CMC: given a list of nonnegative, pretty print the list of nonzero indices and their values, with the lists lining up visually, and the zero indices / values place being taken up by .... Example: (1 indexed) [0, 0, 5, 0, 11, 23, 0, 0, 0, 0, 0, 7] => ... 3 ... 5 6 ... 12\n... 5 ... 11 23 ... 7

the exact format is flexible, as long as the lines never desync (each index is aligned with its value)

and yes you may 0 index

thejonymyster

ooh yay

Dannyu NDos

Outputs a trailing newline but whatever

thejonymyster

totally fine

Bubbler

does it handle alignment?

thejonymyster

D:

tbh its definitely a "two challenges in one" type challenge

i suppose the more interesting one being just the alignment one

so thatd be like, "given two lists..."

instead of getting the indices as the other list

Dannyu NDos

Can I left-align?

thejonymyster

yea however you wanna align is fine

kind of a fast and loose spec srry i didnt wanna spend that long wording it for a cmc :P

no clue if it counts

thejonymyster

nah the idea is to replace the 0 spots with a ..., see example

definitely aligned tho so good job there

lyxal

04:38

@thejonymyster exactly 3 dots?

Or is there no upper limit on the number size?

thejonymyster

the string ... :P

if youve got a better cmc feel free to post it xd

lyxal

So there's an upper limit on number size?

Because a 4 digit number is gonna desync the output

thejonymyster

oh im sorry i see the confusion

lyxal

@thejonymyster no, you're thejonymyster

thejonymyster

youre right im not sorry

but i am going to clarify :-)

as soon as my. internet stops attacking me

thejonymyster

are we back? am i connected? :P

lyxal

@thejonymyster uhh no, still looks like you're thejonymyster

thejonymyster

nice

the idea is just that each index is aligned with its associated value

not necessarily that they all have the same exact spacing

thejonymyster rolls sloppiest cmc ever; asked to leave chat

so 1 2 ... 3 4\n1 10 ... 100 1000 is acceptable for example

promise im not making changes as i go this was always my intent ^_^ (innocent)

Dannyu NDos

Wait, I put x!i and i!x swapped.

A: Sandbox for Proposed Challenges

Obfuscated bananas In this challenge, your task is to print the string banana, case insensitive, to STDOUT (or an acceptable alternative) in the most obfuscated way. +1 VTC! No objective winning criterion! Wrong! I now have an objective winning criterion! Let the reporter edit distance of \$a...

The Empty String Photographer

Yes, underhanded has just been made objective.

mousetail

Drop the underhanded and make it a code challenge

There is no obfuscation aspect

Also PHP and any language with implicit output will score 0

Also not sure if your edit distance is even computable in polynomial time

The Empty String Photographer

08:57

@mousetail is print("banana") or print(chr(98)+chr(97)+chr(110)+chr(97)+chr(110)+chr(97)) more obfuscated?

Although if you’re decent at python they’re both not that obfuscated.

mousetail

You wantet to minimize the edit distance though right?

Not that it matters, in either case the real goal is edit distance, not obfuscation.

The Empty String Photographer

09:14

@mousetail sorry that was a mistake in the post, I wanted to maximise it.

mousetail

@TheEmptyStringPhotographer The maximum score will be 6 and it will be trivial to get the maximum score

Minimum Escaping open-ended-function Your task is to write 2 functions/programs. They may share code.

@AlanBagel I'm a tad late (lot late) but happy age++ :p

noodle man

somehow simultaneously the best and worst way to say happy birthday

mousetail

age++ or ++age?

lyxal

age -=- age / age

mousetail

On your birthday your age has already incremented right? So it should be ++age

lyxal

depends when you send the message

the ++ might be delayed if it isn't exactly time

Dannyu NDos

11:59

As stated aptly in Steve Oulline's How Not to Program in C++, "If a programmer writes a++++ in a code, they must be jailed."

mousetail

what about ++a++

Dannyu NDos

That still sucks, but the programmer pays a fine instead.

lyxal

--a++

Dannyu NDos

That sucks intermediately; the programmer loses their certificate.

mousetail

Noob programming: a-1. Pro programming: --a++

wonder if the compiler is smart enough to optimize both to the same assembly

Dannyu NDos

12:04

What if a isn't an integer?

lyxal

@DannyuNDos jokes on them I don't have a certificate

Dannyu NDos

Well, I judged them like this because, in South Korea, disqualification is an intermediate penalty between jail and fine.

lyxal

@DannyuNDos I keep reading Steve Oulline as Steve Jobs

Dannyu NDos

Confiscation < Detention < Mulct < Fine < Qualification suspension < Disqualification < Jail without labor < Jail with labor < Death penalty, according to Korean criminal laws.

mousetail

But jail with labor would allow Lyxal to program again which would be unacceptable

@DannyuNDos What's the difference between "mulct" and "fine"?

user

Does anyone know why both my shift keys may have stopped working?

