Factorial of a non-negative integer, is multiplication of all integers smaller than or equal to n.
Example : Factorial of 6 is 6 * 5 * 4 * 3 * 2 * 1 which is 720.
We can find the factorial of a number in one line with the help of Ternary operator or commonly known as Conditional operator in recursion.
Factorial of 5 is 120
