@Mendeleev How did you type that in? I have to use U+200As if I want part of a word to be properly bolded

Mayube

@LegionMammal978 just surround the text with double asterisks

**this** becomes this

LegionMammal978

That doesn't work as just part of a word

wait wat

SE must have updated Markdown or something

wow

Mr. Xcoder

1:18 PM

Anyone, equivalent of [1:] in Pyth?

Except P_

Leaky Nun

@Mr.Xcoder >Q1

@Mr.Xcoder t

Mr. Xcoder

@LeakyNun Thanks

Leaky Nun

@Mr.Xcoder _P_

Mr. Xcoder

I needed a one byte equiv, thanks!

Leaky Nun

@Mr.Xcoder what is it for?

Mr. Xcoder

1:21 PM

0

A: Find all the Anagrams!

Pyth, 3 bytes t.p Test it online! Uses a slightly different approach than the other answer. Explanation t - Get all except for the first element, thing[1:] in Python .p - Get all the permutations

I tied 05AB1E and beaten the other Pyth answer

Oh, there must not be dupes/

Leaky Nun

@Mr.Xcoder no need to delete it... just add one byte

Mr. Xcoder

} I suppose?

Leaky Nun

{

but then it ties the other Pyth answer

Mr. Xcoder

Yes, it does not matter, I have P_.p as well.

Leaky Nun

what?

Mr. Xcoder

1:24 PM

That did not work, P_.p

because it has dupes

So I will use that

Ignore me

@LeakyNun Please remove the "Nope" now

Leaky Nun

@Mr.Xcoder nope.

Mr. Xcoder

Wow.

CMC: Given a string, reverse it, remove its digits.

Leaky Nun

vote to close as multipart

vote as unclear for lack of testcase

@Mr.Xcoder Pyth, 6 bytes: _-Q`MT

Mr. Xcoder

@LeakyNun Not multipart - You are given a String and must apply a certain algorithm consisting of two steps.

Leaky Nun

@Mr.Xcoder "reverse it" is a part, "remove its digit" is another part

I know it doesn't fit the standard meta definition of multipart

Mr. Xcoder

1:33 PM

It is a single algorithm.

A single task

Leaky Nun

@Mr.Xcoder the two steps are irrelevant

Shaggy

@Mr.Xcoder Japt, 7 bytes w k"%d"

Mr. Xcoder

@LeakyNun No they are not.

Leaky Nun

@Mr.Xcoder yes they are

Mr. Xcoder

CMC (reformulated): Given a String, return the reversed String with the digits removed.

@LeakyNun I disagree.

Leaky Nun

1:34 PM

@Mr.Xcoder let's agree to disagree

Mr. Xcoder

@LeakyNun Fine.

Leaky Nun

@Mr.Xcoder Jelly, 4 bytes: ḟØDU

@Mr.Xcoder will you undelete your post?

Mr. Xcoder

No

Leaky Nun

why not?

V. Courtois

have to ask (though i won't do it until tomorrow) : when I post my challenge back to the main, should I delete it from the sandbox?

Mr. Xcoder

1:40 PM

@LeakyNun That's because it's only one ~~digit~~ character different that the other one.

Leaky Nun

@Mr.Xcoder indeed.

@V.Courtois yes

Erik the Outgolfer

@V.Courtois yes

slow-internet-connection-ninja'd

V. Courtois

Heard it

thanks :)

both'

Jim

@V.Courtois See this answer

Mr. Xcoder

@V.Courtois But you should also delete its sandbox content, such that it frees up the sandbox a bit. Leave only the title and "POSTED", like [TITLE](link) -- POSTED

And then delete it completely

V. Courtois

1:43 PM

oh! not only delete?

Mr. Xcoder

No, not only. Also delete its content, except for its title

Erik the Outgolfer

≥2k users can see deleted posts so it would be a convenience for them

Mr. Xcoder

Those that have over 2k rep can see deleted answers, and it is bothering

V. Courtois

I see!

Mr. Xcoder

@EriktheOutgolfer I've been ninja'd again

V. Courtois

1:44 PM

high-internet-connection-ninja'd xD

Erik the Outgolfer

hmm...not precisely?

Leaky Nun

@EriktheOutgolfer how did you type ≥?

