eulerscheZahl: staff's answer to another complain about vim:
What is used is https://github.com/brijeshb42/monaco-vim, feel free to create an issue on their github!
_-: Thanks. I will report it.
shangcode: Please, someone, tell me, if I can write the funny puzzles which in the clash to my blog?
I wonder if there is some clause to forbidden this.
Allis: https://www.codingame.com/playgrounds/40701/contribute---help/licensing
shangcode: Thanks a lot!
Allis: Sure thing.
PoojaUmashankhar: can i view the previous coc I answered?
jrke: goto noftification click on clash result you will be redirected to clash result page
eulerscheZahl: http://eulerschezahl.herokuapp.com/codingame/puzzles/
to search for the clash and try it again without time pressure
Allis: Very cool.
shangcode: Cool

Illedan: eulerscheZahl that search text box is hard to see :D
eulerscheZahl: complain to the user who gave me the CSS :P
Illedan: Where is he :eyes:
eulerscheZahl: i even forgot who he is
AntiSquid: #category {
height: 300px;
width: 600px;
}
AntiSquid: something like that
AntiSquid: i didn't give you that css though
eulerscheZahl: not you
eulerscheZahl: someone with lots on unicode characters in the nickname on discord
eulerscheZahl: i can't even read it. who does this?!
AntiSquid: can't read the css file?
eulerscheZahl: the discord nickname
AntiSquid: ah lol
AntiSquid: is it to put them at the top?
AntiSquid: in the user list
eulerscheZahl: https://prnt.sc/tuwq1k
that's the one who gave me the stylesheet
AntiSquid: ah from different discord channel eh?
AntiSquid: can't you edit your CSS ?
eulerscheZahl: CG discord. And i can edit it of course. i just don't care enough
AntiSquid: i gave you an example above how to select by ID
LinhT.Nguyen: hehehehehehehheheheheh
AntiSquid: LinhT.Nguyen how is it going what's with the hehes ?
eulerscheZahl: give me a full CSS or i won't even bother opening my editor :D
LinhT.Nguyen: spamming obviously heheheh
eulerscheZahl: have to press windows+A to open Atom. So much work
AntiSquid: forgot where to download the css file ... to lazy to find all the classes and ids
AntiSquid: too *
AntiSquid: LinhT.Nguyen no spamming, Automaton2000 will get angry
Automaton2000: no, i was just thinking that
PatrickMcGinnisII: omg, quest map got me a new lvl, but damn
PatrickMcGinnisII: decided to improve Code of the Rings, got the quest xp... but then realized why i stopped doing it in the first place
PatrickMcGinnisII: It's like doing a defrag for a predetermined superfetch...yuck
PatrickMcGinnisII: Brainf*ck, no kidding
PatrickMcGinnisII: [[<]>.] Automaton2000 it's your borther
Automaton2000: and you are on the same cell?
FinnWerner: i have problems with a debug
Tiramon: general advice .. if you have problems and hope for help ... tell us what your problem is and not only that you have a problem
eulerscheZahl: switch your avatar to 1.FCN and I might help you FinnWerner :P
Tiramon: and i thought i was the one working in dortmund ;)
Tiramon: and should have a problem with schalke
eulerscheZahl: i'm just nagging, I don't have anything against Schalke
Tiramon: me neither
Tiramon: i don't care for football
eulerscheZahl: i play myself. that's more fun than watching others play
FinnWerner: Schalke und der Fcn:grin:
FinnWerner: and thanks i have fixed the problem
Dame_Mas_Onii-chan: https://www.codingame.com/clashofcode/clash/132612673ff016fda3cc495efef31c5b5af08b4
Tiramon: Dame_Mas_Onii-chan plz no clash invites in this channel
eulerscheZahl: AntiSquid already kicked him yesterday for this
eulerscheZahl: go to #clash for those links
Dame_Mas_Onii-chan: ok
Andriamanitra: i don't understand how three people thought merging partially overlapping strings is a good clash problem
Andriamanitra: takes average programmer more like an hour than 5-10 minutes lol
JBM: elitist bunch
eulerscheZahl: https://www.codingame.com/contribute/view/50633c3cbd3a763444ff46065cdeb90b02cc
this one?
eulerscheZahl: "Good idea,
not too easy, not too hard"
Andriamanitra: yup that's the one
aquire: I see lot of skilled people use Ruby, especially for code golf. Is it worthwhile to learn it? I started doing path_to_elightenment.rb. Please tell your opinions.
