I agree. If that is a requirment, it should be listed within the problem statment explicitly imo.

Lol when I wrote my code, I was like somebody going to find a cool way to do this even though it's not hard. Great solution!

As a lover of ternary operators, I love it.

Understandable about readability but super cool.

I like reading the ternaries with the : as elses (else ifs) and the ? as like returns.

This may be clear to lots of people, but I'd drop this for extra perspective incase someone is new or not as comfortable with ternaries.

Happy Coding!
