Waffle3z: clash of code is an event now?
Mohamed_Kharrat: PatrickMcGinnisII thanks man, although I did end up solving it with recursion just like knapsack, I used a dictionary
Mohamed_Kharrat: turned out easier than i thought
PatrickMcGinnisII: of course u did. :clap:
Mohamed_Kharrat: :D
PatAPizza56: how do we invite redninja???
Mohamed_Kharrat: i invited both of u
Mohamed_Kharrat: 30 sec left
Mohamed_Kharrat: tick
Mohamed_Kharrat: tock
Mohamed_Kharrat: have to go get some sleep bye guys
Andy12: HEY.
Andy12: hi
RandomSteve: hello there
Redninja106: WHATS UP EVERYONE
RandomSteve: not much, how you doing?
RandomSteve: I'm working on the temperatures puzzle
Redninja106: well thanks!
Redninja106: im in COC right now!
RandomSteve: cool
RandomSteve: yay I solved it
RandomSteve: :)
RandomSteve: I kinda have a trauma becaus ein the puzzle shadows of the knight everytime I tought I had it I didn't have it but this time it actually worked
RandomSteve: now I actually feel like I am learning and taht I have learned a lot
RandomSteve: thanks to all those people that showed me support
PatAPizza56: hey everyone!

jacek: happy Caturday
jacek: oh my https://www.deepmind.com/publications/a-generalist-agent
DomiKo: published 2 days ago?
jacek: 12 may
DomiKo: ohh ok I see
MSmits: hey, I just had a really good idea about my local meta mcts
MSmits: I switched to a normal mcts (with book lookups) for my local and it only did 200-300 rollouts/second because it has to take the data from the drive
MSmits: So I made a shadow-dictionary that caches all the data on the drive that is being used with a capacity of around 1M. I do everything from that cache and flush it when it reaches 1M. It sped my program up a factor of 10!
jacek: now do it in GPU
MSmits: no way :P
jacek: i finally hunted down the bug, but i still dont know why it happens in the first place
MSmits: weren't you at that place already or is this a different bug?
jacek: i was, but it reappeared when i added another car
jacek: i learned some of the gdb
jacek: i assumed it was some null pointer
MSmits: oh ok
jacek: but it isnt, the pointer points to some deleted object
MSmits: weird
jacek: but i dont see at code why it would happen
jacek: and it still happens once in few hours
jacek: i was lucky i caught that while in gdb
jacek: $57 = {<Point> = {x = -1.0228604160514661e+263, y = 479.0564462702327}, _vptr.Unit = 0x7fffdc000, id = 0, vx = 132, vy = 100, beforeColvx = 132, beforeColvy = 100, radius = 100, mass = 1, friction = 0}
jacek: nice x
MSmits: oh yeah
MSmits: I think i know what happened
MSmits: the car went to a different universe with the same y coordinate
MSmits: but same x
MSmits: different x that is
MSmits: there's a wormhole in your code
eulerscheZahl: would be cool if you can somehow apply that concept in the real world
MSmits: Like pointing to something that doesn't exist and then you're teleported to a different universe?
MSmits: That's be fun
MSmits: 'd
RivalRickson: hi
rabee12: hi
jacek: finally i found it!
jacek: it was pointing to the beginning of vector. but if you add something to the vector, it will resize and copy and the address will be invalid
jacek: stupid c++ and its memory management
DaNinja: that auto resize can be extremely annoying. it breaks references as well as pointers
MSmits: ohh that is indeed annoying. I haven't had this problem because I use vectors as a cache with a large capacity at the start
MSmits: good to know that this can happen
Teerach: heloooooooooooooooooo
Teerach: helloooooooooooooo*
ben517: do private clash of code games affect your rank
bojgus: no
ben517: cool thanks
therealbeef: it's basic property of std::vector interface :-/
struct: jacek does that happen only if the vector gets empty and then add something?
therealbeef: "If the new size() is greater than capacity() then all iterators and references (including the past-the-end iterator) are invalidated. Otherwise only the past-the-end iterator is invalidated."
