• Advent of Rust // Day 11

  December 15, 2022 //

  #adventofcode #rust

  I love that each Advent of Code reminds me at one point that I never paid much attention in math class. Part one of day 11 was, as usual, straightforward. With the divider gone and the number of rounds up to 10.000 in part two, I knew I was fucked. continue reading

• Advent of Rust // Day 9

  December 13, 2022 //

  #adventofcode #rust

  I finally had some time to review day 9. For some reason, I didn’t get the logic behind the knot movement in part two. So I had to break it down into tiny steps to get to my “duh” moment. continue reading

• Advent of Rust // Day 10

  December 11, 2022 //

  #adventofcode #rust

  After taking a day off, I’m a little behind. For some reason, I can’t wrap my head around part two of day 9, but fortunately, day 10 was easy again. continue reading

• Advent of Rust // Day 8

  I’ll just leave it here without further comment. continue reading

• Advent of Rust // Day 7

  December 7, 2022 //

  #adventofcode #rust

  I spent this morning trying to build a super generic directory tree structure using dynamic types and ended up being frustrated because I don’t get how ownership, lifetime, and all that jazz works in Rust. continue reading

• Advent of Rust // Day 6

  December 6, 2022 //

  #adventofcode #rust

  Easy one. I still haven’t figured out why Rust sometimes can not infer types, like with the hash set below. continue reading

• Advent of Rust // Day 5

  #adventofcode #rust

  Today’s puzzle was another one where the solutions for the two parts differed only in a minuscule detail. continue reading

• Advent of Rust // Day 4

  December 4, 2022 //

  #adventofcode #rust

  The plural of regex is regrets, some people say, but I like ‘em. Not for everything and all the time but they come in handy for some tasks. continue reading

• Advent of Rust // Day 3

  December 3, 2022 //

  #adventofcode #rust

  I was surprised there’s no built-in way to find the intersection of multiple sets. I started to implement a function for this, but quickly discarded it in favor of a more specific one for the task at hand. After all, there’s exactly one character to find for each bunch of strings. continue reading

• Advent of Rust // Day 2

  December 2, 2022 //

  #adventofcode #rust

  The second day was still easy on the puzzle side. I guess I went a little overboard with the implementation, but I wanted to play with the language. I had a lot of first ones today: First struct, first enum, first use of impl to add functionality, passing functions as arguments, and adding behavior with derivable traits. continue reading

• Advent of Rust // Day 1

  December 1, 2022 //

  #adventofcode #rust

  Today is December 1st and thus the first day of Advent of Code. This year I decided to give Rust a try. As with my attempt with Haskell two years ago, I come unprepared with virtually zero knowledge about Rust. The only things I did beforehand were install the Rust compiler, the IntelliJ Rust plugin, and run the canonical “hello world” program. continue reading
