spotify sponsors AoC?

Redwolf Programs

Lots of big companies do

lyxal

I wasn't expecting spotify though

Redwolf Programs

Capital One and American Express are two I wouldn't expect

lyxal

wait no way

holy crap they do

Redwolf Programs

AT&T sort of does

Through a company they own

lyxal

04:28

Redwolf Programs

Riot Games does

lyxal

@lyxal why do I feel like that'd be a turn off for some people?

Redwolf Programs

"Better pass those unit tests or you'll kill ten people"

I love how the word for "raincoat" in spanish is "impermeable"

Unrelated String

04:32

makes sense tbh

lyxal

serious question: how many people have actually bothered to read this years lore from day 1?

I haven't

Redwolf Programs

Same

I know we're in some caves

But that's about it lol

lyxal

I know we're getting keys and that we're in a submarine, but that's it

Redwolf Programs

Submarines are overrated, tree domes are where it's at

Although I may be biased because I'm a land mammal from texas

lyxal

@RedwolfPrograms for a moment then I read biased as based

Redwolf Programs

04:37

That too

PyGamer0

@lyxal yes the tacit system is based

no doubt about it

dah frick I suck at oregano

Redwolf Programs

Did all te folds fanf

lyxal

bruh with the amount of sense in that message, it sounds like you need to go back to sleep school and learn how to rest

not bad

127pts behind ecner, up 7pts from yesterday

Redwolf Programs

Wgat tge fricj does it mean 8 capital letters?!?!?!?!

Unrelated String

i love when the sample works but my real input doesn't

i just got the sample wrong and the real one right

emanresu A

I've got an off-by-one error somewhere

tjjfvi

My part 1 solution was broken but it still gave the correct result lol

Redwolf Programs

Close to being back on the leaderboard

Totally screwed up p2 lol

I accidentally used the un-folded output instead of the folded output

Then, after fixing that, I accidentally outputted it transposed

But I didn't know what series of flips/rotations I'd accidentally applied

hyper-neutrino

05:12

@tjjfvi lol

Redwolf Programs

And for p1, I accidentally did all the folds, but somehow still placed in top 100

Despite the 60s wait

I could've got top 10 lol

tjjfvi

Wow

Unrelated String

so i tried graphing the p2 result and i do not see any letters

uh

Redwolf Programs

Today I do not feel like a failure!

@UnrelatedString Same, did you do all the flips?

Unrelated String

yep

emanresu A

05:13

Mine's cursed

hyper-neutrino

my p1 was relatively slow because i didn't get my input processing method set in my mind fast enough so i started writing code and then had to quickly revise it twice which cost me a bunch

Unrelated String

lol

hyper-neutrino

at least i remembered that my editor saves with \r\n

Redwolf Programs

I applied all the flips, but then forgot to use that variable instead of the one with just one flip lol

hyper-neutrino

so i didn't get fucked by that :p

Unrelated String

05:14

okay so i'm getting a graphically wrong but numerically right result on the sample

hmm

Redwolf Programs

I told myself over and over again to make sure to read better today, and then lost a possible top 10 because I didn't read :p

Unrelated String

rip

wait what the fuck am i literally just missing the last fold

how

Redwolf Programs

Rip :/

emanresu A

I've got an off-by-one error?

Unrelated String

wait no it's more than that

emanresu A

05:16

And I don't have an actual grid :p

Unrelated String

i knew my fold logic was too shit to work

The Fifth Marshal

Folding isn't actually that complicated

hyper-neutrino

yeah

Redwolf Programs

Mine used something along the lines of flip_coord - abs(flip_coord - original)

hyper-neutrino

the way i did it was actually kinda bad

i should've used abs instead of ternary

Unrelated String

05:17

lol

hyper-neutrino

anyway with jelly you could just like

slice the array

reverse one side

and overlay with |

or sorry, with any array language

Unrelated String

lol

Redwolf Programs

Flipping and discarding one of the rows kinda threw me off

That will definitely give some people off-by-one errors

emanresu A

But in p1

Unrelated String

ahhhhhhhh

i was handling the axes wrong

Redwolf Programs

05:21

@emanresuA This is for p1. When you flip, are you using a row/column itself as the axis, or an imaginary line between them?

Unrelated String

finally got it by changing 1j**(f[0]=='y') to (-1j)**(f[0]=='y')

emanresu A

My broken code

@RedwolfPrograms ಠ_ಠ That could be the proble

Except I've tried correcting those errors...

