@UnrelatedString is it flexible

Unrelated String

it's... really not designed for such a use case

Redwolf Programs

I'm hoping I'll get top 100 again today, which might be enough to put me on the global leaderboard

Razetime

@UnrelatedString sad

Redwolf Programs

With my library, I'll either totally throw or get top 100 lol

There is no in between

Unrelated String

like the vast majority of builtins are just defined as lambdas in the dict that maps atom tokens directly to them

Razetime

03:56

is there a jelly function to take a program string and argument array, returning the output?

should be helpful enough with solving

Unrelated String

think so but doesn't help the issue of actually typing half the builtins quickly without the bookmarklet

guess the whole thing could be done in browser

Razetime

make an editor extension maybe

too much work honestly

Unrelated String

oh yeah

that is an option

Razetime

might as well just use numpy and whatnot

lyxal

@UnrelatedString laughs in on-screen keyboard built into online interpreter

Unrelated String

04:01

honestly since my current workflow requires me to copy paste the input in repeatedly doing a solution on tio is not a terrible idea

hyper-neutrino

laughs in on-screen keyboard AND keyboard shortcuts for every character in both jelly and vyxal built into online interpreter

except for the online interpreter part cuz i just leech off of TIO/vyxal PA

PyGamer0

i threw yesterday

Razetime

wonder if Doormat will get the #1 this year

@PyGamer0 this is your first AoC right

PyGamer0

yes

> 14) 340 tjjfvi
15) 339 hyper-neutrino

Razetime

don't think about speed

just focus on finishing the problems

PyGamer0

04:12

yeah i didnt finish day 3
part 2

Razetime

finish it now

Unrelated String

^

PyGamer0

i cant, not on my computer

can i finish it later?

Razetime

ah i see

yeah there's no real time limit

PyGamer0

@Razetime ok cool

hyper-neutrino

04:17

yeah you can go back and solve 2015 day 1 if you want

lol

PyGamer0

wat lol

hyper-neutrino

yeah the problems never close

PyGamer0

does first place on the leaderboard get a prize?

Unrelated String

if i really wanted to i could probably solve 2020 day 20 part 2 in a month hypothetically speaking

hyper-neutrino

don't think so

@UnrelatedString 💀

Razetime

04:19

@PyGamer0 there is no money in aoc

PyGamer0

ok

i think the first place gets atleast recognition

Razetime

usually the first place winners are also winning in other big contests as well

PyGamer0

which other big contests?

Razetime

codeforces stuff

PyGamer0

is the right side of the calendar ascii art?

Razetime

04:22

there's many competitive coding contests and stuff

@PyGamer0 yes, check the prev years

tjjfvi

04:40

20m

I think the brown is the path of the sub

And the blue at the top is the ocean surface, which fades away to the left due to the sub's increasing depth

Redwolf Programs

Oh, that's a good observation

Under 10m

tjjfvi

04:55

5m

Redwolf Programs

5m

hyper-neutrino

2m

today's music

1m

not many people here today or smth?

Unrelated String

just really preparing

hyper-neutrino

30s

fair enough

Redwolf Programs

I was busy reading about the draft, the NMSQT, and chemical weapons

hyper-neutrino

04:59

lol

20s

The Fifth Marshal

15s

hyper-neutrino

10s, GLHF everyone

PyGamer0

i just finished day 3 part 2

and day 4 started lol

the puzzle input looks like APL matrices

lyxal

what the actual hell is this puzzle format?

hyper-neutrino

6/21

it took me an absurdly long time to figure out what exactly part 2 was trying to get me to do lol

Redwolf Programs

05:11

Yes!

106/96

First time I've ever top-100'd on a part 2

Razetime

i'm gonna be super late today

hyper-neutrino

@RedwolfPrograms congrats!

Redwolf Programs

I got a wrong answer for both lol

This was tough for day 4

Under 200 completed still lol (for part one!)

Unrelated String

i really don't know how to actually debug this stuff

lyxal

@RedwolfPrograms because of input formatting probably

Unrelated String

05:12

niiiice

Redwolf Programs

Debugging it sucked

My mistake was multiplying by the wrong number

Unrelated String

oh yeah i forgot my method of handling blank lines fucking SUCKS

i just had to add more to the end

and it worked

Redwolf Programs

Input parsing was the easiest part for me

Is it harder in other langs or something?

