Advent of Code 2019 Solution Megathread - Day 10: Monitoring Station

Jon Bristow - Dec 10 '19 - - Dev Community

No IntCodes today, just too many asteroids.

Day 10 - The Problem

We home in on the distress call to find the elves trying to find the best place to monitor the asteroids. Of course we need to stop and help them, as this is our best chance of getting through the asteroid belt in one piece.

Part 1 has us scanning for a new monitoring station location, optimized for the best view of the spinning rocks.

With slopes and distances safely under our belt, the elves decide to just blow everything up. Part 2 is doing some calculations to settle a bet on the results of their spinning asteroid destruction laser beam.

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?

Languages Seen On Day 09
  • javascript x 3
  • python x 3
  • c
  • clojure
  • kotlin
  • ruby
  • swift
Completion Stats

By applying a best-fit descending power trend-line to the 1 and 2 star columns on the stats page, my estimates predict:

2 stars on day 25: 6358 people

1 star on day 25: 420 people. Nice

If you're still going, take heart in that you are in a rapidly dwindling pool of people.

Doing other questionable statistics gives me: 415/6248
