@Anush APL, 19: c/⍨∧⌿2≠⌿c←6⊥⍣¯1⍳6*5 – put ⍉ on the far left for beautiful output: Try it online!

@Anush stupid and simple approach: ato.pxeger.com/…

@Anush APL, 16: c⌿⍨∧/2≠/c←↑,⍳5⍴6 – beautiful out of the box: Try it online!

@Anush aw that's too complex for LMBM, guess I'll do it in js instead

nice

anyone for python?

@Anush Probably shortest to use PynAPL and do it in APL :-Þ

@Anush Pip, 26 bytes:

`(.)\1`NI_FI J*$CP:[,5]RL5

@Adám :)

@DLosc 24 bytes: Try it online!

@Anush Do you want an explanation?

damn I've not flexed my golfing muscles in far too long, I'm struggling

@Anush JS, 132 bytes: Try it online!

@Anush Here's a first stab at it: Python3, 100 bytes

But itertools is never the answer [citation needed], so there may be a shorter way to do it.

@Anush JS, 125 bytes: Try it online!

I was trying to be too clever and didn't notice that 6**5-1 is longer than 7775

Darn, that significantly less than an order of magnitude longer than APL.

I'm pretty sure I can golf n.toString(6).padStart(5,0) further, I'm just not sure how

@Adám I can add 35 bytes of whitespace if it makes you feel better :P

:-D

@Skidsdev I actually don't think so, the shortest I can get using a recursive function is around 10 bytes longer :/

And I doubt anything'd be shorter than doing it with recursion or with toString and padding

Darn. I know my usual solution for golfing .toString would be +"", but that doesn't work here because I need to pass the base

Oof, generator functions are not the way. 126 bytes: Try it online!

@DLosc nice although I agree about itertools

@RedwolfPrograms (g=(x,s="")=>s[4]?s:g(x/6|0,x%6+s))(n) is my current approach for (un)golfing it (38 bytes, vs. 27 for the original)

Does anyone know a closed form for the number of such arrays?

@RedwolfPrograms Kind of ironic that it looks golfier just because it has short names and symbols

Yeah. At least there's no String.fromCodePoint needed here :p

hm, (+c)@&~|/=':c:!5#6 in ngn/k but I'm sure it can be improved

I was gunna try it in C# but y'know what? I value my sanity today

PSA: Tomorrow's BMG, so don't forget to draft.

Or today I guess, depending on your timezone.

@AaroneousMiller I don't know what that means

It's a new chat event we started recently

Biweekly Mini Golf

chat.stackexchange.com/rooms/info/240/…

Everyone posts a bunch of CMCs, and we all solve them

(CMC = Chat Mini Challenge)

that sounds awesome, unfortunately it falls right during my commute to work and morning standup :(

:/

We'd tried to rotate the time it took place more often, but it got too confusing and nobody would show up

Being active in PPCG (or CGCC now I guess) was a lot easier when I lived in the UK

It's every other week, and on alternate weeks it swaps a.m. and p.m. So you may be able to make it on November 3rd. (That's when I can make it.)

:/ I have D&D on wednesday evenings

^^ here's an example

Maybe we could try experimenting with either longer BMGs, or doing something like short 20m ones throughout the day?

For me it's either 8 AM or 8 PM, so It's either in the evening when I'm doing nothing, or in the morning when I'm at work and I do it anyway.

I think the scheduling is a pretty big issue right now, a not insignificant number of people can never make it

yeah it's 8/8 for me too. I usually work from home on Wednesdays, tomorrow just happens to be an exception

But speaking of scheduling conflicts, I have to go now :p o/

so most of the time I should be able to make the 8am ones

o/o

Likewise, time for the commute home. Feels good to be back though! Nice to see some familiar faces and some new ones.

@Skidsdev It's Tuesday evenings, actually

(Also: sounds fun!)

@DLosc I have D&D every other tuesday, so that might work, depending on where it falls in EST

@Anush Non-itertools, Python 3.8, 92 bytes

@DLosc very nice

And -1 byte to the itertools version if the digits are allowed to be strings

I don't understand python. bpa.st/T7DQ solves my puzzle but how is prefix+(x,) allowed?

+ concatenates tuples, and (x,) is the syntax for a tuple that contains the single element x

The single-element tuple syntax couldn't be (x) because that's just a parenthesized expression

I thought you could concatenate lists but not tuples?

you can do both just not mixing them

ah..is it linear or constant time in python?

With that said, you can save the comma by... using lists instead of tuples ;)

@Anush With respect to which variable? The original challenge asks for constant output, so it's by definition constant time

Oh, you mean concatenation

yes

I imagine it's linear, but I don't know

if I concatenate two tuples of length 1000 each does it take 2000 operations?

@pxeger would be the one to ask. He's dug into the internals of the CPython code far more than anyone else I know.

(The phrase "two tuples" sounds like it ought to be part of a tongue twister...)

tio.run/##K6gsycjPM7YoKPr/…

so yes, it's linear

@rak1507 thanks!

although it's confusing because the time doubles when you multiply the input length by 10

I am trying to understand oeis.org/…

what does it mean by (1+x)/(1-4*x) ?

taylor series coefficients

(in other words it says "expansion of (1+x)/(1-4*x)" because it's the polynomial expansion of that rational function, albeit you can't really expand it to a polynomial because it'd have infinite terms)

Protip: don't try to understand everything you see on oeis pages

Every time someone tells me I put a no-no word in a comment, I'll just point this code out to them :P

GPT-3 has the ability to write somewhat agro comments in its code

I don't have the sample anymore, but it was when I was trying to solve Bubbler's animal river crossing challenge using AI

Nice, do you have examples?

> I don't have the sample anymore

I think that should answer your question.

Oh I sent my message before you sent that lol

Or maybe I just somehow skipped over that entirely

@user Just use the navy seal copypasta :P

@user That code looks like it'd be controlling a robot of some sort...robot uprising coming soon?

If so, I'm not too worried with GPT-3 as their leader

Yeah, it's a rival team's code

Don't worry, looks like they suck at it though :P

Why does this have an undelete vote? Doesn't seem to have been edited to become okay

possibly a misclick

CMC: make a spooky qr code

QR codes are inherently spooky

@user Should be a rickroll

@lyxal you are now legally obligated to think a new thought in ~4 hours

@Wezl well it's not like I already do that for two discord servers every day

Good, just reuse those thoughts and repost them here :P

I'm going to arrange a bunch of apples and slices of bread in a way that they can perform turing complete computation

I call it a food processor

@user that's what I did yesterday

I've been doing that sort of thing since March
