Advent of Code 2022

2022-12-01

Let’s do this thing!

I’m going to try Rust this time, since it’s 1) awesome 2) fast and 3) crazy. :D

Let’s see how it goes!

If you’d like to see the full form of any particular solution, you can do so on GitHub (including previous years and possibly some I haven’t written up yet): jpverkamp/advent-of-code

Stateful Solvers and Iterators

2022-10-16

Rust, yet again! Let’s take what we did last time with Solving Sudoku (again) and improve the code structure a bit more.

Goals:

  • Create a ‘Solver’ struct that can maintain state (such as how many states we’ve visited, how much time we’ve spent)
  • Track the above stats
  • Turn the ‘Solver’ into an iterator which will iterate through given solutions (a single call will give the first solution or you can run through the iterator to get all of them)

If you’d like to follow along, I’ve started uploading the code here: https://github.com/jpverkamp/rust-solvers

Lunar Arithmetic in Rust

2022-09-21
I’ve been playing with various languages / language design a lot recently (inspired by my Runelang series). As I tweak and change what I’d like to implement in a language… I kept finding myself coming back to more or less exactly how Rust looks (albeit without the borrowing). So… that seems like a pretty good reason to start picking up some Rust. In another thread of thought, I stumbled upon two OEIS (on-line encyclopedia of integer sequences) sequences: A087061: Array T(n,k) = lunar sum n+k (n >= 0, k >= 0) read by antidiagonals and A087062: Array T(n,k) = lunar product n*k (n >= 1, k >= 1) read by antidiagonals.
