The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
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.

I used the same basic idea in my non-recursive solution. However mine is MUCH slower, probably because it requires a lot of list manipulation that isn't necessary in the recursive approach.

Part 2, on the other hand, was more much complicated. I noticed beforehand that it was unfeasible to simulate every last of the trillions of possibilities, that it was necessary to keep track of the win counters in some other form. But I could not figure out initially how to do it. I looked this thread for ideas, and managed to understand the strategy. Credits go to u/SwampThingTom for the idea ([this comment](SwampThingTom), and the code behind it). After understanding the approach, I implemented it on my code (instead of copy/pasting).

Unofficial AoC 2021 Participant Survey
Nothing other than this year's Advent of Code. Decided to use it for AoC as a way to see what I can do with it.

Part one went fairly fast, but spent quite some time on getting part two right. I settled on the approach of just iterating over the grid and using a boolean to see if I had to count elements or not. However, I had some issues figuring out when to swap, this post by /u/rogual helped me figure it out. After that I lost quite some time on an error that only occurred with my input, not with the example input. It turned out that my loop (which I take form my p1 solution) didn't include the start node, which caused all sorts of counting issues.
