The Nineteenth Byte

7:00 PM

on a scale of 10 to yes, how bored were you

Redwolf Programs

Here's the full thing if anyone wants to give it a read :p

user

What subject is this, anyway?

Redwolf Programs

Biology

user

Biology's fun

We had chickens in our class once, they were pretty cute

caird coinheringaahing

7:14 PM

@hyper-neutrino Just a question, why did you reopen this (and remove the comments) when the principle questions in the comments (are duplicate pairs allowed, is it safe "paths" or "places") were either not addressed at all, or "addressed" by adding in a test case and nothing else?

user

CMP: What is/was your least favorite subject at school?

Redwolf Programs

Least favorite this year is 100% english, although I'm usually fine with it

Wezl

same

user

@rak1507 Are duplicates allowed or not, then?

rak1507

@user yes, but it is a bit of a red herring, they don't make any difference

user

7:15 PM

I'm taking AP Lang and it's way too hard :\

@rak1507 Oh ok

rak1507

@user english last year, economics this year

user

Imagine taking big brain subjects like economics

@user French this year because I'm rusty and don't understand anything, probably PE and Health before that

My favorite subject was probably Software App Design, which had nothing to do with designing software applications

Unrelated String

classic

Redwolf Programs

Our PE is great because they don't care and we can't really do most things because of covid so we just walk in circles for half an hour then I code golf the rest of the time

user

Lol virtual PE

Redwolf Programs

7:19 PM

We had that for a while lol

user

I actually liked PE last year, before COVID, because it wasn't general PE, just tennis, table tennis, volleyball, and no standardized tests

Wezl

TBH in virtual PE it was harder than last year because there were less people, and there was one good teacher instead of a few who payed zero attention

user

The pacer and plank tests were the worst

@Wezl But they couldn't make you run laps or anything if you were at home, right?

Wezl

@user yeah so it still wasn't hard, it was just not super easy

hyper-neutrino

7:35 PM

@cairdcoinheringaahing from my reading of the explanation, it made enough sense to me. granted, i may be inserting my own understanding into text that others might not get, but i found it to be clear enough

i can edit in more clarifications since the question doesn't say duplicates aren't allowed but i guess it would be nice to mention that they explicitly are

> Given an array of logbook entries, your task is to write a function to return the length of the longest consecutive traversal possible; in other words, compute the maximum number of consecutive edges known to be safe. (In even more formal terms, compute the diameter of the largest tree on this graph.)

(emphasis my newest edit)

i found this to be clear enough that it meant consecutive paths, but i've added an edit that hopefully makes it more rigorous in case it's still unclear after reading what was already there

caird coinheringaahing

Hmm, I still think it's unclear on the safe paths/points part (and framing it as a logbook and trucking hasn't helped it tbh), but I suppose others may understand it clearly enough

hyper-neutrino

I personally think the flavortext is a bit too much, but that's subjective

also thanks for the edit on 'distinct'; i must've missed that since i noticed the explanation didn't mention that

caird coinheringaahing

Ugh, the newest question is a repost of a previously deleted post (by the same user), but NMP never posted it and self-deletes don't show up in the mod tools so I can't find a link to it :/

Wezl

@cairdcoinheringaahing codegolf.stackexchange.com/questions/223577/… ?

caird coinheringaahing

@hyper-neutrino What's kinda annoying is that I edited in the "distinct" part as part of my edit to clean it up, and the OP has basically just reverted it to how it was before I edited it :/

@Wezl Thanks!

hyper-neutrino

7:43 PM

I don't think it being distinct adds anything to the challenge but complicating the processing, but if OP wants it that way, then so be it

caird coinheringaahing

@hyper-neutrino Yeah, I added it so that answers wouldn't have to worry about it, regardless of any impact it might have

