I tried multiple scenarios including negatives and still no luck
I am approaching this in a different way than what has been posted by others. I ran multiple scenarios with no issues, IntelliJ passed the assignment but I couldn't get it to show complete, so I tried to submit it through the web, and it will not pass saying that I need to display the middle number.
