In mathematics, the factorial of a strictly positive integer x
, denoted as \(x!\) is the product of all strictly positive integers less than or equal to x
. The factorial of 0 is defined as 1. Calculate the factorial of an integer x
and store the computed value in the variable result
.
Examples:
- \(5! = 5 \times 4 \times 3 \times 2 \times 1 = 120\)
- \(0! = 1\)
