@EriktheOutgolfer why doesn't this output 0?

nvm

used the wrong atom for subtraction

5:45 PM

@EriktheOutgolfer actual question now. Is there a builtin that returns the indices of x in y? "Hello", "WoHrled" => [2, 5, 4, 4, 1]

@cairdcoinheringaahing i@€?

i is find index

@ swaps the left and right arguments

and € does that for each char

That uses a quick, right? :(

yes. € and @.

I hate quicks.

You're going to have to use them if you want to do anything :P

5:55 PM

I'm trying this

why isn't there a nilad that returns the upper and lowercase alphabets joined?

good question, ask dennis

I can't ping him here can I? :(

nope, he's never been in here.

@cairdcoinheringaahing those golf

@EriktheOutgolfer what?

6:01 PM

quicks are sometimes golfier than no quicks

@cairdcoinheringaahing i@€ is your shortest option here

with reversed arguments it's iÐ€ no shorter

How can I shorten the string in this?

@cairdcoinheringaahing ...

or this

Why doesn't ØA;Øa work?

it does

unless you try to replace "ABC...xyz" with it

why?

6:10 PM

because then it indexes into the first part and then concats the second part

that makes sense. How do you change the operator precedence?

I don't think you can.

I don't think that's how it works either

rot13, 235 bytes

raw, pure Python

>< really

I can't do Jelly, but I can do Python!

6:22 PM

lol great

34 bytes

if Jelly were written in Python 2

6:42 PM

it's python 3

also you can easily compress this

@HyperNeutrino the chat with you and Dennis has been popping up on the side of my screen, I know what you did

> I know what you did

lol

but yeah ok.

please no cheat >_<

what is cheat

asking dennis?

6:50 PM

cheating isn't learning

lol

@EriktheOutgolfer it isn't any challenge. I'm trying (and failing) rot13

@HyperNeutrino well, I think that was just spoiling the answer...;)

ah ok :P

> Try to avoid spoilers. Don't quit too fast, and when you see a spoiler don't immediately click it, you won't practice this way.

6:52 PM

ah yes right.

not hard rule but, well, learning quality increases this way

true

hm we have no lvl3 students?

we should but inactivity is a bit of a problem here lately

true

totallyhuman

7:07 PM

mm sorry i haven't been here in a while

i really intend to learn jelly

well you can take your time

@EriktheOutgolfer that reminds me. Do you have any challenges for me so that I can practice quicks?

@cairdcoinheringaahing here's one

given a list of integers (e.g. [6, 1, 3, 7]) return something like this

[1, 1, 1, 1, 1, 1, 2, 3, 3, 3, 4, 4, 4, 4, 4, 4, 4]

x is banned

3 bytes with x

Presumably, the quick is to replace x?

x is banned so that you use quicks

also there's builtin for LR

@cairdcoinheringaahing

usage of ⁸, ¹ or ḷ is banned too...

7:36 PM

I've gtg rn but Ill work on it tomorrow

quickly before I go, does - do anything? I can't find it in the atoms or the quicks page