JBM: it's worthwhile to learn most any language
Andriamanitra: depends on what your goals are
Uljahn: ^
Andriamanitra: i use ruby because it's fun and has an absolute ton of stuff already built in
aquire: My goal is to become #1 on CoC
JBM: you must know ruby
JBM: and perl and bash
Andriamanitra: yeah in that case you probably need ruby for golf :grinning:
aquire: I'm originally a pythoner
JBM: too bad
aquire: Did python all my life
aquire: Yeah
JBM: yeah i don't know if *you*'re worth it
eulerscheZahl: and just should know most of the clashes by heart
JBM: but you can try
aquire: > and just should know most of the clashes by heart
wdym?
JBM: you won't get to #1 by playing each clash just once
aquire: Oh that's the secre?t
JBM: one of them
aquire: Then it's too boring
JBM: it is
JBM: but hey, you picked the goal
aquire: Yes Didn't know that
aquire: Anyway I'll learn ruby
aquire: seems interesting
JBM: never a bad idea
Andriamanitra: it might not be the most useful language for general programming these days but it never hurts to know more
JBM: ruby is general-purpose enough
Andriamanitra: yeah but if you already know python there is rarely a reason to use ruby instead, they fit many of the same use cases well
aquire: Python swallowed most scripting languages, lol
aquire: along with js
elderlybeginner: how to simplify it in python:
not (A and B or C and D)
DomiKo: hi ;)
jacek: good afternoon
aquire: A,B,C,D are booleans?
amammamamam: pls join
jacek: well duh
eulerscheZahl: A and B => A*B
amammamamam: my clash
eulerscheZahl: no amammamamam
elderlybeginner: a,b,c,d booleans, yes
aquire: there's not imply operator in python ifaik
eulerscheZahl: use math elderlybeginner
A and B => A*B
eulerscheZahl: with => I mean replace it
eulerscheZahl: not(A*B+C*D)
aquire: ah ok
elderlybeginner: "A and B => A*B" - no, * has higher precedence then and
eulerscheZahl: i don't get what you are saying
aquire: nice!
elderlybeginner: A, B, C, D are tests, I will have to take it in ()
eulerscheZahl: and the not part can be shortened further:
A*B+C*D<1
aquire: yep
eulerscheZahl: you only get a good answer if you ask the right question. how should we know that A and B are not just variables?
aquire: pretty neat
elderlybeginner: @eulerscheZahl: thank you
elderlybeginner: it regards to that:
['R' in d and z
p]
eulerscheZahl: don't panic?
Astrobytes: looks like it
eulerscheZahl: i had the feeling for the last couple minutes
elderlybeginner: and switched 1 with 0; yes, of course don't panic :)
eulerscheZahl: 'L' in d
d<'M'
elderlybeginner: nice :)
dbdr: global pandemic, eulerscheZahl doing golf; 2020 is a weird year indeed
JayBeAl: hey guys
elderlybeginner: is pythonic replacement of A and B or C and D with any()/all()
JayBeAl: i´ve just ranked up to gold in coders strike back. Is 'angle' in gold the same like 'nextCheckpointAngle' in silver?
Memo12334: guys im stuck
Memo12334: in codingame
Maxlaxs: You are missing the most important part: Stuck with what?
