yeah into your browser

also soon enough I'm also going to have to be on mobile so that's gonna be useful

slate zephyr Dec 11, 2023, 1:38 PM

What is cards.values()?

bold coral Dec 11, 2023, 1:38 PM

#

slate zephyr You can do that on mobile? :o

... Yes?

#

Huh
You definitely could until the UI rework

#

Can't find the button anymore

#

Woop

hazy abyss Dec 11, 2023, 1:39 PM

#

slate zephyr What is cards.values()?

so if I have [5 4 3 4 T] it's gonna be in a unordered way [2, 1, 1, 1]

#

it's just the sums of the cards

slate zephyr Dec 11, 2023, 1:40 PM

#

Shouldn't you dedupe that?

bold coral Dec 11, 2023, 1:40 PM

#

That's my groups.len()

hazy abyss Dec 11, 2023, 1:40 PM

#

no need

bold coral Dec 11, 2023, 1:40 PM

#

slate zephyr Shouldn't you dedupe that?

No, it's the count of different card faces

#

2 of X, 1 of Y, etc

#

2 1 1 1 is One Pair

hazy abyss Dec 11, 2023, 1:40 PM

#

also it's a iterator and dedupping that would allocate for no reasons

slate zephyr Dec 11, 2023, 1:41 PM

#

Hmm
I'm getting confused at how you're checking if the len is 4 but then the value is 2 in the match

hazy abyss Dec 11, 2023, 1:41 PM

#

so hashmap, it has length of how many entries there are

#

if there is 2 entries I get the closest entry and see if it's a number that matches to a number a hand type must have

slate zephyr Dec 11, 2023, 1:42 PM

#

Oh hey I sent my day 7
Neat

hazy abyss Dec 11, 2023, 1:43 PM

#

if there is 3 entries you do the same thing, but if one of the numbers overlap I make sure to get another entry and check on it since I know it can't overlap then (TwoPair can only have 1 non-pair)

slate zephyr Dec 11, 2023, 1:46 PM

#

~~So what's the issue again?~~

hazy abyss Dec 11, 2023, 1:46 PM

#

the number is wrong

#

too low

#

well

#

it's actually close enough to not tell me if it's too low or not

#

the example is correct

slate zephyr Dec 11, 2023, 1:47 PM

#

Then it feels like the evaluator is still wrong?

hazy abyss Dec 11, 2023, 1:47 PM

#

which is?

slate zephyr Dec 11, 2023, 1:47 PM

#

The hand one

hazy abyss Dec 11, 2023, 1:48 PM

#

there is nothing to indicate it being wrong

#

the example has these cases

#

it would fail if they weren't checked

#

0 OnePair [3 2 T 3K] 765
1 TwoPair [K T J JT] 220
2 TwoPair [K K 6 77] 28
3 ThreeOfAKind [T 5 5 J5] 684
4 ThreeOfAKind [Q Q Q JA] 483
6440

#

clearly it can handle ThreeOfAKind and TwoPair correctly

#

ah there might be something

#

there is overlap with 1

slate zephyr Dec 11, 2023, 1:50 PM

#

I don't see a full house here, did you add it?

bold coral Dec 11, 2023, 1:54 PM

#

Why is it 1 | 3

hazy abyss Dec 11, 2023, 1:54 PM

#

wait that doesn't makes sense

bold coral Dec 11, 2023, 1:54 PM

#

Shouldn't it be 2 | 3

hazy abyss Dec 11, 2023, 1:54 PM

#

so it wasn't that case

#

so it's just FullHouse??

#

argh]

bold coral Dec 11, 2023, 1:54 PM

And shouldn't four of a kind be 1 | 4

slate zephyr Dec 11, 2023, 1:54 PM

bold coral Dec 11, 2023, 6:05 PM

#

makes sense

#

this is truly desperate stuff here

bold coral Dec 11, 2023, 6:07 PM

#

J1233 is a OnePair here, no?

#

cuz that'd be (1,_),(1,_),(1,_),(2,false)?

hazy abyss Dec 11, 2023, 6:07 PM

#

this is sorted

#

J always ends up at the bottom of it's freq

#

for example

spiral zinc Dec 11, 2023, 6:09 PM

#

...this is one of the approaches to this problem of all time

bold coral Dec 11, 2023, 6:09 PM

then how would (2, true), (3, false) happen?

hazy abyss Dec 11, 2023, 6:10 PM

false false true false false

bold coral Dec 11, 2023, 6:11 PM

that matches to OnePair tho

#

even tho it's 3 of a kind

hazy abyss Dec 11, 2023, 6:11 PM

#

how

bold coral Dec 11, 2023, 6:11 PM

#

how what?

#

how does it match OnePair, or how is it 3 of a kind?

hazy abyss Dec 11, 2023, 6:12 PM

#

actually i can test it this way

#

ah

#

it was being matched to TwoPair

#

not ThreeOfAKind

bold coral Dec 11, 2023, 6:13 PM

#

you're only matchin XYZ JJ for 1 1 1 2, and then you fall back to OnePair assuming that none of the first three are J if the pair isn't

hazy abyss Dec 11, 2023, 6:14 PM

hazy abyss Dec 11, 2023, 6:15 PM

I literally cannot handle the logic of this

#

brute forcing all the routes is at least iterative somewhat

bold coral Dec 11, 2023, 6:17 PM

is it?

