Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

-🎄- 2021 Day 24 Solutions -🎄-
For a full write-up, see this repo, and for a non-annotated solution, see:
-
-🎄- 2021 Day 18 Solutions -🎄-
Otherwise, the main way I solved this was with a flat list of tokens rather than a truly nested structure. This was very similar to last year's Day 18, which I also solved in a similar manner.

First 2D one! Got to reuse my InfiniteGrid class, which made this much easier.

How to beat AOC 2019, day 13, part 2?
Mine only took about 2 minutes when I originally recorded it. I've since added some optimizations to my Intcode computer, and re-running my original program with the optimized computer now runs in about 45 seconds. 😁
-
[2015 Day 19 (Part 2)] I don't want specifics, but can someone point me in which direction I should work this problem?
Here is my solution in JS, which also has a long comment explaining the main iterative loop.
-
[2020 - Day 15 - Part 1/2] [JS/Python] - Why is the Javascript solution so much faster?
Your solution is very similar to mine, and I too found that using an Array of a set size was way faster than an ordinary Object. I believe it has to resizing the array / object.

Here's the relevant extract from my (recursive) solution. Full code on GitHub.

-❄️- 2023 Day 8 Solutions -❄️-
Like others, I used lcm. Here's an extract of the solution, omitting parsing and main(). Full solution on GitHub.

-🎄- 2022 Day 14 Solutions -🎄-
Solutions to parts 1 and 2 nearly identical and pretty much worked first time. Nothing clever here. This was far simpler than I thought it would be. I probably spent most time trying to think of a mathematical way of getting all points between p1 and p2. In the end, I just constructed two ranges. Full code here.

-🎄- 2022 Day 9 Solutions -🎄-
The core of my solution below using numpy (because I'm learning it!). See github for full code.
-
-🎄- 2022 Day 8 Solutions -🎄-
Python 3 solution using numpy. I got held up because I assume (but know better) that numpy arrays are [x,y] instead of [row, col], which is [y,x].
-
-🎄- 2021 Day 14 Solutions -🎄-
Below is the new solution, which works for part 1 and 2. The full code is on GitHub.
-
-🎄- 2021 Day 11 Solutions -🎄-
These are the key functions. The whole code is on GitHub
-
-🎄- 2021 Day 9 Solutions -🎄-
Part 2 (extract shown below) was a matter of starting with the low points found in part 1 then recursively looking around for relevant points. Full code on GitHub

-🎄- 2021 Day 8 Solutions -🎄-
