The Nineteenth Byte

CMC: print the sequence. only print n when if the first n can perfectly divided by first number of n then n is divided by first num of n and repeat until the length of n is 1.

i can't tell if i'm having a stroke or u are

do you mean 'first digit of n' when you say 'first number of n'?

@Rɪᴋᴇʀ first number of n is first digit of n

(ignoring when divide by 1 it runs in infinite loop)

if the first digit of n perfectly divides all of n? and you repeat that scenario on the new quotient?

if the n perfectly divides all of first digit of n?

then n is n divided by first digit of n

???

hit enter not shift-enter in textbox

12:43 AM

@Rɪᴋᴇʀ wdym?

i deleted the message since i hit enter accidentally

ok

do that.

@Fmbalbuena what does this mean?

that isn't a valid english sentence

like if n % n[0] = 0 then n = n / n[0] else don't

okay that makes more sense

@Rɪᴋᴇʀ are you implementing?

in a minute i'll work on it, yeah, why?

@Fmbalbuena there's no reason to specifically call out forbidden loopholes - unless you have some to suggest, that is. you don't have to specify forbidden loopholes it's just a good idea if there's any major ones

@Rɪᴋᴇʀ more than a minute...

why are you so desperate for my answer dude? chill

i'm pretty sure that sequence can be reduced to something simpler to check against. since it could be broken down to some form of floor(x/10) in some cases, or smth like that

12:55 AM

@Rɪᴋᴇʀ ?

it also seems familiar as a problem statement (not quite this one but there's some sort of sequence derived from first digits that i can't remember right now)

i mean there's probably some easier way to determine if a number meets that criteria recursively than just doing that recursively

solve without golfing

this sounds like your homework now dude

also, what does 'no, not because different' mean on the sandbox comment? it's not the same challenge but i believe that sandboxed post is just a more specific form of the one I linked

@Rɪᴋᴇʀ I'm not at homework.

and that there's not really any new optimizations that could be applied to the smaller one

actually nah this goes as a comment

@Fmbalbuena this is also an annoying thing to test without a set of test cases. part of why i'm beginning to think there's a better way to do this is how rare numbers that meet those criteria seem to be

1:00 AM

@Rɪᴋᴇʀ the numbers is rare.

yes that's what i just said

first terms of this sequence is obviously 0, 1, 2, 3, 4, 5, 6, 7, 8, 9

but what if after 9

(ignoring multiples of 11 and 10, as well as anything starting with 1)

@Rɪᴋᴇʀ yeah

i consider the rules as given to mean that anything that starts with 1 immediately passes the test, due to looping forever

1:02 AM

@Rɪᴋᴇʀ yeahly

and dividing by 0

dividing by zero should never occur with the rules as given unless i'm missing something

n = n/n[0] is float division and unless you choose to keep leading zeros (which would mean everything instantly breaks due to divide-by-zero errors)

ok so do it now.

paste.ee/p/G5Vgt

here's a list of the appropriate integers in the range 1-1000. i'll send my python code once i'm happy with it

really?

some starts with 1

don't do

you count 1 as being part of the sequence, which implies that 10, 11, etc. also are part of the sequence

also, 0 does not count as part of the sequence unless you've found a way to divide by 0

1:06 AM

@Rɪᴋᴇʀ not part of sequence.

@Fmbalbuena .

@Rɪᴋᴇʀ .?

the message i replied to lists 1 as part of the sequence

@Rɪᴋᴇʀ no, no, NO.

would you like to phrase this in a different way then

1:08 AM

@Rɪᴋᴇʀ please do it without starts with 1.

so 1 is a special case and doesn't count as starting with 1?

prints when the length of a number is 1.

but you wouldn't include 10 or 11 as a member of the sequence?

(except 1 because the length of a number is 1.)

1:19 AM

pretty sure no number only divisible by any single-digit prime (2,3,5,7) could ever meet this criteria (outside of those numbers themselves)

unless i'm tripping and missing something stupid

@Fmbalbuena can you give a single example of a number that meets these criteria? (more than the single digit ones)

I did my original code wrong so I'm not sure there even is one unless i'm missing something this time.

Q: Worst case of Slowsort

Background Slowsort is an in-place, stable sorting algorithm that has worse-than-polynomial time complexity. The pseudocode for Slowsort looks like this: procedure slowsort(A[], i, j) // Sort array range A[i ... j] in-place. if i ≥ j then return m := floor( (i+j)/2 ) ...

