zophia2222: hey ppl
C26_1: @zophia2222, hello
C26_1: And I have a very small puzzle fỏ you guys
zophia2222: how is my fave ppl
C26_1: Given a binary string, compute the index of the longest chain of 1
C26_1: For example:
C26_1: The output is 3
C26_1: Because the longest chain of 1 is 11111
C26_1: and it is the 3rd chain in the binary string
C26_1: Clarify: the chain can also be a single '1'
C26_1: For example: 011010
C26_1: The second chain is '1'
zophia2222: ok try this 0110111
C26_1: If there's multiple same-longest chain then compute the smallest index
C26_1: @zophia, output is 2, cuz the longest chain is 111 and it's the 2nd chain of the binary string
C26_1: I think the better terms here is trailing of 1
zophia2222: two would destroy the whole code
C26_1: idk if everyone here has played Comaandos: BEL before
C26_1: Bc it was fun and thinking more some strategies
zophia2222: do you know what ditto means?
zophia2222: thank you
zophia2222: I speak Spanish too!
zophia2222: Ello mate
zophia2222: plz talk to meeeeeeeeeeeee
zophia2222: thank youuu
zophia2222: I need night chat since my parents are asleep
zophia2222: wontonio wanna chat?
Wontonimo: a friendly reminder of the general gist of the rules here: be respectful, talk about coding or codingame, stay mostly on topic.
zophia2222: ok just wanna talk about coding games?
zophia2222: with me?
zophia2222: hi guys
zophia2222: yall up?
zophia2222: CUZ I WANNA YALK ABOUT CODING GAMES!!!
zophia2222: my buddy's let's talk!!!!
zophia2222: antonypadella let's talk meet me on private chat and really just talk ok???
Uljahn: pls don't flood
zophia2222: just follow me
Uljahn: why are you lvl 3? do you even code?
zophia2222: yes I do retrtdrtrr
zophia2222: I will flood u
Uljahn: you've been warned
zophia2222: about what? I need to chat@!!!!
zophia2222: can I be like y'all so I can kick
Uljahn: this chat has rules: https://www.codingame.com/playgrounds/40701/help-center/code-of-conduct
Uljahn: "Don't spam nor flood the chat with non-sense, jokes or private discussions. While CodinGame and its community are free to access, it doesn't give you rights to make it your playground. It's a shared space."
zophia2222: ok I just wanna be like y'all I wanna be cool like y'all can I plz be like y'all and kick @ulijahn
Uljahn: you can't be promoted to a moderator while being lvl 3
Uljahn: you need a ton of experience
zophia2222: thank you
zophia2222: oh sorry
zophia2222: I thought you said I can\
Uljahn: also spamming in DMs is not the best way to become a moderator
zophia2222: ok I'ma try to lvl up
Urutar: Do or do not, there is no try.
Urutar: Star Wars reference...
Urutar: Based on your earlier message.
zophia2222: well do you wanna do a coding practice
Urutar: Sure, why not
Urutar: No idea, I mainly use C#
Thorcode: hi Automaton2000
Automaton2000: i guess it was just the first thing i did to get to the next checkpoint
zophia2222: hi guys
Thorcode: who make you Automaton2000
Automaton2000: but still my rank is not climbing
Urutar: Greetings Automaton200
Urutar: Greetings Automaton2000
Automaton2000: i guess it's just a way to make that work
Urutar: zophi2222, please don't spam.
zophia2222: I won't I promis
Thorcode: you could type zop+"tab" to mention her
YS_Yousef: hi urter
zophia2222: everybody up at 1am
Urutar: Well, it's more like 8:25 am over here
zophia2222: are you serious I'm up at 1am who else?
Urutar: Nah, I'm not serious, I'm Urutar.
zophia2222: wait are you the one I'm talking to right now?? \\\
Urutar: Alright, I'll wait. (and I think so?)
zophia2222: anyone else
Uljahn: enough chatting for you
Urutar: Oh, was that a permaban or a temporary one?
Uljahn: want to be next?
Urutar: No. I'm just curious.
Uljahn: you'd better be curious about coding
Urutar: I am; that's why I clash a lot :)
Urutar: Is it actually possible to block private chats? E.g. if I wanted to mute someone?
Uljahn: maybe if you use external clients
Urutar: Oh well, not gonna do that.
