Hello, Rachel Wedemeyer. I guess you might still be developing this Problem?   There are a few important improvements that you will need to make. One of the most important is to ensure that you include several (at least four) tests within your Test Suite, each for a different set of inputs.   You can find some more thoughts on these matters at Problem 44521.   Lastly, it is worth checking what Problems have already been created, so that yours will be adding something new to Cody's collection. As your current Problem Statement more-or-less duplicates Problems 8, 1046, 1736, I suggest modifying your Problem to create a new challenge for Players.  Regards, DIV.
