Same! I accidentally optimized part two out of my part one solution so I just had to remove a check and replace my visited set with a list.

I had the same problem with part two that I had with part one. My test was passing but my input was failing. I missed that you can only move the values to free memory on their left. It was a single line fix but I lost a lot of time losing my mind.

Day 8 should be pretty quick for you but don't get caught up reading the description of the problem. The text is very confusing but the examples given make perfect sense.

Lol nevermind, my optimization gave a different answer.

I found a nicer way to detect the loops by /u/rkechols by tracking the position and the direction in my visited Set but my original method was to just use a counter and check if it got to over 10000.

Yeah that was my first year doing it in real time and it was pretty intense. I made it through day 15 before I stopped but I had a few prior days I didn't finish.