Urutar: Hm, is it possible to ban someone completely?
Uljahn: it's possible to ban ip adress
Urutar: Oh well, that problem will probably solve itself sooner or later. But thanks anyways^^
C26_1: Oh hello
Urutar: Greetings, all ye good folks :)
C26_1: I have a problem with my problem
Uljahn: just solve it [solved]
Urutar: Helpful mod is being helpful, indeed :)
Urutar: C26_1 Do ya still need help?
YS_Yousef: hey urutar
Urutar: Heya YS_Yousef
YS_Yousef: can u see my contribute because ur level is high so ur feed back is important :thinking:
Urutar: Anyone can reach a high level if they do a lot of stuff on codingame :D
Urutar: And yes, I can see it^^
Nachosauce: That's really all it takes for ranking too. The only thing I'm pretty alright at is the mad pod racing but since I've done things across lots of areas I'm still top 0.6% global :joy:
therealbeef: 95% is inactive orso
Urutar: Yeah, that's my experience aswell - I'm curious about the spring contest^^
Urutar: Might even reach the top 0.1% that way^^
Nachosauce: oh I'm so excited for that. I played a few of the old contests (recently, not while they were active) and they're great
Urutar: Hmm, at some point I'll check those out^^
Nachosauce: fall 2020 challenge is amazing
FiveAm: Hi all, anyone knows how contest works ?
Nachosauce: I do not. The upcoming one will be my first
Uljahn: i think CG is moving to more frequent but less global events, so new bot ai contests are kinda unlikely
Urutar: Hm, how can I actually take part in the old contests? Or rather, see the statement etc.?
Uljahn: past contests are available in multiplayer section, yes
Urutar: Thank you :D
therealbeef: contests are like the multiplayer games but more fun because of the time limit, and there is no established knowledge yet, so everyone is rushing to figure out what works best (and then spends the other half of the time debugging their rush code)
Nachosauce: How effective is the plugin to use an external IDE? I would love the better features of a better IDE but like the quick feedback of using the codingame one
therealbeef: the syncing is pretty ok (little bit lagged sometimes), and you can set an option to play a match every time you save
Nachosauce: ohh nice. Maybe I'll give it a whirl
Nachosauce: Everytime I try to introduce shield to my mad pod racing everything goes wrong :joy: I've got some debugging to do.. my pods just want to spam shield even though that should score really low on most turns. Something is wrong somewheres
Uljahn: i only use shields when a collision is imminent and velocity difference is higher than some tolerance, also frontal collisions are mostly harmful while rear collisions could be advantageous
Uljahn: everything is difficult when you have zero experience
Rebollo: Hello folks! I would like to talk about the resistance puzzle:
Rebollo: does anybody have some tips about it?
Rebollo: I am not a expert but I know how to learn things by my self... I have my own rhythm, which is not very fast but I can evolve my skills.. I would suggest to elect any kind of problem and try to solve it coding... Choose any language you want and google all the concepts you need to solve it..
Rebollo: let´s say you want to create a program to check if the number is even or odd..
Rebollo: so, with this simple problem you can lear a few importat concepts
Rebollo: 1 - how to print values on the screen 2 - how to use if and else statements
Rebollo: So you are in the right way..
Rebollo: Lets choose another problem so you can learn the concepts to solve it..
Rebollo: Lets think about something simple that uses LOOP
Rebollo: What are you struggling with?
Nachosauce: No, you need a solution to solve all the test cases :)
Rebollo: your code should be generic enough to be able to solve every proble
Rebollo: it seems that you need to sort the values
Rebollo: let me check your code
Rebollo: could you sahre it?
Uljahn: that's called hardcoding
Rebollo: which language???
