One could instead count |F7 (that's what I do in my refactored solution), but counting all the bends would miscount the vertical segments (FJ would end up canceling itself out).

That sounds like what I suggested here, actually. I don't have anything in my library with quite the right API yet, but I already have most of what you describe coded out. (It looks like I whipped it up for 2017 Day 13.)

It doesn't, but you can use a separate list, wrapper classes, and deque.index to find where the values live. I may be biased but I think that my solution (ultimately using deque) isn't as complex as a custom linked list.

Part 2 assumes you did part 1 properly. I did not! I'm pretty sure that the intended solution is to do a sort of reverse search (have a target number of geodes and work backwards to see if that's possible to achieve) but I was just not having success coming up with a way to do that. It's probably going to be blindingly obvious once I figure it out, but that might be an exercise for tomorrow.
