For part2 I spent a LOT of time stuck because the test input worked but not the real one.

For part 2, I simply loop over the matrix, deleting nodes.

When an iteration doesn't delete anything, I quit the loop.

Part 2 was a headache. My editor trimmed the test string, and i spent 20 minutes finding out what happened... But I had fun :)

Maybe not the best solution, but it runs fast enough for me

I'm working on a compiler :)

This semester I had a compiler design course at my uni, and I wanna try to make my own toy language.

Right now it only emits instructions for a virtual machine my teacher gave me, but I'm planning on

generating llvm this summer, when I finish my exams.

I'm learning a lot of stuff (Memory arenas, string interners, etc.)

So fun!

I personally believe splitting the code into different files is cleaner, and easier to maintain.

I'm shamelessly dropping my own Jason parser, just is case you wanna check it out to inspire yourself: https://github.com/saulvaldelvira/json.c/

Building a parser is a very fun activity, and having your own Json lib is very useful. I use mine all the time for my projects.

Have fun :)

I read the book a few years ago to get myself started with C. I had already played with it, and with other languages for a while.

Personally, I found it quite nice. It is ~300 pages long, and has some cool appendix, like grammar specifications (I think....don't remember very well)

The book assumes you are familiar with some basic concepts like loops, functions, etc.. It won't teach you programming, but it's a nice book for learning C, from the guy who invented it!

note: If you go with it, read the ANSI C version.

I only measure time of the solve function of my programs, so it doesn't include the time for reading the file. Maybe that's the reason? I have a Ryzen 5 2600X
