why

lyxal

because rewrite

Fmbalbuena

00:33

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.

Rɪᴋᴇʀ

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

4

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

Fmbalbuena

@Rɪᴋᴇʀ first number of n is first digit of n

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

Rɪᴋᴇʀ

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

Fmbalbuena

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

then n is n divided by first digit of n

???

Rɪᴋᴇʀ

hit enter not shift-enter in textbox

Fmbalbuena

00:43

@Rɪᴋᴇʀ wdym?

Rɪᴋᴇʀ

i deleted the message since i hit enter accidentally

Fmbalbuena

ok

do that.

Rɪᴋᴇʀ

@Fmbalbuena what does this mean?

that isn't a valid english sentence

Fmbalbuena

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

Rɪᴋᴇʀ

okay that makes more sense

Fmbalbuena

00:47

@Rɪᴋᴇʀ but don't if the first digit is 1

else runs in infinite loop

Fmbalbuena

@Rɪᴋᴇʀ are you implementing?

Rɪᴋᴇʀ

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

Fmbalbuena

@Rɪᴋᴇʀ more than a minute...

Rɪᴋᴇʀ

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

Fmbalbuena

00:55

@Rɪᴋᴇʀ ?

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

Fmbalbuena

solve without golfing

Rɪᴋᴇʀ

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

Fmbalbuena

@Rɪᴋᴇʀ I'm not at homework.

Rɪᴋᴇʀ

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

Fmbalbuena

01:00

@Rɪᴋᴇʀ the numbers is rare.

Rɪᴋᴇʀ

yes that's what i just said

Fmbalbuena

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

but what if after 9

Rɪᴋᴇʀ

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

Fmbalbuena

@Rɪᴋᴇʀ yeah

Rɪᴋᴇʀ

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

Fmbalbuena

01:02

@Rɪᴋᴇʀ yeahly

and dividing by 0

Rɪᴋᴇʀ

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)

Fmbalbuena

ok so do it now.

Rɪᴋᴇʀ

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

Fmbalbuena

really?

some starts with 1

don't do

Rɪᴋᴇʀ

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

Fmbalbuena

01:06

@Rɪᴋᴇʀ not part of sequence.

Rɪᴋᴇʀ

@Fmbalbuena .

Fmbalbuena

@Rɪᴋᴇʀ .?

Rɪᴋᴇʀ

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

Fmbalbuena

@Rɪᴋᴇʀ no, no, NO.

Rɪᴋᴇʀ

would you like to phrase this in a different way then

Fmbalbuena

01:08

@Rɪᴋᴇʀ please do it without starts with 1.

Rɪᴋᴇʀ

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

Fmbalbuena

prints when the length of a number is 1.

Rɪᴋᴇʀ

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

Fmbalbuena

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

Rɪᴋᴇʀ

01:19

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 ) ...

Fmbalbuena

01:35

@Rɪᴋᴇʀ undesrtand?

Rɪᴋᴇʀ

understand what

Fmbalbuena

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

Rɪᴋᴇʀ

yeah i realized i was being stupid

Fmbalbuena

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

Rɪᴋᴇʀ

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

Fmbalbuena

01:37

Answer: Impossible

Rɪᴋᴇʀ

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

Fmbalbuena

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

Redwolf Programs

I swear NP/SP post faster than the button loads

Bubbler

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

Bubbler

03:52

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?

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

Since we can post preprepared ones during that time

PyGamer0

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

pxeger

@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

PyGamer0

09:13

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

PyGamer0

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

emanresu A

Are you learning Jelly or trying to remake it?

pxeger

@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!

PyGamer0

@lyxal lol

@lyxal you just made a fizzbuzz demo and nothing else

lyxal

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

PyGamer0

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

lyxal

Welcome to the club

here was my horrible first attempt

I had no clue what I was doing

PyGamer0

@lyxal did you ever make anything after that?

lyxal

10:45

@PyGamer0 nothing explicitly tacit

PyGamer0

@lyxal so you have implicit tacit languages?

lyxal

@PyGamer0 stack based is technically tacit

PyGamer0

CMQ: Is English tacit?

rak1507

no

PyGamer0

why?

rak1507

10:54

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

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

PyGamer0

yeah the mat sat on the cat

makes sense

rak1507

lol

Unrelated String

pro-drop natural languages are tacit then, clearly

PyGamer0

@UnrelatedString like what?

cat mat sat hell well

Unrelated String

...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

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

Fmbalbuena

@tjjfvi program

tjjfvi

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

Fmbalbuena

@tjjfvi not beer shaped; no stars.

tjjfvi

You didn't specify what beer-shaped meant

beer shaped means bottle beer shaped.

Fmbalbuena

yeah

but the program shape doesn't look like beer

tjjfvi

When did "beer-shaped" become "shape must 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

Fmbalbuena

15:40

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