@sid_gup compare it with others, it have similar logic. I think he first saw this code and copied some part and modified others so that he canāt get caught. Since, itās have the same complexity as others have and it lies between the time range 1.82 to 1.92 where all the solutions are copied one thatās why i put it here.
And now itās upto admin whether they conisder it plagiarism or not.
@sobhagya, the last solution uses HopcroftKarp matching algorithm which is different from all the other solutions.
@karan173 and @sid_gup, i removed the last one and @karan173 from next time onwards, check twice your visiblity while you use ideone
@sobhagya: Your last to last comment makes a serious accusation. I know cheating in algorithmic coding in any contest pisses you off, but still it would be better not to see everyone through the same glasses.
@sid_gup and @karan173: Thanks for coming to my rescue.
Great work man. Hopefully people will stop cheating after few persons are punished for such acts.
you have copied the entire code to get AC and you say its not intentional. Who are you kidding dude. What about all those who have spent hours debugging their codes to get it right. This is a contest at least show some spirit.
The same thing happened to me in July Long when my ideone account got logged out automatically for two days and all submissions made during that time became public. I reported the cheating cases myself just after three hours the contest ended. Still my account was banned for more than two weeks and my rating took a significant drop. Codechef is very serious about these cheating cases. What is more disheartening is that two of these users are from our batch.
@admin @n2n_ and @all, for the above 4 solution categorizedā¦We apologize for such behaviorā¦When our individual solution got AC to WAā¦we had a day in our hand and so we coded together only for this question as we all have done different number of questions o n the contest, also we have not copied from IDEONE or other resourcesā¦Its not an excuse and we know that it is unacceptable behavior and we are ready to face penalties for the sameā¦We promise not to do the same in futureā¦
@admin I really apologize for submitting the same code .Actually we all 4 had coded together as a team as it was the last day of contest and all our solutions were giving wa so we submitted the same code .
I accept that this is my mistake and I assure you that it will not happen again in future ā¦
Hall of shame! That feels like a good idea!
@admin I want to register my serious apology on this matter.We were trying the code for all 10 days,even i got AC on the first day but due to re-evaluation of the code I got WA.Since,then I was trying to correct myself.On the last day of the contest,finally we decided to give a joint effort to it and due to the lack of time we all submitted the same code.
I know itās against the normsā¦may be our frustation lead us do such a shameful jobā¦I am guilty for what I have doneā¦and ready to face the consequencesā¦and I assure you I wonāt indulge in these activities in the future.
I Apologize to all.
Hall of shame is great idea and I think, that also note in profile (something like this ācoder cheatedā) is great, because such coder will never share his profile as his achievement 
In such case no rating decrease for such users is needed from my point of viewā¦
@tijoforyou yes. Actually, i checked some solution and i find them quite similar and their time range lies around 1.87. So, all i have to do is to check java solutions which lies just above and below that range. And seriously, all java codes between 1.82 to 1.92 are copied ones.
@svm11 I donāt want to hurt anyoneās feeling and itās not my intention here. I simply point out some wrong doing in the current contest. And as i already state your solution lies in the time range where all the solutions are copied one. Thatās why i put your name here. But, now i realises your code is genuine. So, i removed it.
And, itās not pisses me off that someone copied otherās code for rating or ranking. Now, i donāt care about it. Because in real world these things donāt matter.
Why giving second chance? Because: āWe know you cheated, you have to cheat better in next contest.ā? If they want, they can always create new account and start from the beginningā¦
ā¦or even better, update their name in DB to something like āusername (cheater)ā, then you can see it in all ratings tooā¦
These are exactly same and from Long contests NOV12 dammit ā¦ the copy thing goes so behind

They are exactly same and word to wordā¦
