I didn't get very far into AoC this year as I ran out of time. Maybe I'll pick it up again later. But my point is, I was surprised at how hard day 5, part 2 was. I didn't give up and solved it, but went away wondering whey I'd missed something obvious and overcomplicated it. So it brings some relief to know it was 'supposed" to be a bit challenging!