I have n strings of equal length, I want to minimize sum of number of different letters in each column

by permuting strings

what's this even called

StackMeter

a Latin Square

and it's been done before

FrownyFrog

yeah but unlatin

duplicates in rows may appear and I want them all in the same column ideally

caird coinheringaahing

@StackMeter I don;t think it has: codegolf.stackexchange.com/search?q=%22latin+square%22+is%3Aq

We've had some very closely related challenges, but I don't think we've had "Given a list of strings, rearrange it into a latin square"

FrownyFrog

I found "assignment problem" but this is multiway, and "consensus string" but it's not that

StackMeter

8:17 PM

I guess so

hyper-neutrino

8:31 PM

@cairdcoinheringaahing how do you have 12 bytes? is my solution missing something, because I'm pretty sure it's valid and I can just do it w/ 3b?

caird coinheringaahing

@hyper-neutrino I may have taken a permutations approach by not seeing the rotation version :/

hyper-neutrino

ah. rip :/

caird coinheringaahing

Well, let the FGITWing commence :P

hyper-neutrino

~~time to port my own answer to 18 different languages~~

caird coinheringaahing

explanation please ~~so I can answer in a language I know~~

caird coinheringaahing

for i in [1, 2, ..., x]: print(rotate([1, 2, ..., x], i))

hyper-neutrino

alright now that i've posted in a golfing language and my main production language, time to mess around with meme languages

caird coinheringaahing

I should've realised why there wasn't already such a challenge posted :P

Redwolf Programs

I've been missing out on FGITWs because I'm working on Ash and 10IPL :/

hyper-neutrino

i'm actually surprised there isn't

caird coinheringaahing

8:39 PM

+2 with 6 answers, ouch to that ratio :/

hyper-neutrino

imagine having a userscript to report new posts and still being beaten by someone who doesn't. this post made by the I Have No Life And Monitor CGCC Every 3 Seconds gang

Redwolf Programs

I forgot to open New Posts today anyway :p

hyper-neutrino

F

caird coinheringaahing

@hyper-neutrino Took a look at posts containing "latin square" or "rotate" and it doesn't appear to be, which is wild

hyper-neutrino

Yeah. I even tried looking for my exact Jelly solution in case the wording was weird but can't seem to find anything

Makonede

8:46 PM

hey, does anybody know how exactly TIO encodes the URLs? i'm too lazy to look through the source code

user

@cairdcoinheringaahing For your Latin Square challenge, is it okay if we take input as a stack composed of n empty stacks?

caird coinheringaahing

Did you use the search for it? Cause that won't work properly with the unicode symbols. I've got a Jelly analyser here with every Jelly answer, and it's also returned blank

Redwolf Programs

@Makonede Do you need to know how TIO specifically does it, or just a way to do something similar?

hyper-neutrino

@cairdcoinheringaahing well, searching for it gave my answer as a result lol.

caird coinheringaahing

@user If you're going to properly use Stack Exchange, you might want to establish some default I/O methods for it

Redwolf Programs

8:48 PM

(Am designing an online interpreter and working on that part of it right now)

user

Relevant: codegolf.stackexchange.com/questions/133399/…

Makonede

@RedwolfPrograms specifically how TIO does it

New Main Posts

Q: Output a Latin Square

An \$n\times n\$ Latin Square is a grid containing exactly \$n\$ distinct values where the values in each row and column are distinct. For example, $$\begin{matrix} A & B & C \\ C & A & B \\ B & C & A \\ \end{matrix}$$ is a Latin square as no row or column contains a repeated value. You are to ta...

caird coinheringaahing

@hyper-neutrino Yeah, but SE search is crappy with unicode symbols so it wouldn't find any others I think

hyper-neutrino

oh. you love to see it :/ well if you've verified with your analyzer then cool

user

8:49 PM

@cairdcoinheringaahing That's the IO method I'm going with (inputs are pushed onto the stack at the beginning of the program, numbers are stacks containing n empty stacks, strings are stacks of numbers/characters representing Unicode codepoints)

caird coinheringaahing

@user Yeah, but I mean as answers to the default I/O methods thread

user

@Makonede Here is the URL generation algorithm

@cairdcoinheringaahing Oh ok

Does every language need an answer there?

