Note: If you fail to use recursion or fail to name your recursive function factorial or Factorial, you will get a score of .

Input Format

A single integer,  (the argument to pass to factorial).

Constraints

Your submission must contain a recursive function named factorial.
Output Format

Print a single integer denoting .
