Complete the following Haskell function definition copies that produces a list of copies of a list. For example, copies 4 [1,2,3] results in [[1,2,3],[1,2,3],[1,2,3],[1,2,3]].
Give a recursive definition. (You can assume n >= 0.)
copies :: Int -> [ Int ] -> [[Int]]
copies 1 xs = [xs]
copies n xs = ________________