Just split, slice, and filter

lyxal

@RedwolfPrograms it is in golfing langs

Redwolf Programs

If I didn't make those two mistakes, I'd probably have been top 20 or 30 or so for both parts

I used some horrible, horrible mix of maps, for loops, some/every, and setting undeclared variables in the conditions of if statements

hyper-neutrino

05:16

i lost valuable seconds because i did .split("\n\n")

and got trolled cuz my editor

saves with \r\n

tjjfvi

I missed "Diagonals don't count"

Redwolf Programs

Using JS is nice since you can just use the console

hyper-neutrino

@tjjfvi oh, that's incredibly unfortunate

Redwolf Programs

No copying/pasting, predictable I/O

tjjfvi

Spent a while debugging why my thing was detecting an early win

hyper-neutrino

05:17

ooh, 11th

so i'm already at where i finished last year lol

Redwolf Programs

Oh nice!

hyper-neutrino

oh nice doorknob is top global rn

i said my goal was top 10 for this year but if i'm already here i might set my goal to 5 instead

Unrelated String

lmao

Redwolf Programs

I was confused for a second because you're tied with someone with a last name off by a letter and I was 99% sure you weren't a Robert

Razetime

@RedwolfPrograms in BQN yes

Unrelated String

05:19

finally got a rank that it pbothered to tell me on both stars

412/505

Redwolf Programs

Nice!

Unrelated String

thanks

The Fifth Marshal

613/525

Unrelated String

nice

The Fifth Marshal

First 3-digit rank on a part 1 for me

Unrelated String

05:20

oh yeah wait this is my first three digit since 1-1

Redwolf Programs

I notice we're all climbing a lot, that's cool

The Fifth Marshal

Except for the first day (when I forgot advent of code was a thing until 7PM), I've always gotten a 3-digit rank on part 2

hyper-neutrino

i'm rather annoyed with my poor reading comprehension

i had to fix my second part solution like 4 times

and my final correct version was actually simpler than all of the wrong versions i implemented

Unrelated String

i understood part 2 as i read it but i didn't understand it as i implemented it lmao

Redwolf Programs

I was #6 in the PPCG leaderboard for a few minutes until a few people caught up with me (I'm #8 now)

Unrelated String

05:23

choked a bit on how to filter boards out then neglected to actually let the final board complete properly

Redwolf Programs

Same!

I was halfway through typing that out lol

I think that was a common mistake

Given that I made it and still managed to move up in rank from p1 to p2

hyper-neutrino

@UnrelatedString same :/

Unrelated String

my row and column bingo checks were completely separate so i didn't want to copy paste the same thing in twice but this is fucking aoc of course i should copy paste the same thing in twice

hyper-neutrino

first time i ended the loop when the remaining boards was length 1

then i got stuck on whether the multiplier was meant to be the callout that made the last board win or that made the first board win

The Fifth Marshal

I made exactly the same mistake in my code

hyper-neutrino

05:25

(because i was actually outputting the callout that made the second last board win)

Unrelated String

oh

oh wait no yeah i was doing that too

hyper-neutrino

glad to see we all have the same reading comprehension issues 💀

Unrelated String

difference being i uynderstood from the start that i had to use the score for the actual final board but completely negleclted to implement it that way lmao

Redwolf Programs

^

hyper-neutrino

nice

i thought it was callout for final board

but since i was outputting second last board by accident i thought i interpreted it wrong

and swapped it to first board

Redwolf Programs

05:27

I feel an odd sense of comraderie in our collective failure to do that part right :p

hyper-neutrino

lol

Unrelated String

lol

hyper-neutrino

~~ape together strong~~

Redwolf Programs

My goal this year is to try to make it onto the global leaderboard

I'm not too sure I'll be able to, but I've definitely got a more solid start than last year

Unrelated String

you got this

hyper-neutrino

05:31

i believe 🙏

Redwolf Programs

Thanks! :D

lyxal

05:42

wow holy crap part 2 is way easier than part 1

hyper-neutrino

are you high

lyxal

nope

hyper-neutrino

how is p2 easier

am i like

lyxal

my part 1 is accidentally optimised for part 2

hyper-neutrino

damaged in the brain

Unrelated String

05:43

lo

l

lyxal

I'm already getting whether or not each board wins

from there, it's just checking a) if all boards have a win and if so b) which board changed?

Unrelated String

honestly my part 2 was a modification of my part 1 that would have been trivial if i didn't suck

hyper-neutrino

my p2 took a bit more messing around with to get it to work

Redwolf Programs

Y'all writing whole programs and not just typing 50 different one liners in the console and gluing them together by hand

hyper-neutrino

but it still would've been pretty easy if i weren't stupid

lyxal

05:48

yep as I said, trivial modifications for p2

by over-engineering p1, p2 was ez

hyper-neutrino

oh you mean like

the transition from p1 to p2

was easier than writing p1 itself

lyxal

yep

hyper-neutrino

i thought you meant you thought p2 as a whole was easier than p1 and i was like

no?

