C#/Csharp: Code here

rewrote it as a pair of linq oneliners (sort of, if you ignore parsing, like that's the one thing I wish C# could do better: read ints from files) https://github.com/Bpendragon/AdventOfCodeCSharp/blob/0800b/AdventOfCode/Solutions/Year2022/Day04-Solution.cs

Part one went fairly fast, but spent quite some time on getting part two right. I settled on the approach of just iterating over the grid and using a boolean to see if I had to count elements or not. However, I had some issues figuring out when to swap, this post by /u/rogual helped me figure it out. After that I lost quite some time on an error that only occurred with my input, not with the example input. It turned out that my loop (which I take form my p1 solution) didn't include the start node, which caused all sorts of counting issues.