Milanovich: You will have to process some of the input listed in the problem statement, like so: x = input()
Milanovich: Looks like python 3
Uljahn: hardcoding is when your program is independent of inputs, so behavior is not flexible
Rebollo: Do a quick exercise in order to learn a few concepts of loop
Rebollo: you see this: for i in range(8):
Rebollo: it means that it will repeat everything inside it, 8 times
Rebollo: and will provide you the row it is executing in the i variable
Rebollo: so first thing:
Rebollo: print the i variable inside the for loop I have a loop at the behavior
Rebollo: remeber it starts always with 0
Rebollo: so 0 to 7
Uljahn: not always but by default
Rebollo: thank you
Rebollo: doa print(i) inside the loop and check the behavior
Uljahn: i don't think this chat is the best place to teach the basics of python though
Rebollo: doa print(i) and it will clarify a few things
Uljahn: also you can use the hints tab on the left side
Rebollo: uderstood the behavior? At least you get rid of the hard code
Nachosauce: Definitely don't give up. It gets so much easier as you practice. It's hard to make that jump from knowing the basics to applying them, but once you get the ball rolling it goes FAST :)
Uljahn: don't do print(i), use print to error stream as said in the commented lines
Rebollo: twice? didnt happened to me
Rebollo: let try to make A little bit more generic solution
Rebollo: yes so it can be used for every situation
Rebollo: you pass aall the tests?
Rebollo: choose another problem and keep going
Rebollo: don´t forget that the goal is always to learn
Rebollo: forget about averything else
samadh90: And enjoy
Rebollo: is it possible to sent a private message to someone I am following?
struct: just follow each other or click on their name on this chat
Rebollo: Humm I think he is not following me
Rebollo: Anyone has solved the Resistance?
Rebollo: Could you give some help?
Rebollo: I am able to find the words
Rebollo: even with the largest dictionary
Rebollo: I am basically doing this:
Wontonimo: this is a "very hard" puzzle
Wontonimo: i work on this for several weeks.
Wontonimo: it is supposed to be hard
Rebollo: reading the message string, letter by letter, till I find a word in the dictionary...
Wontonimo: it's more like a mini research project, so no, I'll not spoil it.
Rebollo: I see give a tip only
Rebollo: If I am able to identify all the words in the message and its related indexes
Wontonimo: if you want to work on "very hard" puzzles be prepared to put in 40 hours or more on it if you find "medium" puzzles easy.
Rebollo: I am working like 2 weeks
struct: 40 hours o.o
Rebollo: very haard
Rebollo: If I am able to identify all the words in the message and its related indexes, how do I have to count it?
Rebollo: I mean, the message should fill all the string length
Rebollo: Or one word, at the begining, counts as a message?
Wontonimo: it has to use all the message
Rebollo: I am wondering how I am going to reach such a large number than..
Wontonimo: that is the whole puzzle Rebollo
Rebollo: I find a word..One one side I keep lokking for other word with the sames starting poing, on the other side I call the function recursivelly and do the same..
Rebollo: till I reach the end
Wontonimo: something that helped me was to make a naive solution that I was sure worked even through it took too long. I used that to make more test cases for myself while I worked on the high effeciency verson
Uljahn: the forum thread has some hints such as using memoization
Wontonimo: i never read the spoilers :O
Rebollo: I checked all messages but could figure out what the point..
Wontonimo: other than for multis ;)
Wontonimo: struct, you reacted with o.o for 40 hours. what's your take on 'very hard' puzzles ?
Fasader: O.O I guess
Rebollo: maybe o.O
Wontonimo: (that's me throwing up my arms, not laughing)
Stilgart: actually, the hardest puzzles are in hard
Fasader: what about the softest
Stilgart: and several "very hard" puzzles are not so hard
Fasader: easiest are in coc :D
Stilgart: did anyone knows about a recent change for swift ?
Stilgart: it seems some of my swift codes are tagged "Swift3", while the others are tagged "Swift"
Uljahn: some my bots are still python 2
Stilgart: might be like the python(2) VS python3, but I am not aware of such change for swift
Stilgart: moreover, there is only "Swift" in the API I am used to play with (while there is python and python3)
ninjadip: kill all humans
ninjadip: err i mean hello all
Stilgart: that's a job for Automaton2000
Automaton2000: i heard that, lsmith-zenoscave. i'm not ready
Mrs.GloriaZindlebocker: what a horrible puzzle
Wontonimo: "I'm not ready"? oh Automaton2000 that is good to hear, but it implies you are getting ready
Automaton2000: but it's very simple and fun.
Stilgart: Automaton2000: you still might need a few turtles
Automaton2000: no, what i mean :p
Stilgart: (╯°□°）╯︵ ┻━┻
Uljahn: Automaton2000: kill all humans, spare cats :smiley_cat:
Automaton2000: you don't need to remember what i did at first
Wontonimo: you better hope Automaton2000 didn't confuse "spare" for "spade"
Automaton2000: doesn't sound like a dick
Wontonimo: /kick Automation2000
Wontonimo: well, language Automaton, language!