Memo12334: rock paper scissors lizard spock
Memo12334: idk why my code prints a specific thing , oh I am joining the discord
Andriamanitra: @elderlybeginner when you only have two conditions using any() doesn't make much sense, i think just writing "A and B or C and D" is more readable
LeBaoHoang8A4: Hello, how to print all the moves of all pacs in wood1? I tried what they said but it didn't work.
jrke: do it like command for pac 1|command for pac 2| and so on.......
jrke: like if you have 2 pacs then
JayBeAl: i´ve just ranked up to gold in coders strike back. Is 'angle' in gold the same like 'nextCheckpointAngle' in silver?
jrke: MOVE pac_1_id target_x target_y|MOVE pac_2_id target_x target_y
LeBaoHoang8A4: thanks
jrke: nope its absolute angle in gold of csb
JayBeAl: meh but why did it change?
LeBaoHoang8A4: and we need to find the shortest rout, right?
LOMLOM: hi, anyone knows why sometimes float to int cast turns 54.0 to 53 or 90.0 to 89?
Andriamanitra: floats are approximate, 54.0 might actually be 53.9999999999998 or something and casting to int usually rounds down
jrke: yeah and int round downs the no
Andriamanitra: most languages have rounding function that you can use
LOMLOM: ye even if i use round() i get wrong values
LOMLOM: floor() *
jrke: I think all lang has round func
Andriamanitra: well yeah floor rounds down
LOMLOM: but the value is exactly 54.0
LeBaoHoang8A4: minus by 1?
Andriamanitra: there is no such thing as exact float my friend, it's an illusion that will bite you in the ass sooner or later
LOMLOM: im using c++
jrke: lemme then if c++
jrke: its working
jrke: cerr<<int(54.0)<<endl;
jrke: gave me 54
LOMLOM: its not always the case for me
jrke: thi gave 53 cerr<<int(53.99)<<endl;
jrke: this*
Galaxy_001: https://www.geeksforgeeks.org/round-in-cpp/
jrke: maybe its not exact 54.0
SPDene: where are you getting the value from? it's probably 53.99999999999
LOMLOM: when i print the value as a float i get 54
Andriamanitra: never trust floats
jrke: and always trust toads ;)
LOMLOM: toads ??
SPDene: even hypnotoads?
Galaxy_001: no doubles
Andriamanitra: even a+b == b+a is not always true when using floating point arithmetic :wink:
jrke: does rand() in cpp also gives negatives?
Andriamanitra: no
SPDene: "Returns a pseudo-random integral number in the range between 0 and RAND_MAX." - so no, not unless you do something else with the value
LOMLOM: this is so wierd
jrke: can i do like rand()%-100 to get negatives
Astrobytes: Try std::uniform_real_distribution
Galaxy_001: not abs()
Galaxy_001: abs() gives positive values
SPDene: absolutely :)
Galaxy_001: abs:joy:
jrke: :)
SPDene: hey, my jokes might be bad, but at least here, I have confidence that people know WHY they're bad :)
Andriamanitra: someone share the code for this ridiculous polygon problem please
Andriamanitra: i'm sure i couldn't get it done even if i was given all day
eulerscheZahl: the polygon problem
i think we all instantly know which one that is, don't we?
eulerscheZahl: (sarcasm)
Maxlaxs: Think he was talking to the coc team
Andriamanitra: ^ yeah sorry
Andriamanitra: i dont know if there's a way to see the problem after submitting i cant remember what it was called any more
eulerscheZahl: http://eulerschezahl.herokuapp.com/codingame/puzzles/?q=polygon&category=CLASHOFCODE
is it here?
Andriamanitra: yeah it's the area of polygon
Andriamanitra: that's an useful site huh
eulerscheZahl: sounds like a google question
eulerscheZahl: https://www.mathopenref.com/coordpolygonarea.html
Andriamanitra: i did basically that (after googling lol) but it only works for convex polygons i think
Andriamanitra: which is why i only got 25%
eulerscheZahl: did others score 100%?
