# Advent of Code 2023
This repository contains my solutions for the [Advent of Code 2023](https://adventofcode.com/2023) challenge.
## Language
I am using C# for this year's challenge. I'd consider myself proficient in C#, but on a day to day basis I don't use it as much and would just like to get more practice with it.
## Structure
Each day's solution is contained in a separate folder. Each folder contains:
- A `PROBLEM.md` file containing the problem description.
- A `INPUT.txt` file containing the input for the problem.
- A dotnet console application containing the solution.
- An xUnit test project containing unit tests for the solution.
### Prerequisites
- [.NET 8.0](https://dotnet.microsoft.com/download/dotnet/8.0)
### Running the Solutions
To run the solutions, navigate to the solution folder and run the following command:
```bash
dotnet run --
```
Or for part 2 solutions
```bash
dotnet run -- part2
```
You can also build the projects and run the executables directly.
```bash
dotnet build
./bin/Debug/net8.0/
```
## Challenges
| Day | Problem | Solution | Status | Notes |
| --- | -------------------------- | :--------------------------------------: | :----: | ------------------------------------------------------------------------------------------------------------------------------------------------ |
| 01 | [Problem](./01/PROBLEM.md) | [Solution](./01/Trebuchet/) | ✅ | The trickiest part here was accounting for overlapping digit words. |
| 02 | [Problem](./02/PROBLEM.md) | [Solution](./02/CubeConundrum/) | ✅ | The key to me here was to parse the input into a useful model. |
| 03 | [Problem](./03/PROBLEM.md) | [Solution](./03/GearRatios/) | ✅ | The edge case that got me here was lines ending with a part number. |
| 04 | [Problem](./04/PROBLEM.md) | [Solution](./04/Scratchcards/) | ✅ | Part 2 gets out of hand quickly with just 200 cards. |
| 05 | [Problem](./05/PROBLEM.md) | [Solution](./05/IYGASAF/) | ✅ | I brute forced part 2 using parallelism. I know shame. |
| 06 | [Problem](./06/PROBLEM.md) | [Solution](./06/WaitForIt/) | ✅ | Thank goodness part 2 was not like 5's part 2. 😅 |
| 07 | [Problem](./07/PROBLEM.md) | [Solution](./07/CamelCards/) | ✅ | What took me longest here was I missed a case when jokers are wild and there are three groups of cards. |
| 08 | [Problem](./08/PROBLEM.md) | [Solution](./08/HauntedWasteland/) | ✅ | Got to implement a least common multiple algorithm for part 2. |
| 09 | [Problem](./09/PROBLEM.md) | [Solution](./09/MirageMaintenance/) | ✅ | Part 1 took me unnecessarily long. The bug was summing a line to check for all zeros is bad idea when negative numbers are involved. |
| 10 | [Problem](./10/PROBLEM.md) | [Solution](./10/PipeMaze/) | ✅ | So...my solutions are rather slow, but they work. Part 2 appears to have a mathematical solution, but scanning is what I came up with on my own. |
| 11 | [Problem](./11/PROBLEM.md) | [Solution](./11/CosmicExpansion/) | ✅ | Expanding the universe was fine in part 1, but part 2 showed I actually needed to calculate the expansion instead of expanding the input. |
| 12 | [Problem](./12/PROBLEM.md) | [Solution](./12/HotSprings/) | ✅ | This one stretched my skills. I needed lots of help from the interwebz. |
| 13 | [Problem](./13/PROBLEM.md) | [Solution](./13/PointOfIncidence/) | ✅ | This solution is the one I think I'm most proud of so far. |
| 14 | [Problem](./14/PROBLEM.md) | [Solution](./14/ParabolicReflectorDish/) | ✅ | Cycles and a cache...that's all I'm going to say. |
