Of course lol
 
@Mr.Xcoder what happened
 
Many things. Not really worth sharing
 
I can't even get sandbox question to work :)
 
If you're using the mobile app don't even bother to try

CMC: Given two arrays, determine if they have common suffixes or prefixes.
[1,2,3,4], [1,3,4,5] -> True (the prefix [1])
[2,3,4,5], [5,6,7,5] -> True (the suffix [5])
 
there it went
 
Basically check if their start / end is the same.
 
Jelly, 3 bytes: Ḣ€E (takes the two lists as one argument)
 
@cairdcoinheringaahing As a matter of fact, I have 75, not including two closed challenges without at least one downvote.
 
@DJMcMayhem How did you count them? :O - Have you ran a script to do it for you?
 
5:23 PM
is error checking my code a fun programming challenge?
 
No.
 
@Mr.Xcoder I manually counted >_>
 
how can I make it fun?
 
@DJMcMayhem ಠ__ಠ Old-school madness
@Webster Just don't ?
 
5:25 PM
Don't... Tell me... Have you manually created the Gist too?
 
What do you mean? I did manually create the gist by going to gist and pasting those in and hitting make public gist
 
ಠ_ಠ - I asked about the text of the Gist.
 
That's why I asked you to clarify
 
@Mr.Xcoder No excessive faces please.

Ok :c
 
5:26 PM
And yes, I made that manually >_>
 
Wow lol. Someone just upvoted all the answers to a challenge I hogged and I suddenly got +30
 
I have 15 bytes in Pyth for my older CMC: sm?/"aeiou"d.rdG (I think I can golf it)

Q: Jotto Optimization

WebsterJotto is a word guessing game similar to mastermind. Each person chooses a secret word and the other person tries to guess their secret word. The game is fun and I recommend you try it. This challenge is to come up with an optimum starting set of guessing words. Jotto Words: 5 letters each no ...

 
That ^ should not be closed as off-topic IMO, should be closed as a duplicate of sandbox.
 
It's not clear that they meant to sandbox it.

My favorite part about debugging C++ is digging through the pages of error messages from the STL to find the actual issue
 
But TBH, it doesn't really matter how it's closed as long as we explain that they can get help in the sandbox
 
5:35 PM
Yeah indeed C++ has very ambiguous error messages.
 
@Mego Painfully relatable. Like when you remove a semi-colon in a template class and get 73 errors.
 
There are three phases to understanding C++ errors: 1) I don't understand. 2) That message makes no sense, it should be ... 3) Ohhhhh. That's why it says that!
 
@DJMcMayhem or when you remove a semicolon anywhere, for that matter
 
also in C you make like one typo and it produces 5000 lines of compiler error
 
I once got 100 errors and 30 warnings for a double curly brace :-/
 
5:38 PM
@Mr.Xcoder yup, sounds like C++
 
@Mr.Xcoder -Wfatal-errors
 
I still don't understand why we have to use in school. And my informatics professor asked forced me to stop writing C code in C++ :-/
 
Anonymous
@DJMcMayhem I had exactly that problem. Putting in the semicolon (why didn't VS Code automatically insert it?!?) removed about 50 lines of errors.
 
Because VSCode is an editor (albeit an awesome one), not an IDE. Use CLion
 
@DJMcMayhem I feel very confident about mine now :P
 
5:40 PM
Huh?
 
@mınxomaτ I use CLion :-)
 
@DJMcMayhem Never mind
 
Also CLion sort of supports Rust debugging now, which is nice.
 
@Mr.Xcoder I had to learn PASCAL during the first 2 semesters in college. No idea why.
 
@J.Salle Lol we have to choose between Pascal and C++
(or C), but we have no professors that are into C unfortunately.
 
5:42 PM
We have to take Python. What a shame
 
Anonymous
@mınxomaτ VS Code with the C++ extension is an IDE, though it does some things oddly
 
Lol yeah, that's sad.
 
No offense Bjarne Stroustrup
 
Anonymous
@cairdcoinheringaahing Yeah, what a shame when you have to learn other langs and they're woefully inferior to Python
 
@cairdcoinheringaahing New students in my college have python instead of Pascal, which is also sad.
I wish I'd learned python lol
 
5:43 PM
@Mego I tried to get my CS teacher to let me do my controlled assessment in Jelly, but, given that he couldn't read it, he said no :(
 
@cairdcoinheringaahing Jelly has a built-in to interpret Python doesn't it?
 
@J.Salle ŒV yep
 
Can't you just pass the Python code as an argument and use it? Or does your school ban the standard loopholes?
 
I asked my teacher to let me solve something in Pyth instead and she accepted yay. But when they saw the code, they said that they've misunderstood, Pyth(on) instead.
 
@J.Salle I could do that, but that wouldn't be fun
 
5:46 PM
Wow. It seems like PPCGers asking their professors if they can use esolangs is more common than I would have though.
 