Unrelated String

327/983 lmao

Redwolf Programs

(You should be using the row/column itself, if you're not doing that)

emanresu A

(Inserting +1 and -1 in coordinate changes)

(But it's not doing that

Redwolf Programs

05:23

Your folding logic is the same as mine it seems

Are you doing all the folds in p1?

emanresu A

Just one

(Two makes no difference either)

Redwolf Programs

Does .map(Number) after the .split`,` in your input parsing change anything?

I don't think it's a typing issue but idk

emanresu A

Oh

Just realised that, will see

Redwolf Programs

It looks like all you do is subtracting, so it shouldn't matter, but idk

emanresu A

OH.

map doesn't modify the original

Redwolf Programs

05:28

Ohhh

I didn't notice that, I was busy trying to debug the last few lines

Unrelated String

the one thing i wish had been different tonight is that the sample should have been larger so the dumb shit i did for part 1 would have been fresh in my mind when i had to fix it because i wouldn't have been able to get the right answer by complete accident

lyxal

so the fun thing is that my solution works for the sample, and probably works for the actual input, but takes a very long time to do things

hyper-neutrino

F

emanresu A

Victory!

Redwolf Programs

Nice!!!

Very pogchamp

lyxal

05:34

that's my p1

emanresu A

ಠ_ಠ Don't make a grid if you can avoid it

And in this case you can

lyxal

too bad I'm like 1 minute into running my program

I will listen to the entire undertale ost if i have to I'm doing the grid method

besides idk how to do it gridless

emanresu A

For each point, fold it over the line

lyxal

mm yes very helpful

seriously tho tf do you mean?

emanresu A

For each point:
- If the fold's axis is x, set the x coordinate to (foldpos - abs(foldpos-x))

- Otherwise do the same but for y

Razetime

05:48

ok wait

i have the final matrix for p2

what the hell is this final answer aaaa

Redwolf Programs

You have to visualize it in some way and read it as text

Fun

Razetime

ok what a cute answer nvm

Unrelated String

ikr

@emanresuA in this case you literally have to make a grid for part 2 but you don't need it for intermediate steps and the points are very sparse to begin with so yeah

lyxal

I shall use the power of desmos for part 2

3

I'm uh assuming the dots aren't supposed to have negative co-ords...

Bubbler

06:06

Surely it reads "lyxal bad"

emanresu A

That is eight letters

lyxal

@emanresuA for some reason that produces negative coords

emanresu A

Shouldn't

It's what I used

hyper-neutrino

send code

oh wait it's vyxal i can't read it anyway oops

lyxal

i was about to say what help would that be

hyper-neutrino

06:11

i normalized the points to eliminate negatives which uh

lyxal

``€÷$ →dots →folds

←folds hw (fold|
   ←fold `[xy]=\d+` $Ẏ\=/f÷$ →axis ⌊→_pos
   ←axis `x` = [
     ←dots ƛ←_pos nh ←_pos -ȧ- nt"; →dots
   |
     ←dots ƛnh ←_pos : nt -ȧ-"; →dots
   ]
 )

 ←dots Uƛ`(%, %)`$%;⁋

hyper-neutrino

apparently is not necessary, it's already aligned

lyxal

and it produces points like:

(-887, -100)
(-465, -237)
(-450, -48)
(-37, -287)
(-1085, -807)
(-878, -62)
(-465, -219)
(-1230, -452)
(-45, -629)
(-821, -459)
(-1280, -772)
(-1220, -705)
(-886, -215)
(-430, -737)
(-881, -104)
(-383, -411)
(-1292, -683)
(-199, -174)

hyper-neutrino

does it work on sample

lyxal

no

but it worked for part 1

hyper-neutrino

06:14

hm

Razetime

oh, you're making a bunch of negative points so you need to normalize everything to 0, 0

by adding the max x and y to everything

lyxal

nope it was a global variable/lazy evaluation issue

Razetime

oh lmao

lyxal

the prospect of an "immediantly apply" lambda is looking more and more yes

got it

two d13 stars

Razetime

neato

Redwolf Programs

06:20

Nice!

emanresu A

^

lyxal

I do love being screwed over by the lazy evaluation i worked so hard to bug fix purely because global variables and because python's exec is hella janky sometimes

Redwolf Programs

Idk why I added the "people with bunny ears" emoji but it popped up when I searched "party hat" so why not

Razetime

I ignored the unrelated string advice today and just used 2D arrays

totallyhuman

06:45

i continue to have an off by one error that i cannot find

despite already having gotten both stars

because of an almost readable output that i got

so dumb
