As 2023 Advent of Code is approaching fast, I thought I’d revisit my 2022
entries, and I realised a good focus would be to post one a day during November.
No guarantees as to the quality of the algorithms used, but hopefully people
will find the code readable and interesting. If anyone has questions or ideas
for improvement, I’d love to hear them. They were all written in Dart, and I
will modify each one to allow it to run online in the browser. Some of the code
may look a little odd as I had to inline the functionality from some libraries
that I used as DartPad doesn’t support them all. Anyway, here’s the core of my
response to Day 1. The full code can be read and run by following the link
above. int part1(String lines) => totalCalories(lines).first; int part2(String
lines) => totalCalories(lines).take(3).sum; Iterable totalCalories(String lines)
=> lines .split('\n\n') .map((e) => e.split('\n').map(int.parse).sum)
.sorted(descending);
Hi all,
As many people here may already know, Advent of Code is an annual programming challenge that runs from 1st to 25th December each year where each day a new puzzle is published for you to solve. The puzzles ramp up in difficulty during the month and can test your familiarity with core computer science principles and algorithms.
As the title says, I’m currently going through my entries (written in Dart) to last year’s challenge and rewriting them to run in your browser using DartPad. I’ll be posting one a day until 25th November to the Advent of Code community on lemmy.world.
It’s fairly quiet there at the moment, but I hope that with enough awareness of the community, it will liven up enough over the coming weeks that I don’t have to go back to the other place for interesting discussions and hints next month!
Yes, when I did a search, I found I had a choice between two quite small and inactive communities, so I went for the slightly larger one. I’ll crosspost today’s post to that community see if it stirs up any more interest.
True. I’m certainly at the point where quick jobs that I would have once done in Python quite often get done in Dart instead, avoiding the “context switch” of having to think in Python for that one task.

If you’re posting long videos try to add in some form of tldr for those who don’t want to watch videos
Thanks Chief
Note weve also got an advent of code community that got started up into this instance at !advent_of_code@programming.dev

I love dart, keep up the good work
Yes, I really adopted it due to Flutter, but the dev team really are doing great work to make it a nice language, especially with version 3.
I’m biased because I wrote a backend framework for it, but it’s really good on the backend and even just a general scripting language
