This is a fair assessment. This is really just a "harder" take on the same problem that accounts for some very common edge-cases. Personally, I've seen enough "Code Golf" 30-character solutions to these 7 kyu problems and wanted to provide a different perspective. We're all just here to learn, and I believe this solution provides an opportunity to learn that isn't as common here on CodeWars.

It's bad. The programmer assumes things which you should never do. This solution is vastly less performant because of that. It should only be transfored to this when the actual implementation calls for this change, never sooner.