We heart Esolangs :-)
 
Anonymous
372 lines, 115,904 bytes, cause: templates
 
@DJMcMayhem Since joining PPCG I've used esolangs more than Python, so I know Jelly better than I know Python
 
@cairdcoinheringaahing yeah, I thought so
 
I am more confident with Pyth than Python too
 
5:48 PM
Put it this way, I've used almost all of Jelly's builtins at one point. I haven't come close to using all of Pythons
 
Have you ever used "primorial base"?
 
I assume you'd have to code for ages to use all of python's builtins
 
@Mr.Xcoder No, but I've never known a way I could use nonlocal in Python
 
Anonymous
@cairdcoinheringaahing nonlocal is really useful in decorators
 
Also, if you include all standard modules as part of Python, then no-one has ever used every single builtin
@Mego I only use @staticmethod and @property decorators. I've never really found a use for other ones
 
Anonymous
5:53 PM
I mean writing custom decorators
 
Anonymous
 
@Mego Yeah, I've never found any time where I've found writing custom decorators are easier than other methods
Also, what printable ASCII characters cannot be used outside of a string without causing a SyntaxError? I know of ?
 
oh wait nvm
 
> File ".code.tio", line 1
?
^
SyntaxError: invalid syntax
 
just about all of them tbh
 
6:04 PM
Hmm, $, ? and ` in Python 3
 
I almost said # and then I realized that this isn't Java... lol
 
@HyperNeutrino o_o # is the first character I went "Nope, that's ok"
 
@HyperNeutrino Both of those are valid characters
I'll see myself out

CMC: split a string into n equally sized chunks, the last chunk can be uneven
(...this will be one byte in neon)
 
@icrieverytim 1 byte in Levant, can't type it on keyboard though D:
 
oh hey how's Levant going? shorter than jelly yet? :P
 
Shorter than Jelly's source maybe :p
 
@icrieverytim Terribly. I lost the flash drive with the latest update on it D:
 
Oh still didn't find it?
 
6:12 PM
D:
 
2 bytes in Jelly D:
 
@Mr.Xcoder Nope. Been 3 days, I'm not confident
 
Isn't it just s in Jelly?
 
@HyperNeutrino No, that makes them all uneven, IIRC
 
it's œs
 
6:13 PM
oh
@cairdcoinheringaahing lies :c
unelss xcoder is wrong :P
 
@HyperNeutrino I was wrong
 
Yeah s splits them unevenly I think. I might be wrong though.
 
Actually æs is not valid either.
@icrieverytim test case please.
Yeah, it should be ≈ 4 bytes in jelly then
 
6:17 PM
Why doesn't œs work? @Mr.Xcoder
 
somebody else make test cases, I'm on mobile :P
 
Oh nevermind, æs does work.
 
I'm guessing but, "abcdefg", 3 => ["abc", "def", "g"]
 
sorry, the CMC is ambiguous, hence my confusion.
 
@Mr.Xcoder Wait, why does æs work? Isn't æ for arithmetic dyads?
 
"onetwothreefourfive", 3 -> ["one", "two", "thr", "eef", "our", "fiv", "e"]
 
@cairdcoinheringaahing Æ is for arithmetic stuff, æ is for "other dyads"
 
@Mr.Xcoder Isn't that œ?
 
I want to test the userscript: @caird your are on mobile right?
51 secs ago, by Mr. Xcoder
@cairdcoinheringaahing Æ is for arithmetic stuff, æ is for "other dyads"
 
@Mr.Xcoder No, not any more
 
6:21 PM
:o The cairdcoinheringaahing is typing thing is not working.
 
@J.Salle nah, that's splitting into n-sized chunks
 
@icrieverytim Yeah, I misunderstood the question
 
AE is monads, OE is dyads?
 
@icrieverytim come on, you can write a simple test case even on mobile.
 
I think I have it backwards
 
6:23 PM
> Æ atoms (arithmetic monads)
æ atoms (arithmetic dyads)
Πatoms (other monads)
œ atoms (other dyads)
 
@Mr.Xcoder ^^
 
@HyperNeutrino Æ means "arithmetic monads". Œ means other monads.
 
oh right it's uppercase monads and lowercase dyads :c
 
>_> fine
 
6:23 PM
And o/ and O/ are the nilads right?
 
huh?
 
like lowercase o-slashed and uppercase
wait no the lowercase has its own meaning I think
 
Oh yes Ø is nilads @HyperNeutrino
 
??? hm ok
 
@HyperNeutrino o-slashed isn't for nilads, its a nilad chain
 
6:24 PM
hm
 
6 mins ago, by caird coinheringaahing
I'm guessing but, "abcdefg", 3 => ["abc", "def", "g"]
 
(also we had to write out all our steps for science class but my teacher was fine with typing and printing it so I just wrote a program to write out the steps for me xD)
 
@cairdcoinheringaahing That's the same as J.Salle, and icry said it is incorrect.
 