They do still work, but only intermittently. If I let them "rest" for a few hours, they're more likely to work, and after a few minutes of use, they go back to working maybe 1 times out of 30

Ginger

membrane keyboard?

user

I've had to remap capslock to shift, and that does work, so I don't know what's up

This is the keyboard built into my laptop (an HP, if it matters)

@Ginger Just googled it, I don't think so (membrane keyboard don't have much tactile feedback, right? My keyboard does have some travel and makes a bit of noise)

Ginger

can the keys kinda tilt?

user

Kinda, yeah

Ginger

it's probably membrane

user

14:22

Oh

Ginger

if it's a laptop keyboard then it almost certainly is

in that case, the likely culprit is damage to the weird plastic trace contact pad thingy that the keys sit on top of

user

Oh my bad I thought membrane keyboards had the kind of buttons you find on washing machines

@Ginger Any idea if that's something I could replace myself?

Ginger

@user that's awful to imagine lol

please tell me you haven't seen any keyboards like that

@user is this a laptop?

user

No I haven't, I just thought those existed based off the description on Wikipedia

@Ginger It is, yeah

Warranty ran out only a few months ago :|

Ginger

F

I doubt you can replace it then

and it could be any number of other problems besides that

user

14:25

Dangit

Ginger

I'd advise you take it to a computer repair shop and have someone who knows what they're doing look at it, instead of asking some cat on the internet :p

user

You're cheaper :P

Ginger

I also can't see your computer, and therefore my guesses are just that: guesses

user

Looks like replacement keyboard are pretty cheap on Amazon

Ginger

that works too, of course

user

14:27

@Ginger True true

I think my next laptop'll be a Framework, if the company continues going strong

Ginger

ah, Framework

their stuff looks great but it's so expensive

user

I could keep the same chassis for like a decade and swap out the CPU once or twice during that time

@Ginger Oh yes, the 16-inch model starts at $1600 even with the most minimal of setups

Ginger

I've actually been mentally designing a similar laptop that uses a Raspberry Pi Compute Module

it'd run a modified version of ChromiumOS

user

What'll you house it in?

Ginger

not sure yet

but since the CM4 has pretty much the entirety of the actual computer part, the motherboard would only need to have a power supply and I/O stuff

user

14:39

aaaaaaaa even the cheapest configuration that I can tolerate is $1750

DLosc

@thejonymyster I would argue that the knight is explicitly jumping, despite the fact that its move isn't orthogonal. In Xiangqi (Chinese chess), the horse has a similar (2,1) move, but it can be blocked if another piece is in the way.

Unrelated String

17:27

i'd argue that's a consequence of its (2,1) being defined as a sequence of (1,0) then (1,1), since it can't be blocked on a diagonal

you could define a (1,1)-(1,0) that can only be blocked on a diagonal :P

DLosc

@UnrelatedString Hm, fair

Unrelated String

although i do also feel like there's a certain extent to which knight moves are conceptualized as (2,0)-(0,1), at least in a popular capacity among laymen if not meaningfully to the game itself, in which case that would have to be a jump

mousetail

I can't edit answers (it says "An error occurred submitting the edit."). Are you able to?

seems like it's a general SE problem

thejonymyster

19:08

tbh im not sure why im worrying about the semantics of whether a knight is a jump technically. i should be aiming for the simpler option (face plam)

RE: this sandbox's rules... are "literals" a universal programming concept or does that run into avoid making assumptions about language features?

my gut is telling me its a bad idea to include but i dont know if im like, making sense as to why

lyxal

@thejonymyster imo it's not a clear cut. For programs that act upon their own source code, where do you draw the line between source and literal?

DLosc

@thejonymyster Probably not universal, I'd guess. At any rate, there are some languages that don't have literals, such as BF.

lyxal

Also, are pre-defined constants literals?

Some might say they're variables, others might say they're nilads (take 0 args, return 1 value) and some might consider them literals

Also

> Comments that can be accessed by the program are counted as literals

What counts as accessed?

Dannyu NDos

22:19

@RydwolfPrograms Mulct is for a misdemeanor. Fine is for a crime.

thejonymyster

@DLosc not having literals isnt an issue, since this is a scoring rule that only is affected by having them :P

@lyxal oh i didnt even see that bit oml. we need to have a default / 'things to avoid' about mentioning comments at all in rules tbh :P

ATaco

22:32

@thejonymyster What's a Brainfuck Literal?

thejonymyster

^^^

to clarify i guess since both of you brought that up; a language not having literals is one thing, i meant more like is it always clear whether something is / isnt a literal

which is something i definitely, absolutely was clear about when i first asked. for sure. dont even check :P

so more what lyxal was getting at

ATaco

My language parses 10 * 2 as the literal 20, so which is the literal?

Seggan

23:19

...

why dont you leave that till constant folding?

ATaco

My implementation of constant folding is not very good.

Neil

let me guess it can only fold constants like 111 that consist only of straight lines

ATaco

It can only fold 7 times before it gets too thick to fold again.

lyxal

23:39

just use a larger piece of constant paper

somewhere in the range of 1,219m (4000ft) long

then you can get 12 folds

ATaco
