Write a program that will allow the user to enter three exam scores, find their sum, and, using the Answer(Num1, Num2) function, computes and displays the exam average. Write a recursive function, Factorial(N), which computes and returns N!. Trace the action of the function Factorial(N), similarly to that ofif it is called by the following statement:

Set Answer = Factorial(3)