struct: so if I had vector<int> vec(1);
int* p = &vec[0];
and then add more than 1 int, it will cause problems?
therealbeef: depends if capacity is also 1
struct: isnt vec(n) the capacity?
struct: or is it something else?
therealbeef: n is the size
TINOUAINANI: Top 50 or delete :grin:
TINOUAINANI: :joy:
therealbeef: capacity is the size of the reserved memory
struct: vector<int> vec(1);
cout << vec.capacity() << endl;
vector<int> vec2(2);
cout << vec2.capacity() << endl;
struct: 1
2
therealbeef: most implementations apparently set the initial capacity to the initial size, but the standard doesn't specify anything
struct: ah ok
struct: thanks for explaining
therealbeef: a high-performance implementation could use a small initial stack array for example
jacek: struct it happened when i added 3rd ball to vector of capacity of 2
jacek: i never knew there could be 3 balls during collisions handling
jacek: this is what you get when copying code straight from java
TINOUAINANI: Ho did puzzel named "Bank Robbers" , i am stack in last test with slite differnece in the resulte ?
5DN1L: Probably because your solution is wrong?
TINOUAINANI: my be not , may be i lose some peregent becouse the resule is so close
jacek: oO
5DN1L: btw what language are you using? is that English? TINOUAINANI
TINOUAINANI: :joy:
TINOUAINANI: i am lezy to use tradiction sory hhh
jacek: :thinking:
5DN1L: that's a language puzzle
TINOUAINANI: Q : if you whant to find number of combination of password thats 3 first characters are digit and the last tow are from [a,b,c,d] ?
TINOUAINANI: the result is pow(10,3)*pow(4,2) wright ?
5DN1L: it took me a few seconds to interpret tow as two...
5DN1L: wright
5DN1L: i mean, right
TINOUAINANI: no percegent lose right ?
5DN1L: sorry, no idea about what you're asking
5DN1L: translate it for me
5DN1L: thank you
jacek: hm?
emyilmaz: holaaa
Husoski: TINOUAINANI That's correct, provided that repeated characters are allowed.
Husoski: With no repetitions, its C(10,3)*C(4,2)
Darleanow: Hello gello
Darleanow: 5DN1L
Darleanow: i need u bro
TINOUAINANI: ok thanks
Darleanow: i'm doing 1d fire bushes
Darleanow: i've made a regex
Darleanow: to split by 3 all the bushes and its working, almost
5DN1L: Don't ask me about regex :scream:
Darleanow: for some the quantity of bushes isnt dividable by 3 xD
Darleanow: https://www.codingame.com/ide/puzzle/1d-bush-fire
Darleanow: U SHOULD LEARN AT LEAST THE BASICS !!
5DN1L: :cry:
zakacat: Give :taco: 5DN1L
Ayza: still suffering darlean lol
5DN1L: what is the logic of your code, Darleanow?
Tien118: taco?
Husoski: Darelanow This is a simple loop to write without regex. WIth regex you have the problem of a fire in a final string of length 1 or 2.
Ayza: someone did solve this puzzle with one line of regex
Ayza: but it's not necessary
Husoski: Sounds like someone has a golf complex.
Darleanow: Hello Ayza and Husoki !!
Darleanow: idk what you're talking about --'
Darleanow: 5DN1L it searches for f's in strings cutted in 3
Darleanow: but i just need to know like when u split a string
Darleanow: if like it has not a length of 3, how can i get the last part of this string
Husoski: I have an idea to try in the IDE...brb
Ayza: I didn't split the string for my solution
5DN1L: that regex solutions checks for end of word boundary
5DN1L: solution*
Ayza: didn't seem to work out easily
5DN1L: or rather, end of line boundary i think
zakacat: Is there a way that I can do only fastest claseh?
Darleanow: mmmh
zakacat: *clashes
5DN1L: Join clash event or do a private clash
zakacat: nice, thanks
Husoski: Okay, regex is pretty easy but probably wasteful, CPU-wise. The leftmost fire must be put out, no matter what, right? Think about what happens after that.
