What is #Factorial of a Number?

The factorial (denoted by n!) for a number (say n) is the product of all the numbers preceding n with the number itself.

!n = n * (n - 1) * (n - 2) * . . . * 2 * 1

For example,

!6 = 6 * 5 * 4 * 3 * 2 * 1 = 720

!12 = 12 * 11 * 10 * 9 * 8 * 7 * !6 = 479, 001, 600

We can say that,

!n = n * !(n - 1)

Important points-

Factorial of 0 = 1

Factorial of negative numbers does not exist.