Andriamanitra: 2 people out of 8 did
jrke: euler nice website
eulerscheZahl: thanks jrke :)
Andriamanitra: hmm, that does claim it works for concave polygons too, i wonder what i did wrong then
jrke: what you used to make it euler js/html/php or any other thing
eulerscheZahl: python (Django)
eulerscheZahl: with free hosting on heroku
jrke: ok
eulerscheZahl: backend looks horrible :D
eulerscheZahl: puzzle DB has 3 columns: link to the contribution, puzzle, comments
eulerscheZahl: the puzzle is a json, so each time you search, i deserialize it and check for the keywords in the json object (the statement, testcases, ...)
eulerscheZahl: and give different score depending on where I find it (title is more relevant than body or comments)
Allis: Hm... it doesn't seem to handle numbers well?
eulerscheZahl: could you give an example? just tested "123"
Allis: There's a really annoying puzzle that seems to be reverse-only where you need to figure out how to get from 583 to 440.
Allis: I searched those numbers to confirm/deny the reverse-only hypothesis, but it was all false positives.
eulerscheZahl: and a rather long list
aquire: nice website euler
aquire: is it opensource
aquire: I'd like to see it
eulerscheZahl: https://www.codingame.com/contribute/view/143765bb4be8ad4a3b98b684ddbd0ed971e9
eulerscheZahl: this seems to be it Allison
eulerscheZahl: srong ping :/
eulerscheZahl: wrong*
eulerscheZahl: not open source aquire
i'm ashamed of my own mess
aquire: ok no problemo
aquire: don't be lol
aquire: I like mess actually
aquire: (In a positive sense)
eulerscheZahl: doing a cleanup (aka full rewrite) is on my list for a while
Allis: That's definitely the one, thanks.
Allis: I guess it makes sense to not show all the test cases in your interface.
eulerscheZahl: i do it that way because it's easier actually :P
eulerscheZahl: CG has an API that gives the puzzles in a formatted way
eulerscheZahl: one field is testcases/validators
Allis: Right, makes sense.
eulerscheZahl: another one is the statement as HTML
eulerscheZahl: so all i do is print the html formatted statement and the testcases are just not part of it
aquire: have you guys seen this!https://www.youtube.com/watch?v=BxV14h0kFs0

Q12: http://chat.codingame.com/pastebin/45e04d64-a588-4207-9fc3-46501230bf65
Q12: Hi, I'm trying to solve the game Guessing n Cheating and I passed all the tests but when I got to the Validators I was able to pass them all except Validator 2. I tried for over half an hour already to find the problem but failed. Can someone look at my code and tell me why it does not work, please?
(UP)
Maxlaxs: You shouldn't paste full code :/
eulerscheZahl: you could use my website too Q12
eulerscheZahl: locate the puzzle, open the demo IDE and play the validator
eulerscheZahl: Found: No evidence of cheating
Expected: Alice cheated in round 3
Q12: What the url of your website?
Q12: *is
eulerscheZahl: http://eulerschezahl.herokuapp.com/codingame/puzzles/?q=guessing&category=ANY
Q12: Thanks a lot :grinning:
Q12: I really appreciate :slight_smile:
Andriamanitra: chat shouldn't steal focus when clash begins T_T
Andriamanitra: it costs a precious second every time
eulerscheZahl: add ?disableChat to the URL
Andriamanitra: i like seeing chat i just don't like it taking focus
_-: hey Ruby people it's not fair!
Andriamanitra: i agree! it's completely unfair that you only need 5 characters to convert string to int in python while it takes 6 in ruby
_-: Ah lol
Andriamanitra: oh wait actually .to_i is only 5 characters, it just looks longer than int()
Andriamanitra: at least you have map(int,x) i guess :grinning:
GInnjo: What in the hell? I just submitted my result that failed one step but got 100% and gave me that same which failed to be successful
Allis: You got lucky and your implementation worked on all the validators (hidden test cases).
Allis: Python's biggest golf win over Ruby is `[::-2]`.