5DN1L: np :)
zakacat: Oh, I got it apparently anyways. whoop whoop
Darleanow: Husoki i didnt understood everything
Darleanow: like leftmost etc
Gedela: taco
jacek: :upside_down:
jacek: Automaton2000 where is he?
Automaton2000: yeah but it's not the case
jacek: round and round https://streamable.com/op6fsl
TINOUAINANI: new puzzel "Calculator"
struct: now all you need is to avx the sim
ChrisKoehlerjr: can anyone help me with some puzzles
VirtualRealityRocks: I code C# too ChrisKoehlerjr , what do you need?
isaadi: AAAAAAAAAAAAAAAAAAAAAA
isaadi: mfw C
isaadi: pointers
TINOUAINANI: hhhhh pointres are great :joy:
TINOUAINANI: 1/a = 1/x1 + 1/x2
TINOUAINANI: is there a formola that faind all x1 and x2 that that fitting this eqution ???
TINOUAINANI: ps : x1 and x2 are unknown
j4at: http://chat.codingame.com/pastebin/f70e8513-9df6-4955-8e25-87c5643ccea7
j4at: Didn't test it, but even if i made a mistake the idea is there
j4at: TINOUAINANI
jacek: assuming x1, x2 != 0
j4at: well in our case its !=0 :3
j4at: Didn't bother write the prove
j4at: proof*
j4at: (forgot to remove x1=x2=0)
j4at: and a=[] lol
TINOUAINANI: i test your programme is,s working but what if x1 and x2 are great than a ?
TINOUAINANI: for ex your program
TINOUAINANI: 1/2 = 1/1 - 1/2
TINOUAINANI: but i whant those ?
TINOUAINANI: 1/2 = 1/6 + 1/3
1/2 = 1/4 + 1/4
TINOUAINANI: ist apuzzel named "Unit Fractions" that till this
j4at: ops made a mistake
TINOUAINANI: thi problem that they rich number big us 999999999 so thir is some thing with out for loop with i++
j4at: Well you can break if x2>2
j4at: incase of positive x1 and x2
j4at: http://chat.codingame.com/pastebin/0078f6c3-00aa-40be-9a91-a5465cce94ac
j4at: Didn't test it again
j4at: This works if x1>0
j4at: http://chat.codingame.com/pastebin/8a68c74a-2d2b-4ec7-9819-9a91dc9b41cc
j4at: if a > 0 then a small change will make it work on all cases
j4at: I helped enough you can guess the reset alone
j4at: TINOUAINANI
TINOUAINANI: thi big problem is in +1 every time you will get time out , thanks for your time
j4at: yeah it should be x2<2 lol
j4at: TINOUAINANI
j4at: nvm its correct :3
j4at: THis is what happens when you don't test :
jacek: oO
TKirishima: Automaton2000
Automaton2000: this time i did it
TKirishima: Nice
aissvm: Nice
Remi.: Automaton2000 : turtle or not turtle ? that is the question
Automaton2000: i need to change the value
4kTre0912: Hola
Darleanow: j4at u online ?:)
waterproofsodium: i lost 2 CP :O
waterproofsodium: 2!!
waterproofsodium: that's 1 more than 1
mdfarhansadiq: hi
mdfarhansadiq: :grin:
waterproofsodium: hi
waterproofsodium: "sadiq"
waterproofsodium: I knew that was either indian or pakistan
mdfarhansadiq: Bangladesh
mdfarhansadiq: :D
waterproofsodium: oh bangladesh is its own
waterproofsodium: ignorant me
mdfarhansadiq: oh...no problem
waterproofsodium: is it still like
waterproofsodium: 50 degrees celsius there?
waterproofsodium: "in that region"
mdfarhansadiq: no...now it's 30 degrees
waterproofsodium: oh wow "lucky you"
mdfarhansadiq: :D
waterproofsodium: but it was like 40, wasn't it?
