Functional Programming with Scheme

Write a Scheme function named unzip that takes one argument that is a list of two-lists. It returns a list of two list, the first containing all of the first elements of the input tuples and the second with all of the second elements. Here are some example calls and their outputs: > (unzip '()) (()()) > (unzip '(1 x)) ((1) (x)) > (unzip '(((1 x) (2 y) (3 z))) ((1 2 3) (x y z))
