For example, 5! = 5 · 4 · 3 · 2 · 1, which is 120. Use while statements in each of the following:

The factorial of a nonnegative integer n is written n! (pronounced “n factorial”) and is defined as follows: n! = n · (n – 1) · (n – 2) · ... · 1 (for values of n greater than 1) and n! = 1 (for n = 0 or n = 1). a) Write a program that reads a nonnegative integer and computes and prints its factorial. b) Write a program that estimates the value of the mathematical constant e by using the formula: Prompt the user for the desired accuracy of e (i.e., the number of terms in the summation).
