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.

[2023 Day 5 Part 2] Haskell libraries really shine here
I didn't realize Haskell had that. I wrote a similar Scala library for 2022 Day 15 that's basically the encapsulated equivalent of a [Range a], but I really like the API of Haskell's library. Especially Haskell always handles infinite sequences well.

[2022 All Days]
Here's mine. Most of it I wrote in prior years, but refined this year. To account for problem-specific details, the functions are very generic and higher-order. It has a handful of well-known algorithms like A* and Floyd-Warshall, some handy data structures like circular buffers and intervals, and some type classes that are useful for parsing puzzle input.

I wrote an immutable A* in Scala a few years ago. It's not too bad if you have immutable hash maps and an immutable priority queue. Comes in handy for a lot of puzzles.

[2022 day 4] My experience in a nutshell
Last year I made myself an input parsing library that was really nice for this problem. I just create a Pair class with 4 number members, then ask for a List[Pair] and it knows what to do. My solution.

Best immutable priority queue for scala
I implemented my own using a pairing heap. It sped up my immutable A* considerably, but I was just using minBy on a List before that. Inserts are amortized O(1) and delete-mins are O(log n).

What is the best way to read a text file of your input in your language of choice?
This year I'm creating a Scala library to make it easier. I specify a type like List[Int] and it summons the correct type classes to parse it into that format for me.

Part 1 straightforward implementation. Treat it as a graph and just follow the instructions.

Part 1 -> simple implementation, sort the list using a custom function. The main component is the function extractInfo which returns the number of pairs and the number of times the card with the most duplicates appears.
