Today's #adventofcode really kicked my arse. @ericwastl writes some fiendish puzzles from time to time. This one takes way too long for my solution to run (3+ seconds) so I'm going to have to get my optimisation hat on.

Replying to @dsilverstone @ericwastl
Be proud that you finished it at all - the stats adventofcode.com/2019/stats show it was the hardest one (so far...) by a long way. I was pleasantly surprised to get position 1165 at ~23:00 UTC last night!

Oh I am very pleased indeed. So far I'm managing to do each day on the day, though I got to cheat for a few days when I was in SF :-D