GInnjo: I know it was something about search speed from table. Dunno what could have been faster than hashtable based on string length and first letter. Still timed out, making me not to press "submit" button. :/
cjzw: someone check out my latest contribution
Astrobytes: You don't need to keep asking people to check it out every day cjzw. It's in Contributions, people will check it out. Have patience.
_-: That's a winning mentality right here Andriamanintra
_-: Wait for me to finish path_to_enlightenment.rb. I'll finish y'all
Allis: Are you enjoying the Koans?
Qwerty_1331: hey guys
_-: yes
_-: still on objects
_-: problem with object_ids
_-: How can I paste things here?
_-: I saw someone use a kinda pastebin
Allis: I think it auto-pastebins long messages?
_-: ah ok
_-: I have a problem with this
_-: http://chat.codingame.com/pastebin/e66db934-b0e9-4e8e-acab-fe6ed9c26b88
Allis: You don't expect #clone to create a new object?
_-: It says small numbers have fixed ids. So if I do something like
_-: obj=1
_-: copy=obj.clone
_-: then this is a contradiction right?
_-: (To what I pasted )
Allis: It is, and you just kinda have to be aware of the fact that small-enough integers are secretly just tagged pointers under the hood.
Allis: They're a special case that the Koans don't really bother to go over.
_-: Ok thanks
Allis: Sure thing. Be advised that Symbols also contradict the rule.
_-: And to your earlier question, python behaves the same way so I expected that more or less
Allis: That's good.
_-: I'll gloss over this anyway. Don't think I'll need the under the hood stuff
_-: Right?
Allis: Not unless you catch a mood and decide to get your hands dirty.
Allis: p ObjectSpace.each_object.select { |o|
o.__id__ == o.clone.__id__ rescue nil
}
Allis: You can run that to see which objects that exist when you start the interpreter don't actually make a new object when cloned.
Allis: it's all Symbols, Integers, and—on my machine—a Float and a Complex.
Allis: Yes, Ruby lets you just iterate over every single living Object if that tickles your fancy. :sweat_smile:
_-: python has it too __globals__ and __locals__ I think
_-: rather globals() and locals(). I wonder we both are talking about the same thing tho
_-: By Symbols you meant things starting with : I suppose
_-: http://chat.codingame.com/pastebin/41523e67-cc32-42e6-ad1a-95803021f9f3
Allis: Yeah, those are Symbols; they're effectively "efficient strings", and are generally used accordingly.
Allis: They're immutable (unless you get your hands dirty with something like Fiddle, but ignore that) and references to a particular Symbol always refer to the same object in memory; great for things like Hash keys, method names, things of that nature.
_-: Nice. I'm now in about_hashes.rb. Now I know why hash keys are Symbols
_-: Makes sense
SneakyDoodle: Man python3 is popular on this site.

MaliciouslyCrypticUsername: I was forgetting to clear my lists of humans every turn lol
eulerscheZahl: you have dead code
eulerscheZahl: ba dum ts
MaliciouslyCrypticUsername: ???
eulerscheZahl: zombies, dead code...
a joke isn't fun when you have to explain it
MaliciouslyCrypticUsername: Oh
MaliciouslyCrypticUsername: I see
MaliciouslyCrypticUsername: Ha ha ha?
eulerscheZahl: thanks for being polite about that nonsense :D
MaliciouslyCrypticUsername: You're welcome?
MaliciouslyCrypticUsername: I keep failing on split second reflex
MaliciouslyCrypticUsername: Going for the closer zombie every time
Astrobytes: You're being outgunned in the humour stakes by a German MaliciouslyCrypticUsername. Must try harder :D
eulerscheZahl: thanks for breaking the awkward silence
mingmingrr: got a zombie problem? try picking your brain for ideas
MaliciouslyCrypticUsername: ...
