// This test isn't testing our function -- make it do that in such a way that
// the test passes. Then write a second test that tests that we get the result
// we expect to get when we call `times_two` with a negative number.
// No hints, you can do this :)
pub fn times_two(num: i32) -> i32 {
num * 2
