I just skipped it to check if there is someone else who finds the question confusing

This one makes absolutely no sense to me. A rewording would be nice.

This was a good challenge. I spent a little bit learning some regex for it.

Figured it was possible with regex but I didn't feel like giving it a go. The other methods are also faster.

A reminder to always have null on the right side of the if statement. It's cleaner and easier to read.
