on the first day* of christmas, techbros gave to me: a product that would unlaunch promptly!
*just imagine we are in a world line where the days of Christmas start today, I guess

Bonus content: the OP that got purged had crossposted this to a couple places, let’s start some beef on the fediverse?
These link to the same thread, thanks to the magic of lemmy: lemmy.world link, awful.systems link
I actually have a shrimp torture farm. It brings me infinite joy. However its running costs are quite high and I require donations to keep it going
JFC. Thank you so much for this.
Thinker? Debatable. Computer scientist? LOL
Ah, finally, a paper article to pin to my Roko’s basilisk/David Gerard/X Æ A-Xii red yarn corkboard

It's one AOC problem zogwarg, what could it cost? 10 PB?
But actually, real internet truthers know that the above is a revisionist version of history put forth as a psyop by russian troll farms, in addition to inventing AI chatbots and adding fluoride to water. This is all to weaken and feminise western men and turn them communist.
The evidence? owo actually comes from the Russian word "хорошо", meaning "good" or "ok", and its usage is normalising russian language in today's tiktok-pilled youth. This was a strategy cooked up by known cult leader Rajneesh, of course known in Russia as Ошо. Of course, uwu comes from the Russian word "Ушу" which is a secret programming command for the proletariat to learn Wushu and other forms of chinese/communist martial arts so that people can rise up and seize the means of production.

So my understanding is that uwu/UwU originates as a kaomoji, think (^.^) and (O.O) etc. Using the 'w' character to render the mouth starts as a furry thing or a general projection of human expression onto common animals like cats or dogs. (You'll see the omega symbol used in examples as well.)
Over the last 20-30 years or so of online interaction etc. kaomoji start to gain a sort of cringe notoriety alongside RP chatting, culminating in a few catalysing memes/copypastas.
Eventually "owo" and "uwu" start being read aloud/vocalised, similar to how people starting saying "lol" out loud, and this is associated I guess with a cutesy sort of image, though that image is often corrupted or subverted- for example e-girls, who co-opt a lot from of gaming and anime subcultures, lean into the uwu of it all.
followup
So memoisation is predictably needed for part 2 to run in time. It's an O(e^n^), so it takes seconds by step 39 and minutes by step 47.
Day 11!
discussion p1 + 2
I'd say this was pretty easy. My instinct was that 64 bit ints were big enough for this problem, and that memoising would also be a good idea. I didn't experiment with a control though, so I don't know if memoisation was truly necessary. Either way, my initial solution for 1. was performant enough for part 2.
Day 12:
P1
Ok. I have been traumatised by computational geometry before, so I was initially spiralling. Luckily, there wasn't too much comp geo stuff to recall.My solution was a lot simpler than I initially thought: no need for union-find, accounting for regions inside regions, etc. Just check every square for a given region, and if it touches a square in the same region that you've seen before, subtract the common edge. This is linear in the area of the problem, so it's fast enough.
P2
It took a moment to figure out that I could modify the above perimeter counting to mark the squares containing the perimeter and walk along it afterwards, counting each edge. This is also linear in area.
