for example mapPairs f [x1, x2, x3] = [f x1 x2, x3] Any ideas will be appreciated, thanks -- View this message in context: http://www.nabble.com/defining-mapPairs-function-tf4350356.html#a12395628 Sent from the Haskell - Haskell-Cafe mailing list archive at Nabble.com.
