pppery

I did it by hand without any visualizations and got rank 104

indeed, it was. It took me ~1h for part 1 and ~1.5h for part 2

I used cached recursion for day 11 (the stones that replicate themselves) as well

All I needed was to wrap my recursive function in a cache and then it was fast

Today felt much easier than a day this close to Christmas should be

(ignore me, I was an idiot - my puzle answer is 85 thousand something so that's definitely a coincidence)

Which is suspiciously the same as the thousands digit in my puzzle answer

Your code overcounts by 8 on my puzzle input

1001 points? It's only 1000

odd

Done 319/247

Why did I suddenly global score when I wasn't before? This problem doesn't seem that different from the others.

Done 55/32

It didn't help that the resulting lineup looked very different from my intuitions about what it would be

@emanresuA And a positive integer solution

I actually found part 2 interesting once I got it - there's a certain class of problems that trivially have no solution (which annoyingly did not include any of the test data but did include some of the puzzle input), and aside from that I found the approximate magnitude of the number of times each button needs to be pressed and just brute-forced

502/2295

I knew I could have used some kind of algebra system, but I did an ugly normal approach that took an hour but worked. Sigh.

(AoC starts at midnight my time and I usually stay up for it but this was hard enough that I gave up, and then thought of the answer while I was in bed)

Hence the ridiculous pairing of 565/17874

This was the first P2 that I had to sleep on before solving

I feel like advent of code is easier than I expected overall this year, but maybe the hard problems are yet to come

I wonder where they can fit 279 trillion stones, though

Apparently my code times out on TIO, even though it finished within the amount of time I was willing to wait on my own (fairly slow) computer

tio.run/…

No

I didn't do even that and it took noticable but reasonable time

and did the same for p2

I did the same (except I implemented it recursively)

but I see plenty of optimizations possible

Mine too

The puzzle text could state that more clearly, though

And I got my best rank so far

but I got it right first try so maybe it wasn't

I didn't like part 2 today - it felt like the correct answer was ambiguous

Unfortunately by debugging won't help you here - I made a stupid logic error which doesn't generalize

Today inexplicably took me an hour and multiple wrong answers for both parts. I guess I'm not as good at making diagonal lists as I thought I was

(but at least I did that after I got the right answer)

I spent 10 minutes debugging what turned out to be my regex for part 2 not matching newlines

Because I'm still getting sporadic internal server errors

I think this day may end up being voided and worth no points

Done 623/411

Just try reloading the page

I had the same problem

me too

Could have gotten 600ish on part 2 except I had to wait 5 minutes for inputing too many wrong answers

Done 232/755

Yeah, that's a little unclear. They do help you by drawing it so z is vertical, though

And first P2 where the answer isn't several trillion or more since Day 17

Agreed