Mr. Xcoder

@LeakyNun ALT+> (on Mac at least)

Erik the Outgolfer

compose key + > + =

V. Courtois

xD

rekt

Leaky Nun

1:45 PM

rip windows

Mr. Xcoder

On windows it's num lock + ALT + > + = as I can remember

Erik the Outgolfer

1) Kaspersky Anti-Virus license has expired 2) it's slower than snail 3) you may get 3rd degree burns

@Mr.Xcoder on windows there's no builtin compose iirc

those are three reasons I hate Windows

Mr. Xcoder

@EriktheOutgolfer I hate windows too !

sorry only looked after reformulated cmc

Mr. Xcoder

@LeakyNun How does `MT work?

Leaky Nun

to hell with markdown

3

Mr. Xcoder

How. Does. It. Work?

Leaky Nun

@Mr.Xcoder It is equivalent to m`dT

or map(repr(d) for d in T)

Erik the Outgolfer

or m`dUT

Mr. Xcoder

1:51 PM

:38553536 How does m`dT work then?

@LeakyNun Ah, repr

Leaky Nun

and then the T gets converted to range

Ok

namely, UT

Give me a very easy task (not String manipulation) such that I can solve it in Pyth.

Erik the Outgolfer

1:53 PM

bitwise not (-x - 1)

Mayube

> not string manipulation

wuss

Mr. Xcoder

@EriktheOutgolfer ?

C'mon anything

Erik the Outgolfer

@Mr.Xcoder take an integer x negate it and subtract 1

Mr. Xcoder

@EriktheOutgolfer Negate integer, like 6 -> -6 or bitwise?

Erik the Outgolfer

bitwise

namely 6 -> -6 -> -7

Mr. Xcoder

1:55 PM

@EriktheOutgolfer Ok

Erik the Outgolfer

or -6 -> 6 -> 5

Mayube

@EriktheOutgolfer Braingolf: ..+-1-

Erik the Outgolfer

not really a cmc

Mayube

it is now

Erik the Outgolfer

closed as too broad

Mr. Xcoder

1:57 PM

What is the bitwise negation in Pyth, it's not ~?

Erik the Outgolfer

@Mr.Xcoder there's no builtin

Mr. Xcoder

Really :/

I said very easy task

Erik the Outgolfer

it's still very easy...

but just builtin is beyond very easy imo

Mr. Xcoder

I don't have a clue how bits work and really don't wanna know right now

Erik the Outgolfer

@Mr.Xcoder forget about bits, just calculate -x - 1

Mr. Xcoder

1:59 PM

I mean ~01010101 is probably 10101010, but...

Mayube

wait how does bitwise negation of 6 equal -6?

Business Cat

@Mayube Well then CJam, 2 bytes for input 1 for the actual work ಠ_ಠ: ri~

Leaky Nun

@Mr.Xcoder no, you don't need bits at all

Mr. Xcoder

@EriktheOutgolfer t_

Erik the Outgolfer

yep

or _h

Mr. Xcoder

2:00 PM

@LeakyNun How?

Leaky Nun

@Mr.Xcoder you just did it

Mr. Xcoder

@LeakyNun Bitwise.

Leaky Nun

what?

Erik the Outgolfer

bitwise solution isn't the shortest...

Leaky Nun

you can't exactly do it bitwise...

Mr. Xcoder

2:01 PM

@LeakyNun That's what @EriktheOutgolfer asked me to earlier

Leaky Nun

we only have and,or,xor

Mr. Xcoder

@LeakyNun ~x-1

Leaky Nun

@Mr.Xcoder he didn't ask you to use bitwise built-ins

@Mr.Xcoder no, -x-1

and that's far from bitwise

Mr. Xcoder

@LeakyNun The first time, not now!

Leaky Nun

what?

Erik the Outgolfer

2:02 PM

huh?

Mr. Xcoder

8 mins ago, by Erik the Outgolfer

bitwise not (-x - 1)

Leaky Nun

@Mr.Xcoder yes, - there.

Mr. Xcoder

This one: ~(-x-1)

Leaky Nun

@Mr.Xcoder that's just itself

Mr. Xcoder

FORGET IT

Leaky Nun

2:02 PM

the -x-1 is clarifying

@Mr.Xcoder wow

Mr. Xcoder

Like empty program?

Oh no, Q

Mayube

CMC: Given a number x, return x % n where n is the sum of the digits of the cube of x

@Mayube testcase?

@Mayube What's %?

Modulo

2:05 PM

modulo?

ah ninja'd

Leaky Nun

modulo!

Mayube

6 should output 6, 7 should output 7, 11 should output 3

Leaky Nun

@Mayube larger testcase?

Mayube

17 should output 0

246 shoudl output 21

@LeakyNun fancy doing it in braingolf? See if you can do < 13 bytes

Mr. Xcoder

Though I doubt I would have finished it.

