Built-in functions on lists. Do in Haskell language using GHCi

(a) Use take and length to define function firstQ :: [a] -> [a] that receives a list as input and returns the first quarter of it. For example, if the input is [1..20] then the output would be [1,2,3,4,5].

(b) Use !! to define function fourth :: [a] -> a that returns the fourth item of the input list.

(c) Use head and tail to define function fourth1 :: [a] -> a that returns the fourth item of the input list.

(d) Use !! and length to define function nthFromLast :: Int -> [a] -> a that receives a number n and a list, and returns nth item of the list from last. For example, nthFromLast 3 [1..7] must return 5.