1:35 AM

@Rɪᴋᴇʀ undesrtand?

understand what

oh there is no more than 1 digit number in my theory.

yeah i realized i was being stupid

because imagine the first digit and dividing to get one. is there way to get two?

all numbers when doing any division will eventually collapse to something coprime with that number

1:37 AM

Answer: Impossible

it would be more interesting if you stopped at any prime (assuming some prime checking function)

CMC print the sequence. only print n when if the first n can perfectly divided by first number of n plus 1 then n is divided by first num of n and repeat until the length of n is 1.

only diff is n can perfectly divided by first number of n plus 1

Implement xorshift128+ I don't have time to finish writing this draft at the moment.

I swear NP/SP post faster than the button loads

Quick searching in esolangs gives a bunch of results that only allow 1-char variables, nothing related to long variable names

3:52 AM

though I can imagine a language where the variable name defines how it is computed, and then you need to use that name to reference it later

and reassignment trick doesn't work because reassignment only results in longer names

Or is it useless?

4:27 AM

Flax

why do you like the same name as my brother (he suggested it lol)

It's the coolest sounding

hyper-neutrino

it's also one of the only two that i immediately know how to pronounce

@RedwolfPrograms I've beaten NP before

@PyGamer0 ~~because lyxal is your brother~~

ok flax it is ig

Flux could also be good, your choice

OooOoOo New tacit language?

flux lol

flex?

FLOX

fl[a-z]x

6:16 AM

fl\wx

/fl\wx/i

It's a regex that matches fl followed by any letter, number or _, followed by an x.

@Bubbler No pressure, it'll probably be fine if we finish some after 1st december

Since we can post preprepared ones during that time

CMP: Should i create the codepage first or the language?

@PyGamer0 if you want to go the Vyxal route, where the codepage is fairly meaningful (not just random letters), then create the language first and make the codepage fit around it

otherwise, it's fine to make the codepage first

9:13 AM

if i am right Try it online! just adds 1 to 1 and subtracts 1 from that and muliplies 1 to that outputing 1

so 2+ should give 4

ok i think i understand a little of jelly's tacit system

Are you learning Jelly or trying to remake it?

@PyGamer0 tbh I found the cheatsheet easier to understand than the tutorial

trying to make sense of it as if it were intuitive just confused me

but a system of rules? that I can learn!

I didn't get too far into it

And looking at it now, it makes no sense at all

@lyxal lol

@lyxal you just made a fizzbuzz demo and nothing else

@PyGamer0 I swear I also had more notes on paper about it too

i thought of a tacit system, then i realised its just jelly's but worse

Welcome to the club

here was my horrible first attempt

I had no clue what I was doing

@lyxal did you ever make anything after that?

10:45 AM

@PyGamer0 nothing explicitly tacit

@lyxal so you have implicit tacit languages?

@PyGamer0 stack based is technically tacit

CMQ: Is English tacit?

no

why?

10:54 AM

english refers to its 'arguments' with pronouns and things like 'the'

'the cat sat on the mat' - not tacit
'cat sat mat' - maybe tacit?

yeah the mat sat on the cat

makes sense

lol

11:08 AM

pro-drop natural languages are tacit then, clearly

@UnrelatedString like what?

cat mat sat hell well

...went to look up a good canonical example of pro-drop and til that the pro stands for pronoun
obvious in retrospect
but all along i thought it was like
pro-drop versus anti-drop

lol

Ok, 11260 bytes in my language "99 bottles of beer on the wall"

The way the language works:
If the program is the text of "99 bottles of beer on the wall", print the text of "99 bottles of beer on the wall"
Otherwise, interpret it as golfscript

@tjjfvi program

So the text of "99 bottles of beer on the wall" is a beer-shaped quine in it

@tjjfvi not beer shaped; no stars.

Exactly

yeah

but the program shape doesn't look like beer

I thought it meant anything

I still hold that my program is beer-shaped, as it has been shaped (read: molded, formed) by the beer

@tjjfvi shape must look like beer like: bottle of beer or glass of beer.

You can't substantially change the challenge rules after answers have been posted

@tjjfvi They pretty clearly don't mean "shaped by beer"
