until I tried matching from right to left instead :3
My intuition nudged me there but I couldn’t reason how that would change things. You still have to test the remaining string, and its remaining string, backtrack, etc right?

It was just a hunch that the inputs were generated to be difficult to parse using a naive algorithm (ie the towels have a lot of shared prefixes). In general I don’t think there’s any reason to suppose that one direction is better than the other, at least for random inputs.