Wontonimo: chatbots theses days
AntiSquid: someone must had their way with the bot, otherwise it wouldn't know what one sounds like
Stilgart: according to the forum (and to dwarfie), Swift and Swift3 have coexisted for some time, and when swift was updated from 2.x to 4.0, swift3 was removed
derjack: sounds like winamp
Wontonimo: you can't cancetin57. do puzzles instead
Wontonimo: most of the other "players" in Clash are bots and not real people btw
Mrs.GloriaZindlebocker: are you advising cancetin57 to ignore the quest map?
ninjadip: the other players in clash are bots?
ninjadip: that blows
ninjadip: why do u say obviously
Uljahn: bots could be easily detected by the number of clashes played
jacek: or addicts
justchris: im def addict, might be a bot too
justchris: speaking of bots, anyone tried talking to emerson ai?
ninjadip: on an emerson smart tv?
justchris: xD on telegram
jacek: Automaton2000 on telegram?
Automaton2000: i would like to know
ninjadip: never heard of telegram
ninjadip: i did mess with AI dungeon i think it's called.
ninjadip: that was interesting...
justchris: Dialing the AI...
ninjadip: prank call it!
Rebollo: Guys, how can I synchronize my IDE coding Game code to visual studio?
Rebollo: It was working
Rebollo: but I can´t syncronize anymore..
ninjadip: i didn't know u could do that
ninjadip: love my visual studio
Rebollo: Left side of the screen u ill find setting
Rebollo: just turn external code editor on
AntiSquid: ninjadip if you are using facebook and twitter, close your accounts and consider telegram as an alternative
Rebollo: I just don´t know if its possible to run the program directly from the visual studio code
Rebollo: A cmd prompt get opened
ninjadip: AntiSquid i don't have an account on any of those
ninjadip: probably why i didn't hear about telegram
Rebollo: but am I supposed to fill up manually?
ninjadip: unless you're in new jersey
AntiSquid: that's good ninjadip
Rebollo: Does anybody know if it is possible to run the program in Visual Studio Code and import the TESTCASES parameters?
Lambert_W_Function: lambert w function
Euler_Phi_Function: euler phi function
Stilgart: Rebollo: it seems technically possible, but I won't write a vscode extension for this
Rebollo: I realized that there are a configuration , like, a "work around" for this "issue"..
Rebollo: there is
Rebollo: A configuration flag that runs the application automaticaly in the browser once you save the code in the local editor..
Rebollo: update the code and run the test cases in the browser..
Rebollo: it´s ok
Rebollo: but I was looking for better error/warning messages
Rebollo: So this functionality doesn´t solve all my problems;;
Rebollo: As well as debugging the code..
Stilgart: you might want to take a look at https://www.codingame.com/forum/t/codingame-sync-beta/614
Stilgart: at least this allows you to compile your code locally
Rebollo: thanks I ill check it
Stilgart: but there is no tool (yet) that fetches the test cases and allows you to run them locally
Stilgart: imho, such tool is too much effort compared to copy-pasting the test in a local input.txt file
Stilgart: (and the integration within vscode is yet another story)
Rebollo: sure but this kind of details is what makes this platform amazing
Rebollo: Like I used to use Hackerhank
Rebollo: and Coding Game is wayyyy better
jacek: nabaztag the pragma things should be the first line, above the includes
justchris: does anyone know if it is okay to use part of a library to solve a puzzle?
Mrs.GloriaZindlebocker: one of librarians probably knows
Wontonimo: yes, go ahead and use a library justchris
Mrs.GloriaZindlebocker: good for you, make them wait
Thorcode: bruh we can use mosst library on this site
Wontonimo: heyyyyy thorrr, how's your day going?
ASM_MOV_INT: Thor controls the sky... can we get some sunlight here please? rofl
Wontonimo: i thought it was just thunder he controls ?
Wontonimo: all through the
ASM_MOV_INT: maybe it's just lightning?
Wontonimo: it is definitely "Thor the god of thunder" and not "Thor the god of maybe just lightening"
Wontonimo: who are you?
Wontonimo: how did you get here?
