opening tabs

Tabs opened :P

Mr. Xcoder

Ok, I think I have a CMC in mind.

caird coinheringaahing

@Mr.Xcoder Good, because I can't think of one, and when I can't think of one, I think of insanely difficult ones :P

Mr. Xcoder

CMC: Given a list of positive integers, return those that are closest to another given integer. (if more are closest, you must output them all)

[3, 4, 5, 7, 7, 8, 7], 6 -> [5, 7, 7, 7]

@cairdcoinheringaahing

caird coinheringaahing

@Mr.Xcoder Yeah, I'm here. Just annoyed that Jelly doesn't have an inverse version of M

Mr. Xcoder

15:04

Why'd you need M anyway?

caird coinheringaahing

> Return all indices of z that correspond to maximal elements.

Mr. Xcoder

Ik

3 bytes here.

caird coinheringaahing

ಠ_ಠ I'm overthinking this, aren't I?

Mr. Xcoder

Yes, you probably are (lol come on)

caird coinheringaahing

Ok, I have 9 bytes

ạµṀ_µMµị³

Mr. Xcoder

15:06

<---- is very dumb ಠ_ಠ. I fixed mine, and it's still 3 bytes now.

Too many µs :o

@cairdcoinheringaahing Hint Explore the quicks. (another hint: I (ab)used it to outgolf Dennis (barely))

caird coinheringaahing

@Mr.Xcoder 3 bytes

Mr. Xcoder

Nice

Mine is that too. BTW The thing I fixed is _ -> abs diff (earlier)

@cairdcoinheringaahing Should I think of another CMC or leave it to you? :P

caird coinheringaahing

I see you had another FGITW challenge :P

@Mr.Xcoder I'll try to think of one

Mr. Xcoder

@cairdcoinheringaahing Actually I had 2 FGITWs and then 4 consecutive crazy Slowest-gun-in-the-west (posted those after ~12 hours)

caird coinheringaahing

@Mr.Xcoder Link?

Mr. Xcoder

15:11

@cairdcoinheringaahing Link to Dennis being barely outgolfed

?

caird coinheringaahing

@Mr.Xcoder Yeah. I can't find it

Mr. Xcoder

Here you go:

45

Q: Coprimes up to N

Given a number n >= 2, output all the positive integers less than n where gcd(n, k) == 1 (with k being any one of the output numbers). Numbers of this sort are coprime to each other. Example: 10 gives the output [1, 3, 7, 9] (in any form you like, as long as the numbers are unambiguously separa...

Lol, all my badge counts are repdigits: 3, 33, 111 :O

caird coinheringaahing

CMC: Given a multiplication problem, convert it into the shortest series of additions possible using a number from the original problem. Example: 5 * 2 = 5 + 5 and 9 * 7 = 9 + 9 + 9 + 9 + 9 + 9 + 9

Mr. Xcoder

brb

@cairdcoinheringaahing nice +1

caird coinheringaahing

@Mr.Xcoder I'm planning on making a main challenge that is sort of a superset to that

Mr. Xcoder

15:17

@cairdcoinheringaahing Leaky outgolfed 3 bytes :O

nvm

caird coinheringaahing

@Mr.Xcoder Yeah, I don't think it's possible to outgolf 3 bytes for that CMC

@cairdcoinheringaahing Input may be taken as a list (5 * 2 => [5, 2])

Mr. Xcoder

@cairdcoinheringaahing We cannot assume they are sorted, right?

caird coinheringaahing

@Mr.Xcoder No, sorry

Mr. Xcoder

ಠ_ಠ Jelly made me copy-paste the character j

caird coinheringaahing

in The Nineteenth Byte, Sep 26 at 20:26, by caird coinheringaahing

ಠ_ಠ I hate what Jelly has made me do. I just copy pasted the character W

Mr. Xcoder

15:22

:o

caird coinheringaahing

Its a common problem :P

Mr. Xcoder

Did you know that µ can be written from the mac keyboard

caird coinheringaahing

Ok, I have 6 bytes for my CMC

@Mr.Xcoder Yeah, but I'm on windows at the moment

Mr. Xcoder

brb chat flags

caird coinheringaahing

@Mr.Xcoder #10krepproblems :P

Mr. Xcoder

15:24

The h Bar has tons of flags lately

(Physics chat room)

caird coinheringaahing

@Mr.Xcoder Do I want to know why it's called The H Bar?

Mr. Xcoder

@cairdcoinheringaahing Nope you don't

@cairdcoinheringaahing can we output as 9+9+9+9+9+9+9 instead?

caird coinheringaahing

@Mr.Xcoder Yeah. That's what mine does

Mr. Xcoder

ṀxṂj”+

caird coinheringaahing

@Mr.Xcoder Same here :P

Mr. Xcoder

15:29

CMC: Given a list, repeat each element a number of times equal to each element in the list. Hard to explain, so:

[9, 7, 3] -> [[[9, 9, 9, 9, 9, 9, 9, 9, 9], [7, 7, 7, 7, 7, 7, 7, 7, 7], [3, 3, 3, 3, 3, 3, 3, 3, 3]], [[9, 9, 9, 9, 9, 9, 9], [7, 7, 7, 7, 7, 7, 7], [3, 3, 3, 3, 3, 3, 3]], [[9, 9, 9], [7, 7, 7], [3, 3, 3]]]

What do you think?

caird coinheringaahing

@Mr.Xcoder Looks easy, but isn't as easy as it looks :P

Mr. Xcoder

ok... EDIT I am done, I will not reveal the byte count yet.

caird coinheringaahing

@Mr.Xcoder ಠ_ಠ Its easy isn't it?