@Mr.Xcoder No, mine splits into 3 chunks, which is what the CMC asked for
Or "abcdefg", 3 => ["ab", "cd", "efg"]
 
Ok, I will just refrain from answering the CMC
 
6:26 PM
@Mr.Xcoder Wait, there's a CMC going on? :P </joke>
 
@Mr.Xcoder I vaguely remember that
How did that work again?
 
@Sherlock9 No idea, sorry :c
 
@DJMcMayhem leading \0x00?
 
Not a problem. I'll look it up
 
6:29 PM
@H.PWiz (shhhhh)
 
Also, what is the point of primordial base?
 
Oh wait a second
I'm splitting into lists of length n, not n lists
shit
 
yeah like 10 people got confused by that xD
wait can't you just do sZ?
 
@cairdcoinheringaahing Well first off you should not typo it. it is "primorial", not "primordial".
 
Dang it, I thought Hey I could do this in V! before realizing I understood it wrong, so I thought Oh well, I could just do it in brain-flak instead, and then I still did it wrong >_>
 
6:31 PM
@EriktheOutgolfer Want to try to solve this as well
Should be going to sleep though
Class in six hours, first alarm goes off in four
 
Yeah, you should really go sleep :P
 
Aww, shh, I have to sleep in ~ 1 h too
@cairdcoinheringaahing Your latest challenge is nice, but parenthesis kill the fun D:
 
@Sherlock9 great
 
@Mr.Xcoder Happy‌​?
 
rip (' instead of ") (also "primordial" "jelly" doesn't have any results too)
 
6:34 PM
Yes.
 
if only recursive regex worked :c
 
@Mr.Xcoder Hmm. While writing it, I thought it would be too easy without parenthesis, so added it in on a spur of the moment.
 
my idea is to just find all bracketed expressions and eval them
 
@HyperNeutrino Doesn't Retina have that?
 
yeah but then it's weird for the rest of it
 
6:36 PM
Now I remember what I thought I meant by "primorial base": I was thinking of the Residue Number System
 
I'm interested to see if an answer that handles parenthesis could be ported to an answer that doesn't. If it can't be, then I could make an easier form of the challenge.
 
probably just delete the part handling parentheses
 
in Jelly, 1 min ago, by Mr. Xcoder
@Dennis What is the point of Æ? (primorial base) in Jelly? Has it ever beed used when golfing?
 
Goddamn it. Why can't we edit questions when they're deleted?
CMQ: Should I remove the parenthesis part from my question? Keep in mind that it seems as though mbomb is working on an answer
 
6:39 PM
no
it's too easy otherwise xD
 
Also I do like the "Is there really any purpose of adding parentheses to the challenge? It makes it more difficult. Aside from that, not really." comment exchange
 
Well we could technically use eval but (some) golfing languages do not support it online because of -s
Does mbomb only solve hard challenges?
 
@Mr.Xcoder I don't know, but if he does, it seems better than getting rep from FGITW'ing challenges glares at Leaky
 
glares at Leaky -- Leaky stopped doing that; getting rep from FGITW'ing challenges -- glares at myself
CMC: Given an array A, return the shortest subarray (M) of A (not necessarily contiguous) such that the sum of M is at least half of A's sum.
 
What do you mean by subarray (not necessarily contiguous)?
Does that mean any partition of the array?
 
6:52 PM
@Mr.Xcoder VTC as dupe of JHT challenge
 
@cairdcoinheringaahing Huh?
 
@cairdcoinheringaahing you can't actually do that
 
@DJMcMayhem I meant subset, but a set cannot contain duplicates, so I avoided it :-/
 
jht challenges tend to be a bit different
 
@Mr.Xcoder Wait, so can we use duplicates in this challenge?
 
6:53 PM
Test case?
 
@DJMcMayhem Yes. Let me write down an example for "subarrays"
The sub-arrays of [1,2,3,4] are the following: [[], [1], [2], [3], [4], [1, 2], [1, 3], [1, 4], [2, 3], [2, 4], [3, 4], [1, 2, 3], [1, 2, 4], [1, 3, 4], [2, 3, 4], [1, 2, 3, 4]].
 
OK, so any partitions
 
So powerset
Jelly, 14 bytes: ŒPµ³SH>SµÐḟL€Ṃ
 
@DJMcMayhem Yes.

@EriktheOutgolfer Huh? What's unflagging?
 
the h bar is generating a lot of flags lately

@EriktheOutgolfer I said the same thing in JHT yesterday
 
@cairdcoinheringaahing informal way to say "flag voted on as 'not valid' by enough people"

@Mego Eh. Not really nice. It's outdated, slow to respond to commits, pricey (for serious work) and most importantly has no way to actually display test results in any meaningful way. Compared to e.g. VSTS Test results from it's CI pipeline, Travis is a toy. And that's saying something, because I have a deep hate for VSTS.