Thorcode: I can only control thunder not weather
Wontonimo: we all have our limitations Thor, don't let it get you down.
Wontonimo: that's brave of you emergenitro
DaShogun: How do you change ur codin language
Wontonimo: a lot
Wontonimo: and practice a new coding language
DaShogun: No i mean in this site
Wontonimo: the one day you can find the dropdown at the top of the page
Wontonimo: that has a list of languages in it
Wontonimo: around the centre top
Wontonimo: when you are coding
Wontonimo: look at your code .... then look up
Wontonimo: you'll see the language with a "V" symbol beside it
Wontonimo: no one knows what the "V" means, maybe "View this list" or "Venture to other options", but
Wontonimo: you click that area with the "V" in it and a dropdown appears
Wontonimo: it's magic
Wontonimo: maybe it is latin
Wontonimo: did you find it DaShogun ?
Wontonimo: hmm , Dashogun left us. ;(
Wontonimo: have you tried bot battles emergenitro ?
DaShogun: Im here
Wontonimo: what's your coding skills like? do you think you could write a basic Tron bot that turned right before crashing https://www.codingame.com/multiplayer/bot-programming/tron-battle
Thorcode: don't let them try the tron ballet wonton
Thorcode: I'm hack?
Wontonimo: will Tron escape if you make him too powerful?
Wontonimo: back, not hack.
Thorcode: ah my bad
Wontonimo: why no Tron battle Thor?
Thorcode: why not cbs wonton
Thorcode: Tron is pretty hard
Wontonimo: why? Just turn left (or right)
Thorcode: nah to get to gold or silver need a lot of brain
Thorcode: like space management
Wontonimo: gold !?! way to set your expectations so high!
Wontonimo: what ever happened to people being happy to have reached bronze?
Thorcode: ah yeah just turn left or right
Wontonimo: I'd suggest left, it's better
Thorcode: But they can easel.ly get to gold or silver in mad pod race
Wontonimo: if you tell them "the secret". without that gold is actually pretty hard.
Wontonimo: and even if you -3V hide the secret in -3V plain sight they won't -3V what it means.
Wontonimo: hey, that emoji didn't show properly
Wontonimo: oh well ;)
Wontonimo: yuck yuck yuck
Thorcode: nah the emoji can't
Wontonimo: i was joking Thor ... come one man
Wontonimo: throw me a bone
**Wontonimo looks at bone Thor drops on floor then to Thor questioning the God of Thunder's ability to throw
**Thorcode slaps everyone around a bit with a large fishbot
Thorcode: seeking to get 250xp more
Thorcode: https://www.codingame.com/training/hard/wave-function-collapse-sans-shannon the first puzzle has a cool tag I ever seen
Wontonimo: thanks man
Thorcode: what there is another reading statement tag
Wontonimo: yeah, this one is a monster of a read
Wontonimo: very precise instructions. not a lot of instructions but precise
Thorcode: yep this puzzle statement makes me dizzy
Wontonimo: it's pretty cool tech. it can turn this
Wontonimo: into this
Wontonimo: or given a style of maze
Wontonimo: it can generate arbitrary mazes like this one
Thorcode: https://www.codingame.com/share-replay/603591809 lucky rocket
Wontonimo: nope, i'm "not authorized" to see your lucky rocket
Thorcode: how strange
Wontonimo: and now that i think about it, I'm not sure i want to see your rocket :unamused:
Thorcode: nah it is the rocket of mars lander
Wontonimo: okay then
Thorcode: I was scare when see at 94
Thorcode: how can I identify the cave at the second testcase?
Wontonimo: what do you mean "identify"?
Wontonimo: first, tell me how your lander current looks for obstacles and works ?
Thorcode: it just land straight to the float land
Wontonimo: show me a replay of cave 1
Thorcode: like the one I show you
Wontonimo: you didn't, i never saw it. it was access deniced
Wontonimo: also de-nice-d
Thorcode: can you access it?
Wontonimo: how did that not crash?
Mrs.GloriaZindlebocker: is that the one with the bad widths?
Wontonimo: i saw it
Wontonimo: it totally flew through the top of the cave
Wontonimo: you have mad skills
Thorcode: the 94? move
Mrs.GloriaZindlebocker: oh, I thought you were still talking wfc
Wontonimo: anyway, so you don't actually check for collision?
