[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.

Advent of Code (in MiniScript), Day 18
Welcome back to my series of Advent of Code solutions in MiniScript! Day 18 was pretty straightforward, though it presents some interesting choices in how to represent the data -- choices I'm not sure I made optimally.

Late bloomers (that started life closer to 30), how are things going for you?
And I've solved all of the Advent of Code problems so far this year, which is utterly unimportant but still brings me joy.

Coding/programming is absolutely fantastic
If you'd enjoy some coding challenges, advent of code (https://adventofcode.com/) is currently going on.

Advent of Code (in MiniScript), Day 17
Welcome back to my series of Advent of Code solutions in MiniScript! In Day 17 we got to (sort of) play Tetris. Five different Tetris-like shapes fall into a pit, moved left or right on each step according to the input. The first task is to see how high this stack will grow after 2022 blocks have been dropped in.