Mr. Xcoder

@cairdcoinheringaahing Not really obvious.

The Pyth equivalent would be hell much longer

caird coinheringaahing

@Mr.Xcoder Does it have to be in that order?

Mr. Xcoder

15:32

@cairdcoinheringaahing What order do you suggest?

caird coinheringaahing

@Mr.Xcoder

[[[9, 9, 9, 9, 9, 9, 9, 9, 9], [9, 9, 9, 9, 9, 9, 9], [9, 9, 9]], [[7, 7, 7, 7, 7, 7, 7, 7, 7], [7, 7, 7, 7, 7, 7, 7], [7, 7, 7]], [[3, 3, 3, 3, 3, 3, 3, 3, 3], [3, 3, 3, 3, 3, 3, 3], [3, 3, 3]]]

Mr. Xcoder

Actually, it should be exactly in that order.

@cairdcoinheringaahing From that point, you can just transpose lol

caird coinheringaahing

ಠ_ಠ I have 4 bytes if I have to output in that order. 2 bytes otherwise

Mr. Xcoder

2 bytes ordered.

Can I see both?

caird coinheringaahing

2 bytes: ẋ€ . 4 bytes: ẋ€µZ

Mr. Xcoder

15:35

Pyth, 7 bytes (mine, if that helps any): mm*]kdQ

caird coinheringaahing

@Mr.Xcoder :/ I don't know Pyth. That looks like Jelly before I learnt it :P

Mr. Xcoder

@cairdcoinheringaahing Should I reveal mine or wait?

caird coinheringaahing

@Mr.Xcoder Go ahead and reveal.

Mr. Xcoder

xþ

caird coinheringaahing

Ugh, outer product. Well, it has it uses

Mr. Xcoder

15:37

Now I want a proper, non-built-in, harder CMC

Oh wait.

I have a challenge idea for main... Yay posting! You can post a CMC if you want, I am still available :D

caird coinheringaahing

@Mr.Xcoder I think I'll have a go at your challenge :P

Mr. Xcoder

@cairdcoinheringaahing It will take some time to write it.

caird coinheringaahing

Can you ping me when it's posted?

Mr. Xcoder

Sure.

And it's not too hard, but not too trivial either

ಠ_ಠ Now I have to make a program for the test cases... Lazy.. bah

caird coinheringaahing

CMC: Given an array of numbers, find the mean of the mean, median and mode of the list. Example: [1, 2, 1, 3, 1, 2, 3] => [1, 1.8571428571428572, 2] => 1.6190476190476193

I have 9 bytes

Mr. Xcoder

15:44

10 atm

Æṁ+Æṃ+Æm÷3 will golf

caird coinheringaahing

Mine isn't too obvious until you get it :P

Mr. Xcoder

Well does it use the new quicks, like tie or key or smth (dunno what those do yet)

?

caird coinheringaahing

@Mr.Xcoder No. Tie is alternate between the previous n-links, and I have no idea what key does

Mr. Xcoder

@cairdcoinheringaahing What is the notation for list literals? [a,b,c] or abc] or what?

caird coinheringaahing

@Mr.Xcoder [<nilad>,<nilad>] etc.

Mr. Xcoder

15:48

nilad? Bleh

caird coinheringaahing

Hmm, it's 6 bytes in Levant. \o/

Mr. Xcoder

ಠ_ಠ I can't wait to use it too

caird coinheringaahing

@Mr.Xcoder Well, it'll be a while :( I lost the memory stick with my code on it

Mr. Xcoder

What is the 9-byter?

caird coinheringaahing

@Mr.Xcoder You want me to spoil?

Mr. Xcoder

15:51

@cairdcoinheringaahing ಠ__________ಠ Why would you use a memory stick

@cairdcoinheringaahing whatever, post it

caird coinheringaahing

@Mr.Xcoder More than one computer

Mr. Xcoder

@cairdcoinheringaahing Isn't that what GitHub is for?!

caird coinheringaahing

@Mr.Xcoder Æṁ;Æṃ;Æm⁺

@Mr.Xcoder Can't run Python from GitHub

Mr. Xcoder

ಠ__ಠ How did I not see the 9 byter

caird coinheringaahing

Actually, I'm going to go look for my memory stick (among other things). Should I ping you when I get back?

Mr. Xcoder

15:54

sure, I am quite busy too rn

Mr. Xcoder

16:30

@cairdcoinheringaahing Posted.

caird coinheringaahing

16:50

@Mr.Xcoder Nice. Presumably, you've made it in Jelly?

Mr. Xcoder

Nope in Pyth

caird coinheringaahing

Aaand, there's the Jelly answer :P

Mr. Xcoder

@cairdcoinheringaahing actually 2. Leaky outgolfed erik by 7 bytes

caird coinheringaahing

@Mr.Xcoder Yeah, just saw. Says something doesn't it? :P

Mr. Xcoder

Gtg homework
