Q: CGAC2022 Day 4: Can Santa fit down the chimney?

Part of Code Golf Advent Calendar 2022 event. See the linked meta post for details. Christmas is coming up, and Santa hasn't kept to his diet very well this year. Due to his size, he is getting the elves to collect a list of all the chimneys he will be able to fit down. Unfortunately, chimneys t...

A: Sandbox for Proposed Challenges

Write a program that prints a program that's almost quine. code-golfquine Your task is to make a program in L that takes n as an input number, output a program p in L that prints the first n characters. Rules You can't make a program that outputs a program p, if you removed a substring of p and ...

@mousetail What are the specs?

O_O

-_-

:((((

is that :( because you're so close or because you once passed the milestone and got downvoted?

nah i didnt pass the milestone yet

would you like to?

hmmmmmmmmmmmmmmmmmmmmm

very tempting

1:03 AM

haha just kidding you don't get a choice

welcome to the club

LOL LETS GOOO

10k club yessssss

ok now i gotta see some juicy deleted posts

u got any off the top of ur head

one second

I actually have 2 such posts

gotta find the links

Radvylf Programs

You gotta avocad

codegolf.stackexchange.com/questions/60206/…

found it in my post saves :p

also codegolf.meta.stackexchange.com/q/5828/78850

The adovocad makes a polite request. Do we choose to achnowledge it?

I thik so

wtf this is strange, on meta im still at 9999 rep

What do y'all think about codegolf.meta.stackexchange.com/a/25367/79857

I intuitively feel like the first rule makes the challenge either trivial or difficult and very interesting and I can't figure out which

Since it's basically asking you to make an infinite slice of a program which can have some boilerplate tacked on the end to print how long that slice is

I think the irreducibility requirement is basically a dead letter

Anyone using the new C23 features?

where?

has it been released?

Coming in gcc 13

I mean it exists in gcc 13 already I think

oh

gcc.gnu.org/gcc-13/changes.html

I didn’t know auto had been in gcc since version 11

I guess clang will have c23 support too

that's

@UnrelatedString I still have a bit of bill wurtz energy from interacting with gpt chat :p

lmao

For example: gist.github.com/Lyxal/8c0b5b8d90862b51e0c8fd37142e3531

You've probably seen it but it's where the corn idea came from

9:20 AM

lmao

9:38 AM

@lyxal Maybe should've waited until it was dealt with

Unrelated String

oh i did not realize that it's an actual (low quality) programming question

all i saw was turkish and a link so i just flagged as spam lmao

@UnrelatedString but the link goes to some law consultancy website, pretty sure it’s spam

Unrelated String

the question seems to be for help making the law consultancy website :P

~~they can spam it later once the menus have subtitles~~

9:55 AM

@UnrelatedString ~~in stack overflow~~

Wtf is my phone doing lmfao

Unrelated String

i know iphones try to smart emdash

not really sure how to avoid it beyond insrting then deleting extra stuff in between

@UnrelatedString ok that worked, pretty annoying tho

Unrelated String

yeah

real pain in the ass

Wish I could turn that off

@emanresuA even still, it's low quality and would have been moved whether spam or just vlq

A: Sandbox for Proposed Challenges

Merging strings Not sure if this is already done Basically, take two strings of reasonable length (like <32 chars) of numbers and X's and find the shortest superposition of those strings such that there's no 2 numbers at the same position. Number+X or X+X is allowed. Print the result.

Q: Output the length of (the length plus a message)

The task is simple. You're given an arbitrary string message. Return that message prefixed with a number, such that the length of that number plus the message equals the number. In other words, the length in your output must be the total length of your output. If multiple candidates exist, you ca...

Hello!

yeah sex is great but have you ever replaced 30 lines of awful kludges with 3 lines of streamlined perfection

Unrelated String

i have done neither 😎

Same

10:43 PM

skill issue

@Ginger I've replaced 30 lines of streamlined perfection with 3 lines of awful kludges :P

~~although for it to be a fair comparison I'd have to have an idea of what both things are like, not just one~~

11:08 PM

It'd also depend greatly based on the circumstances

For example, turning 30 lines of awful Java kludges into 3 lines of streamlined perfection won't feel like a huge difference because 30 and 3 are basically the same in the Java world and you'll still have 30k lines of awful kludges left

Unrelated String

it really just means you hid 100 lines of awful kludges somewhere else

Or that someone else's library did it for you

Unrelated String

I think at least a couple of really nice Java libraries I used had an ungodly amount of reflection inside

Unrelated String

no surprise there :P

reflection seems like a godawful idea for what java seems like it should be
but considering java is actually java, it borders on necessary

11:14 PM

You kinda need reflection in a statically typed language with a type system that restrictive

If Java had better compile-time reflection we wouldn't need as much runtime reflection

Unrelated String

yep lmao

But it doesn't even have a proper unified interface for annotation processors that want to do modify code. I think stuff like Lombok has to detect which compiler's being used and use specific approaches based on that

Unrelated String

holy shit

Although apparently there's only like two compilers that everyone uses (source (SO answer by one of the devs))

CMC: given a positive integer, return a string of that many characters with a charcode sum that is divisible by that number

So for n = 5, you'd want to return a string where sum(map(ord, s)) % 5 == 0

Unrelated String

11:28 PM

am i missing something or would any string of that many of all the same character work

Hm

Not for n = 1

Nonwait

It would

Unrelated String

wh

yeah

lmao

CM-addendum: characters must be unique. If no such string exists, don't worry about it

Unrelated String

there we go

what do most golfing languages do when you pass an array and a list to the indexing operator?

Unrelated String

11:34 PM

probably vectorize

i.e. pray that the one that's expected to be an index is full of numbers, and return a list of items at those indices

so there's usually a separate operator for multidimensional indexing?

Unrelated String

at least in jelly there is

and i feel like vectorized indexing is more generally useful, but that's also within jelly's very array oriented model

(and even multidimensional indexing vectorizes, if you have a list of lists)

APL has multiple indexing operators, I think (at least) one of them vectorizes and one does multidimensional indexing. You might want to ask in the APL Orchard

Unrelated String

^

@UnrelatedString yeah, I was thinking of making Charcoal's indexing multidimensional, but with the option of a list of lists for vectorised indexing

so if you index by [0, [0, 1]] then you get the first two elements of the first row

11:44 PM

@lyxal Works for all numbers up to 1114111: if n is odd, use 0..n-1; if n is even, use 0..(n/2-1) + (n/2+1)..n

the answer does not exist if n >= 1114112
