Exercise F
——
Implement a function stack that takes the first element
of a list and moves it to the back
stack List a -> List a
stack xs =
[] --remove this line and implement your halves function here
Exercise G
Implement a function halves that takes a list of integers
and divides each element of the list by two
(using the integer division operator //)
NOTE use the map function combined with a lambda expression
to do the division with a neat solution
halves List Int -> List Int
halves xs =
[] remove this line and implement your halves function here
