Write a function that takes two lists of integers and returns a list containing tuples with corresponding elements from both the lists. For example - f ([1, 2, 3], [4, 5, 6]) -> [(1, 4), (1,5), (1,6), (2, 4), (2, 5), (2, 6), (3, 4), (3 ,5), (3, 6)]. If either list is null, the result is null. The lists do not have to be the same length. Solve this using recursion. You may NOT use the length() function or lambda() function or comprehension lists to do your solution. Solve it with Haskell and Scheme.