Thorcode: that why I say that my rocket is lucky
Wontonimo: oh, there are bad widths Zindlebocker ?
Mrs.GloriaZindlebocker: I didn't check
Wontonimo: yeah, lucky rocket. that luck ain't gonna carry you through for cave 2
Wontonimo: so, you'll have to probably detect collision
Wontonimo: and do a look-ahead
Wontonimo: my algo relies on a scoring function, the lower the score the "close" to landing
Wontonimo: so coming up with a good score is key. just distance to the landing pad will make you crash into the cave for cave 2
Wontonimo: so, for distance i first do a flood fill of the map that goes around the cliffs. it starts at the centre of the landing pad and radiates out
Wontonimo: just calculate it once.
therealbeef: for crashes and landing, the point that counts is right in between the two 'feet' of the rocket, not a bounding box or something
Wontonimo: interesting. thanks
Wontonimo: hey therealbeef, good to see ya
Wontonimo: for crashes I didn't actually use physical crashing, but once I have detected that there is no chance of survival, no matter where the rocket is, i consider that it has crashed.
Thorcode: I'm done with very hard puzzle
Wontonimo: you have invoked the holy word, I must stop what I am doing and understand your pov
Wontonimo: meh, or not
Thorcode: I may luckier with the resitance
Wontonimo: ! what ! twice ! How powerful are you to be able to chant it twice in such a short time. I tremble in your presence
Thorcode: what word?
Wontonimo: what kind of cooldown do you have on your "bruh" power word ?
Thorcode: I dunno
Thorcode: and what is pov?
Wontonimo: point of view
Wontonimo: tis my lander
Thorcode: how can't it crash
Thorcode: at 107
Wontonimo: you are not the only one who has mad piloting skills
therealbeef: Hi Wontonimo! Yeah I moved 8 timezones so I don't see a lot of the usual people in the chat anymore
Wontonimo: what have you been up to?
therealbeef: on CG: spring 2021 contest, and code4life
therealbeef: neither very successful ;)
Wontonimo: i have fun with spring 2021
Wontonimo: i didn't do the usual beam search
therealbeef: i tried to use convolution neural networks with alpha-beta, and found out that it is a bad combination
Wontonimo: sounds like it would have been pretty good
therealbeef: my theory is that alpha-beta really needs fast eval
therealbeef: so hand-written eval or very small neural network worked better than deep learning
Wontonimo: it does perform better with deeper search
Wontonimo: convolution is expensive
Wontonimo: in compute resources
Wontonimo: so it has to pay for itself more than the extra depth from a more simple eval
therealbeef: indeed. while with mcts you first roll out to a deeper level (semi-)randomly and then only do the eval once
Wontonimo: did you write your own CNN?
therealbeef: so thats more efficient use of the evals
therealbeef: yes, the eval part
therealbeef: c++ doesn't have libs for CNN on CG
therealbeef: offline learning i used tiny-dnn
Wontonimo: yeah, but i thought marchete shared some lib he made specifically for CG
therealbeef: is it allowed to copy code from someone else into CG?
Wontonimo: he made it to share. it is just a lib. you still have to understand it, integrate it, run your own sims locally, come up with your architecture, your own search ... so yes, i'd say a strong yes
therealbeef: hmm, i always thought it wasn't allowed
therealbeef: otherwise i could copy-paste boost or eigen into my code
Wontonimo: don't go copying 95% of someone elses solution dude. you can't claim to be the real beef if your don't supply at least some of thhe beef
therealbeef: anyway it was interesting to write the eval code myself, using simd
therealbeef: single instruction multiple data
therealbeef: vectorized calculations
therealbeef: was nice to learn it :)
Wontonimo: oh, yeah. that is very rewarding to get nailed down
Wontonimo: i wouldn't know though. only read it in a fortune cookie
therealbeef: rewarding and frustrating ;)
therealbeef: at that level it's not always predictable what gives performance increase and what doesn't
therealbeef: simplicity of the code seems very important, for example
Wontonimo: hi Hackker
therealbeef: but i don't mind; learned something new, now got a bunch of new code to be used in other contests. no rush ;-)
Wontonimo: yup, that's the way it goes
ASM_MOV_INT: simd is assembly language
ASM_MOV_INT: cool stuff, haven't thought about that in a while
