Day 20! Only 5 more days after this one! At this point, I've fallen severely behind, but I haven't given up yet. I'm determined to finish by Christmas.

In this challenge, we are enumerating the possible directions we could take while exploring the North Pole, as laid out by a Regular Expression. And this is only the first part! Once we finally have our map built, we have to find the very furthest room from us in the facility.

Hopefully, after completing this challenge, your expression will be one of Christmas joy!
