MyReverse.hs

myReverse :: [a] -> [a]
myReverse = undefined  -- write this

Implement myReverse without using the built-in reverse.

Reference 
myReverse :: [a] -> [a]
myReverse = foldl (flip (:)) []

Fold left over the list, consing each element onto the front of the accumulator as you go — by the time you reach the end, the accumulator is the list in reverse.
