Write a tail-recursive Prolog procedure daff2(L,R) to compute the following L

Write a tail-recursive Prolog procedure daff2(L,R) to compute the following L is a list of ordered pairs of the form (a, b) where a and b are integers R contains the result when we add up all the i's where u = (b-a) for all the ordered pairs in the list L For example Given L = [(4,6), (3,4), (5,4)] R-(6-4) (4-3) (4-5)21 1 Why is the program in (a) more eficient in terms of space than an alternative program that is not tail-recursive
