find_factorial

Instruccions

Complete the function factorial to return the factorial of a given number.

As a reminder the factorial of a number is the product of all the integers from 1 to that number.

Example: the factorial of 6 (written 6!) is 12345*6 = 720.

Do not forget the rules for 0 and 1.

Expected Function

pub fn factorial(num: u64) -> u64 {
}

Usage

Here is a possible program to test your function :

use find_factorial::factorial;

fn main() {
    println!("The factorial of 0 = {}", factorial(0));
    println!("The factorial of 1 = {}", factorial(1));
    println!("The factorial of 5 = {}", factorial(5));
    println!("The factorial of 10 = {}", factorial(10));
    println!("The factorial of 19 = {}", factorial(19));
}

And its output:

student@ubuntu:~/[[ROOT]]/test$ cargo run
The factorial of 0 = 1
The factorial of 1 = 1
The factorial of 5 = 120
The factorial of 10 = 3628800
The factorial of 19 = 121645100408832000