MaliciouslyCrypticUsername: ...
eulerscheZahl: so..
you don't save the humans in some testcases?
dbdr: https://www.youtube.com/watch?v=FBWr1KtnRcI
MaliciouslyCrypticUsername: In that one testcase specifically. My code makes ash move towards the closest human, but in this case the closest human is a turn away from getting eaten
Astrobytes: lol dbdr
BeardedBrocolli_4577: anybody? im stuck with the validator phase
BeardedBrocolli_4577: in the murder in the village puzzle
BeardedBrocolli_4577: Im not supposed to know whats that to avoid hardcoding I get it
BeardedBrocolli_4577: but also no idea whats wrong
BeardedBrocolli_4577: failed 1 of 6
JBM: you solve all tests but 1/6 validators?
BeardedBrocolli_4577: yeah LOL
BeardedBrocolli_4577: wait nvm im gonna try somethin
JBM: sounds like a bad puzzle then
BeardedBrocolli_4577: nah its my fault I see the wrong now
Juunas: hi
jacek: ohai
Qwerty_1331: eyo
MSmits: hi
Meowsuke: hiii
mateusedival: hi
jacek: c-c-c-combo breaker
MSmits: wha?
MSmits: is that from killer instinct?
Putnam3145: yes
MSmits: N64?
Putnam3145: i was about to call it old-school but--okay nevermind it is
jacek: :nerd:
OddBitKid: after every Clash of Code session we asked about test case relevancy. What exactly does it mean?
MSmits: it means do the test case test the problem well
Putnam3145: i've been basing it on whether the test cases properly test edge cases
Putnam3145: and, also, like
Putnam3145: if I 100% the test cases with a non-hardcoded solution but don't get a 100% on scoring, I guess?
Putnam3145: but that's never actually happened
Putnam3145: (i don't do hardcoded solutions)
Putnam3145: (who even has TIME for that)
OddBitKid: Hmm
Astrobytes: Sometimes only the validators test the edge cases
MSmits: which is undesirable
Astrobytes: Think it's less the case with newer ones
Astrobytes: hi MSmits btw
OddBitKid: I assumed that it was on the relevancy for the challenge for testing programmers skill
MSmits: hi Astrobytes
Astrobytes: It's about how relevant the test cases are to the problem being solved
OddBitKid: I assummed that test case covery was easily tested by the engine and som simple stats
OddBitKid: maybe they should put at tiny explainer to the ratings - I might not bee the only one to get i wrong initally
Astrobytes: Coc's are user-created, sometimes users don't have the best test cases (or indeed validators)
Astrobytes: I guess it was supposed to be meaningful in that regard
OddBitKid: Thanks
OddBitKid: I got it.
Putnam3145: i think the rating criteria are good
Putnam3145: occasionally I get a CoC whose *entire* difficulty is ignoring all the chaff in the word problem
Putnam3145: like, to the point that I feel it was written specifically to confuse the reader
Putnam3145: but there's a rating criterion for that
Astrobytes: I'm guessing some things are perhaps gonna change a little with the recent updates and whatnot, but rating systems are always affected by subjective bias I guess
MSmits: yeah i hate that kind of description
Putnam3145: hmm
Putnam3145: why do I want to write everything in a functional way these days
MSmits: cuz that's so you
JBM: cuz that's how it should be
tssw: ups
Astrobytes: cuz (reduced)
Putnam3145: trying code of the rings and deciding to program in a completely different way than i normally do
Putnam3145: to be exact i'm constantly thinking of, like, whether I can make my code look less "special case"-y, but here i'm just sorta like
Putnam3145: nah
Allis: Hm... what sort of special cases are you running into?
Putnam3145: everything's a special case if you turn off your brain hard enough
Allis: Well, sure, but you're better than that. :P
Putnam3145: just in code of the rings, there's the fact that the state of each individual part of the tape is correlated to but not equal to a proper char, to which my original solution was to make some manner of general lookup table for this but then i realized that i could just do a switch statement for the special case of 0 == \32 rather than the rest, which are 1 == \65 and 2 == \66 and so on
Putnam3145: i could've also general-cased this with x+(sgn(x)*32)+32, i think but that's somehow even worse
Allis: Hm... I just did `alphabet=[' ',*?A..?Z]` and then mapped the characters of the message to their indices.
