I find it hard enough without restrictions (especially toward the end) so I'm not doing anything too wild, but I've been trying to solve quickly this time. My goal was to get in the top 100 on one of the days to actually get a point, but I think I missed my window where the problems got too hard for LLMs but were still doable quickly for me. At least I managed a 136 which is much better than I've ever done before.

Maybe next year I'll actually prepare some utility code for parsing grids and 2d vector math and such.
