Advent of Code is an Advent calendar of small programming puzzles for a variety of skill sets and skill levels that can be solved in any programming language you like. People use them as a speed contest, interview prep, company training, university coursework, practice problems, or to challenge each other.

Solving times

I started participating in 2020. I have, since then, also solved others. Furthermore, living in the Netherlands, and being a night owl, getting myself behind a screen at 6:00 (local time) is hard. Nevertheless, I solved some of them within an hour. All results can fe found here: Solving.md.

Lines of Code (LoC)

When a measure becomes a target, it ceases to be a good measure. We all know it to be true, so keeping track of the lines of code per puzzle is questionable, nevertheless, I do: LoC.md.

Note that comments, whitespace, namespace declarations, main class declarations, and lines only containing brackets or attributes are ignored.

Durations

Another measure that should not become a target (but secretly is): durations. An overview of my results can be found here: Durations.md.

Unit test driven

All puzzles can be run as unit tests. To reduce plumbing code I've extended on NUnit. All puzzles have the following template:

namespace Advent_of_Code_@Year;

[Category(Category.SomeCatagory)]
public class Day_@Day
{
    [Example(answer: 666, "Short Example")]
    [Puzzle(answer: 666, O.μs10)]
    public long part_one(string str)
    {
        throw new NoAnswer();
    }

    [Example(answer: 666, "Short Example")]
    [Puzzle(answer: 666, O.μs10)]
    public long part_two(string str)
    {
        throw new NoAnswer();
    }
}
