@Adám wait a minute

before you post

@LeakyNun Why?

@Adám because it's a dupe

strangely this was active just now... codegolf.stackexchange.com/questions/87496/alphabet-triangle

@LeakyNun Really?

Well, I have it in 10 bytes of Jelly

I don't get it

13 mins ago, by Business Cat

So if I understand correctly, it's an n x n rectangle of the alphabet, with the top right triangle cut away

1:13 PM

I get that, I don't get the number one

@DJMcMayhem it's the same

@Adám can be achieved by starting at 1, then alternating incrementing by n-1 and 1, until you reach n^2

sorry starting at one, then adding n, then alternating between n-1 and 1

oh wait no it can't

@Adám SOGL, 12 bytes: ²Δ.n{ē.-I{KP

Jelly, 7 bytes: ²sµḣ"JF

1:18 PM

@Adám Eh good enough, 22 bytes :/

SOGL, 11 bytes after fixing a bug. If I had a proper counter variable then it'd be 9 or 8 bytes

24 bytes (for older CMC) why D:

10 bytes with taking input from the stack

alphabet CMC, SOGL, 11 bytes: ³Z*n;{KēImP (10”r added for easier testing as it expects input on the stack (could be <s>10</s> 9 bytes with a counter variable :/))

1:33 PM

Alphabet CMC, Jelly, 10 bytes: ²ØAṁsµḣ"JY

strawpoll.me/13770251

CMC: Find the LCM of the range [1..n], what I think I'm going to call the LCMorial

@Sherlock9 Test case?

Jelly, 4 bytes: tio.run/##y0rNyan8/z/o8LIc/f///xsaAAA

If I wasn't lazy and actually made the LCM operator for Gaia, it'd be 2 bytes

1:38 PM

@BusinessCat Dew it

I'm going to see if I can make a GCD function in Parenthetic and work up from there

I thought Gaia was basically complete by you don't even have LCM?

ಠ_ಠ

Nah far from done

I don't have it because I don't like to make operators that only work only one type/combination of types and I haven't figured out what else to put on it

@BusinessCat what I do with SOGL is I mix completely unrelated things :p - № is factorial, reverse array and reverse string on newlines

Yeah I have some completely unrelated things too

1:41 PM

Why isn't it negate :P

It says literally no

@totallyhuman in monospace the o looks like ! a bit :p

ọ is sign for numbers, trim for strings, deltas for lists

And multiset union/intersection are ranges when used with numbers

I used ± for sign lol

It's plus or minus duh :P

Why does reduce in Proton return a function ಠ______ಠ I can't even do this CMC

@totallyhuman I use that for negating, string reversing and arrays vecorize

1:45 PM

Oh ye I wanted to file an issue on that

Might as well do that considering neutrino is on vacation

Proton, 58 bytes if not for random interpreter bugs: n=>reduce((a,b)=>a*b/(g=(x,y)=>y?g(y,x%y):y)(a,b),1..n+1)

Someone answered a closed question!

Erik the Outgolfer

@programmer5000 because for him the question was still open

You know what stinks about trying to implement GCD in Parenthetic? I forgot that there's no modulo in Parenthetic ಠ__ಠ

Erik the Outgolfer

checks are only done client-side

1:50 PM

@EriktheOutgolfer what?

So... I could bypass the client-side validation to answer it now?

ಠ_ಠ

Erik the Outgolfer

no

ಠ_ಠ that's dumb

Then how did pizzakingme do it?

these look absolutely fine to me...

@totallyhuman because the question ain't symmetric

1:55 PM

If anyone wants to try to golf the grass thing then here is a simplified version I guess

1:58 PM

Beat Jelly by nearly half :D

lolwat

oh wait

i think i know why reduce is borked

@totallyhuman ಠ___ಠ

because reduce is part of functools in python3

@totallyhuman lol

still doesn't explain why it isn't just throwing a nameerror

2:05 PM

@totallyhuman because it isn't functools.reduce

@ASCII-only but why is a non-existent function not throwing

@totallyhuman Oh it exists

...then what does it do ಠ_ಠ

!!reduce = (function, array) => {
	list = list(array)
	if !list return 0
	while (len(list) > 1) {
		list[0, 1] = [function(list[0], list[1])]
	}
	return list[0]
}

what

what is that

2:07 PM

the implementation of reduce?

where

nvm i found it

ಠ_ಠ just use the built-in reduce function

this is overcomplicating things

@ASCII-only I don't see how that returns a function wtf

Not only a function but a function that returns a function that returns a function...

github.com/alexander-liao/proton/issues/3

There's another Proton bug bugging me

then bug neutrino about the bug with a bug report on the bug tracker

2:13 PM

Actually a few, maybe I'll blow up the issues page

wat

is bork

the way functions work is borked

i dunno

even more wat

owattf

that's for real?