Unrelated String

lmao

lyxal

p2 only needed 26 extra bytes

hyper-neutrino

05:50

oh right you're using vyxal

i was like that is a really small amount of modification wtf

unless you weren't using vyxal and it was actually just that close

lyxal

I was

part 1 v part 2

hyper-neutrino

nice

lyxal

if aaron or emanresuA were here, they'd say that they hate what I wrote

←boards `

`/`  ` ` `vV↵

ƛ⌈ƛ';;⌊;

that's what input parsing looks like when pain

wait I'm actually in the top 1000 for part 2?

holy frick

Unrelated String

ayy

lyxal

that's my first 3 digit in part 2 this year

502nd

hyper-neutrino

05:55

nice!

Redwolf Programs

Nice!

Dang, still three digits for p2? Must be a seriously hard one

Loool look at the stats graph

lyxal

well dang

Redwolf Programs

It's too early in the month for a Great Filter

Unrelated String

lmao

lyxal

looks like I'll be able to only do 1 star tomorrow and never be able to do AoC again

because rn I have 68 stars total from 4 years

Unrelated String

05:57

interesting to see what those stats look like in 20 hours or so because there's no way this was that hard for that many people

😔

wait have you done aoc for four years or is some of that doing past year problems for practice and fun

lyxal

so this is what they mean by squid game

@UnrelatedString 4 years, never completed all 25 days

Unrelated String

nice

lyxal

Unrelated String

if we deny the existence of sea monsters i completed 25 last year but not the year before

hyper-neutrino

i've full solved 2015 and 2020

2020 because i was competing, 2015 because i upsolved while developing my library last year

Unrelated String

05:59

oh yeah maybe i should go back and finish my gaps from 2019 once i'm done with finals

hyper-neutrino

which i cannot find anymore and don't want either kekw

Unrelated String

lmao

hyper-neutrino

once this term is done i will work on a better command line utility for this

idk why i tried doing lisp-like the first time i tried making a pseudo-language for it

stack based is clearly both easier to implement and use lmao

Redwolf Programs

Well, I'm going to sleep now, gotta get up early the morning after tomorrow o/

hyper-neutrino

o/

lyxal

06:01

to whoever implemented the global array in vyxal: thanks for wasting a bit of my time today

hyper-neutrino

lol

lyxal

because I tried to use it but it silently errored

hyper-neutrino

rip

lyxal

and for a very stupid reason

Unrelated String

the big thing i've been thinking about is just having a robust way to toss some shit together to parse the inputs nicely

lyxal

06:01

anyone wanna tell me what's wrong with that?

(btw, ctx.global_array is a default python list)

hyper-neutrino

wait

isn't it append

Unrelated String

oh

lyxal

@hyper-neutrino correct!

hyper-neutrino

push is a JS thing no?

kekw!

Unrelated String

wait why would the error be silent doesn't python list literally not define push

hyper-neutrino

06:03

prob bad error handling by vyxal

lyxal

^

Unrelated String

nice

lyxal

you know AOC is fun when you have to use the offline vyxal interpreter on the command line

hyper-neutrino

bruh moment

Razetime

wait

giant squid?

is aoc gonna have squid game and a submarine as their ascii art

hyper-neutrino

06:15

oh no

Unrelated String

06:36

:|

in other news wow the completion still hasn't reached 10k

Razetime

06:48

finally finished it

somehow my rank isn't 5 digit

my part 2 was quite awful

@UnrelatedString about 3k more to go

considering my rank was in the 7000s for both of em

Unrelated String

lol

adventofcode.com/2021/stats

Razetime

i'm half sure both parts have a nice array oriented solution

i finished part 1 and realized my part 1 didn't check the antidigagonal at all

lyxal

You don't need to

Diagonals don't count

Only rows and columns

Razetime

oh well

PyGamer0

i am not sure where to start

so i am not doing it lol

Razetime

06:56

@lyxal then i am lucky my solutions were right at all

Unrelated String

i wonder if the input was actually engineered not to punish you for checking diagonals or if you did get really damn lucky

lyxal

@PyGamer0 start by writing a function that removes called numbers from a board

Make sure to maintain the shape of the board

Then write a function that checks if all items in a row or column are empty

Unrelated String

i.e. just zero them

Razetime

@UnrelatedString it does specifically say diagonals don't count

lyxal

@UnrelatedString not exactly

Razetime

06:58

@UnrelatedString do NOT zero them

-1 them

lyxal

^

hyper-neutrino

wot

Razetime

0 is a valid bingo number

Unrelated String

all i know is i zeroed them and it worked

hyper-neutrino

bruh?

