Haskell: average x y = (x + y) / 2 sqrt\' :: (Ord a, Fractional a) => a -> Int -> a sqrt\' 0 _ = 0.0
I want to implement a generic hierarchy for tree structures, which can later be used in an implementation-independent way to describe generic algorithms over trees.
Given the below program, I am having issues dealing with monads. module Main where import System.Environment
I asked before what libraries to use in haskell to program a game, and got quite nice answers that got me in the right direction.
