### Instructions
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 1 \* 2 \* 3 \* 4 \* 5 \* 6 = 720.
Do not forget the rules for 0 and 1.
### Expected Function
Create a **function** named `factorial` which returns the factorial of a given number.
```rust
pub fn factorial(num: u64) -> u64 {
}
```
