Description: 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 or equal to 1)
and
n! = 1 (for n = 0).
For example, 5! = 5 • 4 • 3 • 2 • 1, which is 120.
a) Write an application that reads a nonnegative integer from an input dialog and computes
and prints its factorial.
