Question 285
Factorial of a Number
Factorial of a Number
Create a class named FactorialUtil with a public static method Factorial that takes one integer n and returns n! (n factorial): the product of all whole numbers from 1 up to n. By definition, the factorial of 0 is 1. Use a loop to multiply the values together. For example, Factorial(4) computes 1 * 2 * 3 * 4 and returns 24.
Expected Output:
24= newline. The output ends with a newline — print one after the last line.
