The factorial of a number n is the product of all positive integers less than or equal to n. Can you help calculate the factorial of a number?
In what concerns the continuous evaluation solving exercises grade during the semester, you should submit until 23:59 of October 25th
(this exercise will still be available for submission after that deadline, but without counting towards your grade)
[to understand the context of this problem, you should read the class #03 exercise sheet]
In this problem you should submit a function as described. Inside the function do not print anything that was not asked!
The name of the .py source file you submit to Mooshak should NOT start with a digit (you will get an error if you submit it like that).

Write a function factorial(n) that, given an integer n, returns its factorial.
The following limits are guaranteed in all the test cases that will be given to your program:
| 0 ≤ n ≤ 50 | The integer whose factorial you need to compute |
| Example Function Calls | Example Output |
print(factorial(0)) print(factorial(5)) print(factorial(12)) |
