I have the same problem. Mine works on Code Pen but fails the test. Maybe it's because of type conversions, but it wasn't stipulated that we don't do so.

Thank you

Read this: https://docs.codewars.com/training/troubleshooting and I see a php solution published in javascript.

Im not sure about the format. I inputted working code. I have the program running in Visual Studio. But the "TEST" says it's wrong.
