Factorial is a multiplication operation of natural numbers with all the natural numbers that are less than it. If efficiency is not a concern, computing factorials is trivial from an algorithmic point of view: successively multiplying a variable initialized to 1 by the integers up to n (if any) will compute n!, provided the result fits in the variable. What is Factorial? Factorial of 5 is 120. And, the factorial of 0 is 1. Examples: 1!
