You're correct. Please, however, use a spoiler tag when sharing code that could lead people to the solution.

use the spoiler flag if discussing code / methods. i have added the flag to your comment

explain why it works)

Can someone clarify something for me?
I did the exact same solution, but wrapped in a if-else statement to verify the true and false returns.

but will the return always be true or false? So no need to wrap in if-else?
Thanks

Very nice and clean. I got very close with my attempt. Cheers from Brazil

It needs to be done manually, done.

solutions that do not pass the current tests - should be removed or marked as outdated. Maybe.

Nice

Thank you! :)

Yes. Read all the other comments.
The kata had a "bug" back then.

This would fail the current set of unit tests.

Because the kata was changed after this was made. See the comments below.
