I was certain that C would really help me with the bit fiddly puzzles, but yesterday kicked my booty and left me slapping together something ugly but functional in Python. I switched over after encountering a realloc bug in my custom hashmap implementation. So. I've got some more studying to do on that front. Hopefully you had a better day.

The Puzzle

In today’s puzzle, we're hanging out with the elves! They're playing a number game that involves remembering the last time a particular number was said and generating an infinite sequence from that. I'm thinking that there may be some tricks learned from past years that may be applicable here, but I'll confirm once I've gone through it and submitted my solution. Good luck!

The Leaderboards

As always, this is the spot where I’ll plug any leaderboard codes shared from the community.

Ryan's Leaderboard: 224198-25048a19

If you want to generate your own leaderboard and signal boost it a little bit, send it to me either in a DEV message or in a comment on one of these posts and I'll add it to the list above.