.-. how could this happen

2:20 PM

wowza my android question's about to hit 4k views

well no

but it's at 3,644

that's more than pie got

Hallo

hi

hi

:O new main challenge

another alphabet?

wowza

oh this is nice

2:23 PM

I try to FGITW in Python :)

@ATaco userscript-request: Userscript which shows quality of chatroom by finding median length of last 20 messages

oh dude c'mon

;-; that's just range adjustment, no fair

@totallyhuman Yeah, you got me by 7 seconds, I got you by 7 bytes :)

@totallyhuman blows raspberry :-) - I gave you an consolation upvote

> that's just range adjustment

@totallyhuman isn't yours?

2:29 PM

@Mayube What?

@totallyhuman See the good part: We'll both be outgolfed by Rod :)

Q: Semi-Diagonal Alphabet

Given a letter of the English alphabet, your task is to build a semi-diagonal alphabet to the input. How to build a Semi-Diagonal alphabet? Brief Description: First, you take the position of the letter in the alphabet, P (P is 1-indexed here). Then, you print each letter until the input (incl...

code-golf string ascii-art alphabet

hey what's bitwise for n-1

@totallyhuman ~-n

dammit looks you got the optimal version

2:34 PM

Yay, I tried to golf yours and it was mine :)

@Mr.Xcoder have you used ARKit before for iOS?

trying to get 3D characters overlayed based on longitudes latitude

Nope, I didn't use it

I took a break from iOS dev a month ago

Is it normally allowed to use input() in Python 2 and expect the input like 'this'?

@BusinessCat Yes, you are allowed to use input() and wrap in brackets

@Mr.Xcoder what where does it say this

2:36 PM

I don't think you'll get shorter though

Unless the challenge allows

@Downgoat Why would it be a problem? I have used it in tons of answers, you are generally allowed to take input as a string.

@Mr.Xcoder The thing is for python AFAIK input() always returns a string so wrapping input in quotes is a different string

if you use a Lang where input is evald then that's different

@Downgoat Not in Python 2

Ok well if it is still a string of the language gets it with extra quotes it's a different stribg

2:40 PM

python 2 is allowed to take strings with quotes around it to save 4 bytes

that's about it

@totallyhuman 59 bytes :)

@Downgoat Input is evaled in Python 2

Braingolf is really bad at ASCII art stuff

@DJMcMayhem I thought everyone use python 3

But the question was specifically "is it allowed in python 2?"

2:48 PM

@Downgoat not for golfing

python 2 is better usually for golfing

python 3 is better for... just about everything else

Generally, yeah 2 is better. But sometimes new features in 3 are nice

(like splat)

When you do array-manipulation, 3 is much better for golfing

@Ruud Leaky doesn't like Python 2. — Mr. Xcoder 5 hours ago

@LeakyNun Am I wrong?

@Mr.Xcoder did I imply that?

2:53 PM

Not necessarily, more like you only do Python 3.

hmm

is exply a word

@totallyhuman no it isn't

:c

wow, Pyke has character range :c

dangit

charcoal feature-request: pls allow other degree cursor pivots

45 and 90 is so restrictive

2:58 PM

WHY DO PEOPLE RANDOMLY DOWNVOTE MY POSTS?

hmm?

@totallyhuman -1 for my Python answer (that happened 1 week ago too)

o0

why?

oh wait nvm that's what you're asking

it gets really annoying

mm

the ones without explanations are annoying

Erik the Outgolfer

3:01 PM

@totallyhuman they're the ones that can be done without storing anything

user image

yay pyth is better than charcoal

I think I can do better

@EriktheOutgolfer what?

Erik the Outgolfer

multiples of 45 degrees can be done with a constant direction among the 8 directions

right

but degrees like 15 and 30

Erik the Outgolfer

the others may need to alternate between directions, so they have to store a number or something and it's confusing when it changes or even an operator called "cycle state" may be needed

3:03 PM

quetion: what is the loop variable stored in

Erik the Outgolfer

and of course who ain't too lazy to implement that? :p

in charcoal

Erik the Outgolfer

@totallyhuman first free variable starting with ι and ending with θ cycling from ω to α

free = not used by any parent loop

@Mr.Xcoder No need to yell

Too late to edit, sry

Erik the Outgolfer

3:06 PM

yeah yelling is when something is repeated too many times and there's a reason for it

or it's just too intense

@EriktheOutgolfer oh thanks

i got somewhere

Well, I wrote modulo, gcd, and lcm in 388 bytes in Parenthetic (that will probably have to increase as I may need to rename gcd later on)

Erik the Outgolfer

@totallyhuman that extra byte is exactly to fix that issue

hrmm

But reduce was being such a pain in the butt that I'm taking a break from Parenthetic to work in a more human language

3:09 PM

@Sherlock9 nice!