caird coinheringaahing

@user If that's the natural representation of integers in your language, yeah

@user No, but ones that have weird I/O methods do :P

Makonede

@user thanks!

user

Are you implyingi Stack Exchange is weird? :(

caird coinheringaahing

8:52 PM

@user You just asked if you could "take input as a stack composed of n empty stacks". It's kinda weird :P

user

I know, that was kinda the point of this language :P

Makonede

@user by the way, i'm not great with JS so I can't make much out of it, but managed to find the function in Charcoal's code (I remember seeing that most Charcoal programs also output the SE Markdown with -l). Thanks anyway :)

user

Although I could probably make it weirder

@Makonede Good to hear

caird coinheringaahing

@hyper-neutrino It's annoying that none of the auto-range quicks make the link operate on the range, I feel convinced there's some way to get rid of the R :/

hyper-neutrino

yeah, i'm almost certain there has to be some way to get this to 2b

user

9:00 PM

@RedwolfPrograms I wonder what happens if someone stars this (current) message - then a message about a message about starred messages that got starred would get starred.

Wezl

@user since that message refers to itself, it forms a cycle (infinite "about starred messages")

user

@Wezl Ah, so if you star my message, it can be used to confuse bots. Very nice!

Wezl

only if there are meta-level counting bots

user

Well, if there any, don't you want to stop them?

rak1507

9:24 PM

FGITW effect is so real

+3 for my shitty solution to that latin square challenge already lol

user

Okay, I'll downvote you :P

rak1507

noooo

user

It's alright, I couldn't even if I wanted to - my vote's locked in.

rak1507

ah

+5 for that jelly solution... grr

user

I think it was more because it was so much shorter than caird's solution

rak1507

9:28 PM

yeah good point

caird coinheringaahing

Also it "exposed" the trick

rak1507

not much of a trick to expose :P

user

I mean, not all answers are using that exact approach, although everyone has pretty much the same output

@rak1507 <

caird coinheringaahing

Arnauld and HN were, I think, the first two of the different approaches, so I can understand them getting upvotes

Fair enough, didn't see your Scala answer

user

But yeah, it's still extremely similar

I think xnor had the first flat one

Redwolf Programs

Crazy weather here

Skies were practically black when class finished. Started walking out to the busses then cue five minutes of golf ball sized hail. Get on the buses and it's over. Now the skies are blue and it's been ten minutes.

rak1507

codegolf.stackexchange.com/questions/70635/… go upvote neils answer for this question it's good and deserves more than 2 upvotes (or don't I guess, I can't tell you what to do)

caird coinheringaahing

@rak1507 Only if it switches to mathjax, <sup> based powers hurt my eyes :P

@user You just updated your answer to be the same as xnor's about 2 seconds after they posted theirs :P

user

@cairdcoinheringaahing Yeah, I'm reverting so there aren't duplicates

It's really AZTECCO's answer

Redwolf Programs

9:53 PM

I think I finished my new language! (Not Ash)

It's called 10IPL

It stands for 10 Instruction Programming Language

rak1507

aw, I was hoping PL was prolog

caird coinheringaahing

~~Is it a 10 instruction language?~~ ninja'd

Redwolf Programs

It's a really simple machine code/assembly thing, with - you guessed it - ten instructions

rak1507

what are they

caird coinheringaahing

"push 1, 2, 3, 4, 5, 6, 7, 8, 9" and "add"

rak1507

9:54 PM

lol

Redwolf Programs

Zero, Increment, Rotate, Print, XOR, NOR, Input, Read, Write, and Jump

user

The first 8 are for brainf*ck, and the last two are the constants "Fizz" and "Buzz"?

rak1507

hah

user

@RedwolfPrograms Jump? Do I smell GOTOs?