mdfarhansadiq: yeah...kind of...but it's like 27
mdfarhansadiq: now
waterproofsodium: feels like too early in the year
waterproofsodium: here it's already 30
mdfarhansadiq: o
waterproofsodium: but if we're lucky we stay below 35 most of the time
mdfarhansadiq: wow
waterproofsodium: anyways it gets crazy
waterproofsodium: once you go above body temperature sweating does no more help the body
mdfarhansadiq: exactly
waterproofsodium: I wish we wouldn't depend on "climate change just playing out" as we currently do lol
mdfarhansadiq: hahaha
mdfarhansadiq: sounds interesting
mdfarhansadiq: what's your real name?
mdfarhansadiq: :grin:
waterproofsodium: but what can you expect in an age where it's still ok for countries to attack other countries to acquire territory
waterproofsodium: oh I don't say my real name in here sorry
mdfarhansadiq: it's ok
mdfarhansadiq: i think if a matter can be solved by discussion then why do war
waterproofsodium: in this situation because the psychological disorders some people have can't be solved by discussion :p
mdfarhansadiq: yeah...maybe
mdfarhansadiq: we need a world where people are friendly and live peacefully
mdfarhansadiq: there is no arrogance, ego, hatred, fight
mdfarhansadiq: :relaxed:
weptdog: Im completely new to coding where should I start??
mdfarhansadiq: i think you can start from practice
mdfarhansadiq: by using practice option
mdfarhansadiq: https://www.codingame.com/training
Lisa-Has-Ideas: Welcome weptdog... careful, its addictive. :wink:
Lisa-Has-Ideas: Question for anyone: Why does the Clash of Code get referred to as "5 minute coding battles" but they really are 15 minutes ??
Ayza: probably because you are supposed to solve it in 5 minutes or so
waterproofsodium: Lisa-Has-Ideas
waterproofsodium: marketing
RandomSteve: it should theorically be posible to solve them in 5 minutes
RandomSteve: but you are given 15 to solve them
RandomSteve: but yes, it is a 15 minute battle
waterproofsodium: it's theoretically possible to solve each and everyone of them in < 1 min ig
RandomSteve: I highly doubt that
RandomSteve: some are very hard
waterproofsodium: i mean
waterproofsodium: "theoretically possible"
waterproofsodium: just taking you by your words
RandomSteve: All right my phrase was a bit open for interpretation but you know what I mean
waterproofsodium: a reasonable constraint for a theoretical limit might be typing speed of the world champion
RandomSteve: true
waterproofsodium: meaning you could theoretically solve most of them in 20 sec ;)
RandomSteve: a lot of them are solvable in that amount of time yes
waterproofsodium: I would go by what a experienced clasher does
waterproofsodium: and yeah most of them may be even solvable in 3 min
Lisa-Has-Ideas: ha, okay
Lisa-Has-Ideas: ha, okay
Lisa-Has-Ideas: ha, okay
RandomSteve: xd
Lisa-Has-Ideas: ha, okay
RandomSteve: all right you might wanna stop doing that I mean a mod might get mad
waterproofsodium: once is an accident
waterproofsodium: maybe 2
Lisa-Has-Ideas: Sorry... it was my computer. I thought it wasn't taking it. (Sorry)
waterproofsodium: three?
waterproofsodium: no that's a pattern :P
Lisa-Has-Ideas: Yeah, I'm dumb
waterproofsodium: (fav movie quote)
RandomSteve: I'm sure you're very smart Lisa
waterproofsodium: finding out it's not a movie quote
Lisa-Has-Ideas: (I didn't see all these wonderful responses to my question earlier either. Thank Ya!!)
RandomSteve: my pleasure
RandomSteve: No, I am your father
Lisa-Has-Ideas: It varies depending on what movie I just watched, but this is a good one: “This is the day you will always remember as the day you almost caught Captain Jack Sparrow”
RandomSteve: yeah that is a nice one
briankings: I have no idea what im doing
xiaoping: share code
xiaoping: i want to see
RandomSteve: me too
RandomSteve: How am I top 5% in this website if I started programming about two months ago? do 95% of people quit after two months?
RandomSteve: actually top 4% now!
LeJordy: maybe you just do it more often
RandomSteve: I guess it's something like that
RandomSteve: I am really happy with the progress I am making so far
RandomSteve: hello there