Putnam3145: yes, well.
Allis: A lookup table, I guess, but that doesn't feel special-casey.
Putnam3145: sudden realization that i have to use the lookup table anyway
Putnam3145: cause it's on a cycle
Allis: Well, there's always modular arithmetic.
Gingsy: plz share code!
Putnam3145: please do
Putnam3145: it's the spirit of the thing
Putnam3145: i'm sure it helps people lots
_-: Allis Allis go away
_-: Come again another day!
_-: Allis, Please, choose stronger opponents pleaaaaaase!
Nicky1812: guys
Nicky1812: how to input 2 string on 1 one line by python?
Nicky1812: im a newbie :((
Allis: Seems like you're looking for str.split()?
zile151: ^, or input().split() if im understanding ur question correctly
Nicky1812: hmm
TwT: http://chat.codingame.com/pastebin/8a4831d3-2ef2-4eea-8292-45035187f8f5
TwT: if it is
-->Hello
TwT:
-->World
then you might be talking about [input() for x in range(2)]
Nicky1812: ok thanks guys
Nicky1812: but how about input "hello/word"
TwT: input().split("/")
Nicky1812: we can get "hello" and "word"
Nicky1812: okok thanks i have got it
TwT: look into split() online
Nicky1812: :grin:
_-: or help(str) on python interpreter
Putnam3145: am i allowed to get mad at how C and descendants define modulo
Putnam3145: let's take the simple example of (n%4)
Putnam3145: waitin
Putnam3145: wait wait
Putnam3145: lemme look up how C in particular does it
Putnam3145: I may be making the grave mistake of assuming C++ is a superset of C
_-: they are the same
_-: should be
_-: c++=c with classes
Allis: Thankfully, a lot of newer languages define it more sensibly, such that -1 % 4 == 3.
Putnam3145: yeah okay
Putnam3145: yes, I'm complaining about the definition that -1 % 4 == -1
Putnam3145: instead of 3
Putnam3145: also, they aren't the same
Putnam3145: haven't been since 1999
_-: Oh
Putnam3145: it *was* originally "C with classes"
Putnam3145: in the '80s
Putnam3145: then it evolved, a lot, and so did C, somewhat
Putnam3145: they diverged by C99
Putnam3145: ...though not significantly
Allis: You can use something like `(n+d-1)%d` to get the wraparound in languages that don't support it natively.
Putnam3145: obviously you can still use a lot of C headers in C++
Putnam3145: most, even
Putnam3145: or rather
Putnam3145: idiomatic C/C++ is such that if your file is a .h file, it should be readable by both C and C++
Putnam3145: that's just idiomatic though
Putnam3145: i deal with all this by not using C or C++ unless I can help it
Putnam3145: it doesn't help that I have to spin up a linux VM or computer to make working with either's toolchain tolerable
Nicky1812: how to change "helL" to "HELL" in python guys?
Putnam3145: the general term for that is "to upper"
Putnam3145: i don't know what it is in python
Putnam3145: to upper, or to capital
Sajori: 'hell'.upper()
Putnam3145: googling either will work, but to upper usually gets better results
Putnam3145: when did i start doing bracketless ifs
Putnam3145: what has happened to me
zile151: isn't bracketless ifs the "correct" python style
Putnam3145: yes
Putnam3145: I'm talking in D, which uses C-like if syntax
Putnam3145: actually I think it's specifically because I've been working on a project in C++ for a while?
Putnam3145: one that happens to use bracketless ifs hither and tither
Putnam3145: so I probably picked it up as part of the "project style"
Putnam3145: too bad
Putnam3145: the funny part is that bracketless ifs are actually WORSE in C/C++ than D
Putnam3145: on account of the C preprocessor allowing for some really horrible monkey business to happen with them
Putnam3145: if(c) return TRUEMODULO(a,b)
Putnam3145: whoops TRUEMODULO's got multiple statements so now you've got a bizarre error!
zile151: i dont use C much but i usually/luckily get syntax errors when i miss brackets from my experience
Putnam3145: sure, but
Putnam3145: if(b) dostuff()
Putnam3145: is perfectly valid syntax in C
Putnam3145: uh, if you
Putnam3145: add the semicolon I fatfingered away
Allis: Multi-statement macros should be wrapped in a `do { ... } while (0)` to avoid that particular brand of surprise.
