Write a function that takes an `int` min and an `int` max as parameters. That function returns a slice of `int`s with all the values between min and max.
Write a function that takes an `int` min and an `int` max as parameters. The function should return a slice of `int`s with all the values between the min and max.
Min is included, and max is excluded.
If min is superior or equal to max, a `nil` slice is returned.
If min is greater than or equal to max, a `nil` slice is returned.