@Sherlock9 you don't need reduce

Or maybe I mean a more humane language

@LeakyNun How do you get the LCMorial then?

Lists, my friend. They're a pain

@Sherlock9 no

just the same way as factorial

recursion

but instead of multiplication u lcm

Recursion sucks. Iterative is where it's at.

@EriktheOutgolfer @ASCII-only blasphemy has occur

@LeakyNun facepalm You know what sucks about this epiphany. I've already written LCMorial in this exact way in Racket before

Should have realized earlier XD

3:14 PM

@Sherlock9 lol

@Mr.Xcoder I mean you have over 9K rep so like -2 isn't like super big diff to your rep :P

@Downgoat I know, but you see your answer leading and then osabie gets upvoted and mine downvoted, and suddenly I have the second :0

⁺℅⁺ι⁶⁴ this bit is pissing me off

@Mr.Xcoder RIP

I couldn't get below 19 in Gaia

3:18 PM

@Downgoat Thanks. Good luck with ARKit

Erik the Outgolfer

@totallyhuman there's §αι too ;)

for half the size

@EriktheOutgolfer I think you have to add 1 for that to work

⁺§α⁻ι¹ is same byte count for my approach

rip

totally did not brute force

the return of the alphabet challenges is upon us

3:29 PM

And people like them. I had a very similar challenge in mind, but harder (compared to the new one)

@LeakyNun Having some trouble again: tio.run/…

LCMorial[6, 1] runs fine and every LCMorial before that. But after LCMorial[7,1] everything breaks

What is Parenthetic? The new brain-flak or so?

Something about a Parentheses Mismatch

@totallyhuman CMC: Output aBcDeFgHiJkLmNoPqRsTuVwXyZ

@Downgoat Ono where

@Mr.Xcoder no, the really really old one

3:34 PM

so long

@ASCII-only :o

I asked them to golf the hello world (and they managed to golf quite a bit :D), turns out it's actually pretty intuitive

:o I earned 3 tag badges today

untested really interesting looking code: print map(chr,sum(zip(range(97,122,2),range(66,91,2)),()))

3:36 PM

@totallyhuman wat

@StepHen PowerShell, 41 bytes -- -join(65..90|%{[char]($_,($_+32))[$_%2]})

With a little Python 3 editing, I get this

>>> print(list(map(chr,sum(zip(range(97,122),range(66,91)),()))))

3:37 PM

yay it works

58 bytes

shorter to hardcode :P

true, same for PowerShell

but that's boring

@StepHen Proton, 43 bytes: print(''.join(chr(i+32*(i%2))for i:65..91))

@BusinessCat what

oh nvm

nice

@BusinessCat Oh, that's a good idea. Saves 4 bytes by doing multiplication rather than selecting

-join(65..90|%{[char]($_+32*($_%2))})

Why doesn't it work to do i%2*32 instead?

I'm confused

3:42 PM

@LeakyNun Any luck?

@totallyhuman @BusinessCat @StepHen print("aBcDeFgHiJkLmNoPqRsTuVwXyZ") is much shorter

It seems * has higher precedence than %

4 mins ago, by totallyhuman

shorter to hardcode :P

o

4 mins ago, by AdmBorkBork

but that's boring

3:43 PM

@Mr.Xcoder Boring -1

Shorter +1

@BusinessCat hehe ninja'd you

PowerShell, 28 bytes -- "aBcDeFgHiJkLmNoPqRsTuVwXyZ"

@Sherlock9 could you comment the rest of the code?

Yeah, let me find it all

3:45 PM

print([[chr(x),chr(x).lower()][x%2]for x in range(65,92)])

@LeakyNun tio.run/##pVTNTsQgGLzzFBz5Eg/…

@LeakyNun Just checked: LCMorial[6, 7] is also not working

Mhm?

@LeakyNun Okay, but LCMorial[6, 8] and LCMorial[6, 9] works. May be some problem with 7

Cantor's unspeakables

CMC: Given an integer, return it multiplied by the golden ratio

Actually, 2 bytes: φ*

Well done +1

Welp, that's a constant Gaia doesn't have

05AB1E doesn't have it haha

lambda n:n*(1+5**.5)/2

python does not have it anywhere in stdlib

@LeakyNun And plain lcm(7, 60) works fine as well

Is it a bug?

3:59 PM

@Sherlock9 let me install a debug later

@totallyhuman yes, it's basically just $\sqrt{5}$