Putnam3145: thank nearly 5 decades of continuing development for compilers that generate identical code when you do that
Allis: I'm not sure I follow. That's a purely lexical thing that compilation doesn't really enter into.
Allis: It works as long as the compiler correctly executes the body of a do loop at least once and doesn't interpret 0 as truthy.
Putnam3145: yes
Putnam3145: i'm saying that a modern compiler won't even generate a jump for that
Putnam3145: it'll figure out that the inner block runs once
Putnam3145: so any premature worries about "optimization" can be ignored
Allis: I see.
_-: How to disable editor tooltips. It's really annoying sometimes.
Allis: There's no native option, but you can be rid of them with a user stylesheet.
Allis: I personally use the Stylus extension.
_-: Tell Me
zile151: hey Allis, for the clash where you output the first 3 digits of a to the power of b, does ruby somehow optimize the calculation?
zile151: for python if you do like str(a**b)[:3] it times out
Allis: That's interesting. I just did `(a**b).to_s[0, 3]` and didn't even realize I was getting away with anything.
Allis: You're quite sure your inputs were correct?
zile151: well it passes all the test cases except the last one which is like 109^900000
zile151: i mean i still got 100% but i had to do this: http://chat.codingame.com/pastebin/b43486e8-51e8-4977-a3ec-b8a9651e7b61
Allis: I can confirm that that operation is a heck of a lot faster in Ruby.
Allis: So yes, the interpreter must be doing something clever under the hood.
zile151: yep, thanks for replying!
Allis: No problem.
_-: Allis can you please share your settings. I dunno what to do
Putnam3145: oh dear
Putnam3145: i've made a working thing for code of the rings
Putnam3145: I thought I'd coded it so that it'd properly go - or +, whichever's faster
Putnam3145: and yet
Putnam3145: the working version, for AZ, is
Putnam3145: `+.+++++++++++++++++++++++++.`
Putnam3145: it works, but it's, uh, not ideal
Allis: Oh, that's no good.
Allis: @_- If you've got a way to use custom CSS, you just need: `.editor-widget { display: none; }`
Putnam3145: speaking of being unable to google things
Putnam3145: what the hell is the proper term for "modular distance"
_-: Are you in a "vow of ungoogling" or something?
Putnam3145: the function such that f(26,1,27) == 2
Putnam3145: no
Putnam3145: opposite
Putnam3145: I can't figure out what to google to get a proper way to do that
Putnam3145: every attempt at writing it myself has failed despite it being seemingly simple math
_-: manhatton distance?
_-: what is it you are attemting?
_-: attempting*
jrke: attempting what?
Allis: @Putnam3145 That's just `(b-a)%c`, no?
Allis: Since it doesn't make much sense to speak of negative distance, probably there's no clear-cut definition of "modular distance" either.
Allis: The wraparound is kind of implicit.
Putnam3145: it makes sense to speak of negative distance in the case where direction matters
Putnam3145: and this is that case
Allis: You gonna print -8 minus signs?
Putnam3145: I am going to print 8 minus signs if the distance is -8
Putnam3145: and if it's 8, I'm going to print 8 + signs
Allis: No sense getting caught up in linguistic rigmarole, so I'll just point out that you're definitely on the right track.
Allis: If your language has something like min_by where you can calculate the minimum based on some predicate, you're golden.
Putnam3145: turns put my closestToZero function was just hilariously wrong
Putnam3145: there, now it outputs +.--.
Putnam3145: yay
Putnam3145: in fact it passes all tests
Putnam3145: now, to make it Better
_-: Thanks. I will report it.
