You must assign the grades for a programming class. The class is studying recursion, and students have been given this simple assignment: Write a recursive function SumSquares that takes a pointer to a linked list of integer elements and returns the sum of the squares of the elements.

Example:

SumSquares(listPtr) yields (5 * 5) + (2 * 2) + (3 * 3) + (1 * 1)
= 39 Assume that the list is not empty.
You have received quite a variety of solutions. Grade the functions that follow, marking errors where you see them.