However when I do this i never get a result, I've rewritten it a couple of times now and keep getting the same thing over and over again >:(

oh no that approach ||will take way too much time it's not the intended way||

hazy abyss Dec 12, 2023, 1:37 PM

#

grrrrrr

#

computational limits can't stop meee

#

the other way is so much nerdness

spiral zinc Dec 12, 2023, 1:39 PM

#

embrace the nerdery

hazy abyss Dec 12, 2023, 1:40 PM

#

I guess I'll do the (what I believe is only slightly smarter) way of ||recording the entire loop for each path, and then just looping on that instead to find the one||

#

if that i too slow then it's just gonna be thinking about math which I don't want to do

stray violet Dec 12, 2023, 4:15 PM

#

I'm way too low for 12b noooooooo

#

there are so many cases I'm not hitting

#

which probably means my base cases are too strict?

stray violet Dec 12, 2023, 9:38 PM

#

bruh

#

hours later, my thing is finally valid, but it's still really slow on the main input

stray violet Dec 12, 2023, 11:41 PM

#

OH MY

#

the good news: my code is now super fast
the bad news: it's still wrong

hazy abyss Dec 12, 2023, 11:45 PM

#

literally me with day 8 part 2 lol

stray violet Dec 12, 2023, 11:48 PM

#

there has to be some edge case

#

I'm passing the small input

spiral zinc Dec 13, 2023, 2:02 AM

#

i didn't have time to do it today, i'll probably just have to come back to it over the weekend or smth like that

stray violet Dec 13, 2023, 4:38 AM

#

DONE

#

lfg lfg lfg

#

so it seems the small input's test cases were not comprehensive

#

only 20 minutes to rest until the next day

hazy abyss Dec 13, 2023, 2:51 PM

#

I am absolutely fucking done with day 8

oof

#

i have an overly complicated idea to mutlithread day 8 part 2

#

with likely a lot of pointer shenanigans

stray violet Dec 14, 2023, 4:26 AM

#

please be doable today 🙏

#

yesterday was pretty easy though, my confidence is not high

spiral zinc Dec 14, 2023, 8:45 AM

#

hmm how the hell do i do this without ||iterating a billion times||

stray violet Dec 14, 2023, 12:21 PM

#

||I found a cycle and used mods||

winter ether Dec 14, 2023, 4:50 PM

#

i definitely felt like that if today's part two didn't go well first try i would not have been smart enough to debug my own code

stray violet Dec 15, 2023, 5:20 AM

#

finally something I could do in 15 minutes

#

(reading aside)

winter ether Dec 15, 2023, 1:51 PM

#

oh my day 15 completely rewrote how i will read ||hash|| and ||hashmap|| from now on

stray violet Dec 16, 2023, 5:53 AM

#

I hate my solution but it's done
(theme of aoc)

spiral zinc Dec 16, 2023, 4:11 PM

#

lol that was me for day 14

spiral zinc Dec 16, 2023, 7:32 PM

#

i may have hit that point where i miss a couple days of aoc and the motivation really starts to dwindle

stray violet Dec 16, 2023, 7:33 PM

#

I'm currently on a long flight that lands just minutes before the next day drops, so I hope I don't miss it

I feel like I'm getting somewhere today but implementation is ehh

stray violet Dec 18, 2023, 6:45 PM

#

this was another one that took me the entire day

#

but we did it!

#

it involved 3 separate drawings and even building the problem in minecraft

quiet frigate Dec 18, 2023, 6:56 PM

That's adorable

stray violet Dec 18, 2023, 8:47 PM

ok now to catch up on 17, it looks like ||dijkstra's with a ton of extra steps||

bold coral Dec 18, 2023, 8:48 PM

oh no

stray violet Dec 18, 2023, 8:55 PM

oh it doesn't have to be contiguous

||input.map(|v| v.iter().filter(|other| other <= v).count()).max()||?

might be borrow checker problems

ah wait no

god part 2 looks terrible

we are MASSIVE

#

6 days to go, I can do this!!

winter ether Dec 19, 2023, 11:23 AM

#

somehow i managed to make a solution for day 17 that is single threaded non deterministic

#

i'm assuming it has something to do with how i'm abusing HashSet

#

idk how to even fix this

📎 SPOILER_main.rs

winter ether Dec 19, 2023, 12:53 PM

#

i changed every HashSet to a vector and it resolved the issue

winter ether Dec 19, 2023, 3:33 PM

#

don't do it like me I'll have to rethink the approach because i forgot about it for 2hrs and it still isn't done

gray bramble Dec 19, 2023, 11:53 PM

#

bold coral ||`input.group_by(|a,b|a<=b).map(|a|a.len()).max()`||

I think this is fairly close; my solution to this would be:
||```js
// assuming input: [0,1,1,2,2,1,3,5]
input.groupby(a=>a).map(a=>a.length).max()
// (elf's number) (arr len)

bold coral Dec 19, 2023, 11:55 PM

#

That just maps everything to how often it occurs, no?

#

Missing all the lower numbers

gray bramble Dec 20, 2023, 12:00 AM

#

For the example of 8 elves:
||[0,1,1,2,2,1,3,5] -> [[1,1,1],[2,2],[0],[3],[5]] -> [3,2,1,1,1] -> 3||, which is the example soln

#

gray bramble For the example of 8 elves: ||[0,1,1,2,2,1,3,5] -> [[1,1,1],[2,2],[0],[3],[5]] -...

That's just coincidence and wouldn't work if the input was reversed

stray violet Dec 20, 2023, 9:13 AM

#

part 2 usually does require some thought, but I think for the first time I genuinely have no idea where to start on today's part 2

#

it is not obvious to me at all how you would start this one

#

solution: leave a bad solution running and go outside!

stray violet Dec 20, 2023, 9:30 AM

#

I have something now, but I'm not sure it's accurate and even if it was coding it is going to be really difficult