Mayube

2:10 PM

@Mr.Xcoder learn braingolf :^)

Leaky Nun

@Mayube I don't see any string-conversion or base-conversion built-in

Mr. Xcoder

@Mayube NEVER.

Mayube

@LeakyNun it has neither, and needs neither for this challenge

@Mr.Xcoder yes

Erik the Outgolfer

umm that's actually repr(...)

Mr. Xcoder

2:16 PM

@EriktheOutgolfer that's what I want

Erik the Outgolfer

oh

Mr. Xcoder

And what is sum(sequence)?

Is it +[...)?

I mean +?

Forget the above.

I meant int(...) what is int(...)?

Anyone ^?

Leaky Nun

@Mr.Xcoder s or +F

@Mr.Xcoder s

Mr. Xcoder

@LeakyNun Danke

somebody likes german

Mr. Xcoder

Ich mocthe ein Antwort schrieben.

What do you think ^ ?

Leaky Nun

what does imperative mean?

Imperative programming

In computer science, imperative programming is a programming paradigm that uses statements that change a program's state. In much the same way that the imperative mood in natural languages expresses commands, an imperative program consists of commands for the computer to perform. Imperative programming focuses on describing how a program operates. The term is often used in contrast to declarative programming, which focuses on what the program should accomplish without specifying how the program should achieve the result. == Imperative and procedural programming == Procedural programming is a type...

Leaky Nun

2:24 PM

@Mr.Xcoder I mean, Pyth itself is imperative right

@V.Courtois 漢字=kanji

Mayube

Maybe I should make Kanjigolf

V. Courtois

あああああ~

Mr. Xcoder

@LeakyNun Yes, but you can do some tweaks such that it seems less imperative.

Erik the Outgolfer

なぜ彼らは日本語を知っているのに、なぜ人々はGoogle Translateを使いますか？

Leaky Nun

@Mr.Xcoder for example?

V. Courtois

2:24 PM

@mayube woot

Jim

Actually Pyth is also very functional oriented

V. Courtois

guguru turansureeto

Leaky Nun

@EriktheOutgolfer no, I don't use google translate

Erik the Outgolfer

not you specifically

Mr. Xcoder

@LeakyNun Look at your answer above. It doesn't really feel imperative.

Mayube

2:25 PM

先輩 is the only kanji I know

Leaky Nun

@Mr.Xcoder what?

@Mayube notice me

Mr. Xcoder

Although it is

V. Courtois

i use this coz i don't want to install IME on this pc

Mr. Xcoder

@LeakyNun It is so short that it leaves the impression that it's not imperative. But it is, of course

Leaky Nun

@Mr.Xcoder alright

Q: Turn a string inside out

A balanced string is a string of parentheses () so that every parenthesis is can be matched with another one. More rigorously they are the strings spanned by this grammar: S → (S)S | ε We can turn a string "inside out" by: Switching all occurrences of ( and ) with each other Moving characte...

Mr. Xcoder

2:46 PM

@dzaima Again your interpreter does not work for me.

dzaima

@Mr.Xcoder yeah.. I added support for many commands like time, wait and live output and that needed await

Really don't know what I could do

Mr. Xcoder

@dzaima Forget it, I trust you it's valid

Kritixi Lithos

@Mr.Xcoder what browser do you have?

Mr. Xcoder

Safari

dzaima

I guess I could host another version with await and async stripped

Mr. Xcoder

2:48 PM

That does not support async

@EinkornEnchanter Proof?

Einkorn Enchanter

@Mr.Xcoder Ok writing it up

dzaima

It wouldn't be that hard as I already have a compiler to which I could just copy-paste stuff

Mr. Xcoder

@dzaima To much hassle

Mayube

@LeakyNun I also know this Katakana メイブ :P

dzaima

@Mr.Xcoder Not that much

Leaky Nun

2:51 PM

@Mayube what is that?

Mayube

Leaky Nun

alright

dzaima

@Mr.Xcoder It'd be a one time only thing that I'd have to do

Mayube

which of course means my Discord username is now メイブ先輩

Einkorn Enchanter

@Mr.Xcoder Let us begin by saying that balanced subsections can be moved to the end without harm, that is if our string is xy we can make it into yx. This means that when rebalancing a string we can ignore subsections that are already balanced. Thus any string is equivalent to a string matched by )*(*, however since our initial string was balanced we know the number of open and close parens is the same. Thus we can just move all the close parens to the end of the string matching everything off.

I hope that makes sense

Mr. Xcoder

2:54 PM

@EinkornEnchanter Very strong proof, thanks!

Mayube

@EinkornEnchanter I miss WheatWizard :(
