This was messy. I misunderstood part2, run into some compiler bugs and stack overflows. I am not sure if my solution is over complicated, but it works.

Here is my solution.

Part 1 was quick, part 2 needed some thinking. Not sure if I overcomplicated things.

I'm also pretty sure it will not work for every input. I do not handle the start 'S' correctly on part 2. But since it took me to much time to solve it, I have no desire to fix this.

@Oskar Hahn I think I need some time to understand your solution for p2, but it definetly looks interesting.

Oskar Hahn (Dec 10 2023 at 18:13):

I tried to clean up my solution a bit. I hope it is understandable now.

I also wrote an explanation for the solution of part 2. SPOILER!

Fabian Schmalzried (Dec 11 2023 at 07:42):

Nice explanation, thank you.
