Advent of Code

My solutions to the Advent of Code puzzles.

2023 (Rust)

My favourite days:

• 5
• 7

2022 (Python)

My first "live" AoC. I skipped day 19 because I am too lazy to solve yet another backtracking problem.
Day 16 gave me such a headache that I had to skip both 16 and 17, but I went back to them shortly afterward.

2021 (Python)

Going to finish this, sooner or later.

2020 (Rust)

Second AoC solved at 100%. Left day 20 for last (yet another backtracking problem) but in the end it was easy to solve.

2019 (Rust)

I proudly skipped every day with an Intcode problem. In the end I really enjoyed them.
The day I'm most proud of is day 18, which I solved without consulting Reddit and runs in 6ms total.
Other days I liked:

• 6
• 13
• 14
• 15
• 20
• 24

2018 (Rust)

Third AoC solved at 100%.

2017 (Rust)

Fourth AoC solved at 100%, with the best animation so far.
My favourite days:

• 9 funny parsing
• 12
• 21 reminded me of 2020/20
• 24
• 25

2016 (Rust)

Finally, I know why The Easter Bunny is on the Naughty List.
The first part of day 11 was a pain, but the second part was the easiest second part ever.
My favourite days:

• 13 an easy BFS after the infamous day 11
• 20
• 22 the first time I solved a problem by hand (second part)

2015 (Rust)

First AoC solved at 100%. I took the opportunity to improve my Rust. I am proud of this one.