Redwolf Programs

You do

caird coinheringaahing

9:55 PM

@RedwolfPrograms How does Jump work without a Label command?

rak1507

presumably to an address

Redwolf Programs

You write the destination pointer to a register

(two registers actually since it's 8 bit)

caird coinheringaahing

Please tell me this is implemented by your minecraft computer

Redwolf Programs

It comes with a full 64 KiB of RAM, and all the registers you'll ever need (8, including the two IP ones)

@cairdcoinheringaahing That's what it's designed for, but not implemented there yet

I'll upload it to GH, just a sec

caird coinheringaahing

Also, FYI @RedwolfPrograms, votes are still coming in the RO election :P

The gap between you and Adam is now smaller than the gap between you and Lyxal

Redwolf Programs

9:58 PM

:(

rak1507

not really any surprises for the top 5

apart from bubbler, maybe

caird coinheringaahing

I'm surprised that Bubbler's beating me, given the votes on the nominations page

rak1507

if I had over 10K I would've self nominated and beat you all :P

rak1507

@cairdcoinheringaahing if I had to guess I'd say most answers will use that which is not particularly interesting

Redwolf Programs

I made to many commits really quickly to get some interpreter files added and now it's quota'd

cjquines

hi, meta question: how reasonably efficient should code golf solutions be expected to be when it's not fully specified? specifically wondering about this question but also in general

rak1507

@cjquines not at all (unfortunately)

caird coinheringaahing

10:14 PM

@cjquines Welcome to TNB! Unless stated in the question, answers can be as inefficient as they want

rak1507

as long as you can 'prove' that it produces the correct answer even if it would take several universe lifetimes, it's valid

Redwolf Programs

@rak1507 Unfortunately? Insanely inefficient solutions are half the fun of code golf!

rak1507

personally I never upvote those solutions though :P

cjquines

hm so the question states “Your program should be able to handle inputs 0≤n<100,000 at least.” i guess i’m not sure what “handle” is supposed to mean here

Redwolf Programs

I upvote ones just because they are inefficient. I love adding two numbers in O(n^n^n)

caird coinheringaahing

10:15 PM

We do have the restricted-complexity and restricted-time tags if you want to write a challenge where answers must finish within a reasonable amount of time

cjquines

like… it can handle them, it just takes like ten minutes by my estimate

caird coinheringaahing

@cjquines "handle" = "don't error"

cjquines

i see

Redwolf Programs

It just has to work in theory

cjquines

sorry ppcg is scary and posting answers is scary D:

Redwolf Programs

10:15 PM

Don't worry, we don't byte

rak1507

posting answers gets less scary with time dw

Redwolf Programs

hah get it? byte?

cjquines

yeah haha

eyeroll

caird coinheringaahing

@cjquines If you had a program that used for(i<99) {do thing}, that wouldn't handle inputs greater than 99 (very basic example), so wouldn't work

rak1507

I feel like I recognise you from somewhere but idk where lol

Lyxal

10:17 PM

@cjquines here's how to do well on cgcc

Redwolf Programs

I think 10IPL is turing complete, if you ignore the maximum of 64 KiB of storage

caird coinheringaahing

@cjquines I'd recommend finding some older, less active questions to start on, rather than trying to quickly rush out an answer to something recently posted. That way, you've got the time to enjoy the golfing rather than worrying :)

Wezl

@Lyxal ruuuuude

cjquines

i did not have to click the link to tell what it was xp

caird coinheringaahing

@Lyxal Yeah, let's maybe not rickroll new users just yet :P

rak1507

10:18 PM

@cjquines you already know lyxal well

Redwolf Programs

The trick is to download lots of userscripts

caird coinheringaahing

Getting rickrolled should be like a privilege you get at ~50 rep, along with commenting :P

Lyxal

@cairdcoinheringaahing gotta let new users know what they're dealing with

Redwolf Programs

Getting rickrolled by Lyxal is what makes the TNB the TNB
