This may "work", but it does not do what the challenge asked.

The challenge asked that the function return the result. It did not ask that it print anything.

Also, your processing seems to be checking for a more specific condition than just an overlap. You'll need to simplify your test slightly for this task. Did you peek at someone's answer for task 2?
