Advent of Code 2019 Solution Megathread - Day 16: Flawed Frequency Transmission

Jon Bristow - Dec 16 '19 - - Dev Community

Can't stop the signal!

Day 16 - The Problem

Communication speed and quality has become a problem out here in the gas giants. Communication takes so long that we need to come up with a way to verify and repair the signals we receive to avoid having to have Control repeat itself.

Part 1 has us apply the "Flawed Frequency Transmission" algorithm supplied in the problem statement. We need to run it 100 times to get our solution.

If you brute forced your way through Part 1, Part 2 is a whole lot of hurt. The "actual" signal is 1000 times as long as in Part 1, so once again we need to find a good way to cheat.

Dev.to List of Leaderboards

If you were part of Ryan Palo's leaderboard last year, you're still a member of that!

If you want me to add your leaderboard code to this page, reply to one of these posts and/or send me a DM containing your code and any theming or notes you’d like me to add. (You can find your private leaderboard code on your "Private Leaderboard" page.)

I'll edit in any leaderboards that people want to post, along with any description for the kinds of people you want to have on it. (My leaderboard is being used as my office's leaderboard.) And if I get something wrong, please call me out or message me and I’ll fix it ASAP.

There's no limit to the number of leaderboards you can join, so there's no problem belonging to a "Beginner" and a language specific one if you want.

Neat Statistics

I'm planning on adding some statistics, but other than "what languages did we see yesterday" does anyone have any ideas?