Unrelated String

06:58

???

hyper-neutrino

same

Razetime

lmaoooooo

Unrelated String

what

lyxal

Y'all got lucky

Razetime

0 was one of the numbers in my input

Unrelated String

06:58

WAIT IT IS

hyper-neutrino

💀

Unrelated String

it's literally in the example input

Razetime

gmaing

hyper-neutrino

the example literally has it

lyxal

Lol

hyper-neutrino

06:59

and it didn't even fail the example

Unrelated String

lmao

yep

Razetime

advent of code that technically works

hyper-neutrino

07:21

reddit.com/r/adventofcode/comments/r8jdvt/…

lol, yeah

Razetime

reddit.com/r/adventofcode/comments/r8ixmk/…

hyper-neutrino

07:35

ngl "do diagonals count" was one of the first things i checked when i saw "bingo"

or rather, remembered to keep an eye out for

Razetime

i am very very lucky

emanresu A

Gerat, I forgot about tday's as well

hyper-neutrino

F

Razetime

i forgot how fast neutrino was, top 11 last year

cgcc leaderboard has so many pros

emanresu A

Great, input parsing

hyper-neutrino

07:48

all my competitive programming experience def helped

Razetime

hm how do we get Legionmammal978 on the private leaderboard

they're also on the global ranking

hyper-neutrino

i haven't been doing cp since grade 7 for nothing

Razetime

@hyper-neutrino i recently tried and honestly idk if i'll get good at it

emanresu A

Btw NaN is my favorite number

hyper-neutrino

i was never really good at it, lol :/

emanresu A

07:51

Oh wait

hyper-neutrino

somehow, i got into my country's national competition and completely failed that

emanresu A

It's cos I split on spaces and they padded mininumbers

hyper-neutrino

lol

emanresu A

ಠ_ಠ When using an integer parsing function fails and casting to a integer works

Razetime

@hyper-neutrino which country is this

PyGamer0

07:55

canada?

hyper-neutrino

^

Razetime

north america in general is hypercompetitive for programming

emanresu A

That moment when you're playing 4D bingo

Unrelated String

i feel like it can't be that general a north america thing if there's so little around here

Razetime

another CGCC user we should get on the leaderboard is Oliver Ni

hyper-neutrino

08:01

i mean granted

i attend and live right next to one of the more well-known unis for STEM in canada lol

Unrelated String

lol

hyper-neutrino

(it's actually the one that runs all the nation-wide math and CS contests that people actually care about)

emanresu A

CMC: Given a bit matrix, check if at least one row or column has all items truthy

Unrelated String

oh nice

emanresu A

(I have 48 in JS)

hyper-neutrino

08:02

(which is great cuz some people fly in from across the country and i'm just like)

(man i could've walked here)

Razetime

what if they ask you to move out of town and fly in for the contest if you qualify

PyGamer0

@emanresuA i see what you have done

emanresu A

4 mins ago, by emanresu A

(I have 48 in JS)

I've done it

It's just a fun CMC

PyGamer0

@emanresuA then post it in tnb

hyper-neutrino

@Razetime oh i mean i'd do it

i mean i ended a family vacation and flew back alone on my birthday to attend a thing at the uni (was in HS at the time)

Razetime

08:13

@emanresuA ∨´·∧´˘⊢∾⍉

hyper-neutrino

wait

i just got what you mean

wtf

Razetime

@hyper-neutrino lmao

i was confuse for a bit when you agreed lmao

hyper-neutrino

yeah i thought you just meant like what if i had to fly out of my city to attend

but no your message is incredibly cursed

emanresu A

Apparently the solution to part one is either 25 or 0.

PyGamer0

@Razetime is that bqn

emanresu A

09:52

Part 1 complete!

(It only took me two hours)

(Because JS objects are very weird sometimes)

Razetime

@PyGamer0 yes

@emanresuA happens

emanresu A

I thought #2 would be a trivial modification

But it isn't, idk why

lyxal

It is depending on how you wrote part 1

Part 2 only required an additional 26 bytes for me, and that included adding a 4 char long variable

emanresu A

10:08

As in I made a trivial modification (actually similar to the amount you changed) but it didn't work

emanresu A

10:18

Great, I just lost all my code.

lyxal
