This is the second time I've seen this problem... and alas, it was no easier the second time. This one definitely had my brain rotating!
I LOVE LOVE LOVE these puzzle/game type challenges. So cool to see the creative ways that Alteryx can extend beyond just the day-to-day job (even if the day-to-day job also feels quite a bit like playing a game most days!)
After using Alteryx for like a week i wanted to try something different then my normal data and these puzzles are pretty fun to play around with and learn something new by doing them.
But after looking at the other solutions i have to say that i should better learn all the Tools that are available instead of using 4 Tools for a function that one can do.
