Problem Statement

Write and test a simple method to compute n!, the product of the first n positive integers. Given an integer parameter n, your method should print each number including n, calculate and return n!. For example 3! = 1 2 3 = 6.

Extra credit point if numbers are separated by a comma, 5 numbers per line

Hint: Refrain from using extremely large numbers, I recommend staying under 30. Otherwise, you compiler might take a long time or hang.

Sample output,

- e) to calculate it's factorial 23 1,2,3,4,5, 6,7,8,9,10, 11,12,13,14,15, 16,17,18,19,20, 21,22,23 Factorial of 23 is 862453760
