It is very pathetic to see that some questions haven’t been framed properly and need clarifications , but when questions regarding clarifications are asked , the questions are deleted without giving reasons for so , why do you people add such kind of vague questions ?


Have you even asked your doubt in comment section ? A big NO!
Problem description is unambiguous and complete.
Is this discussion forum is a place to discuss a problem from live contest ?


calm down bro ,
well, ambiguity of problem should be decided by the solvers coz every problem creator will obiously defend himself. I never asked for discussing problems but rather clarifications , which problem settlers seemed to forget . Regarding comment section , from past two challenges , I have been posting in comments sections , but responses from problem settlers forced me to drag myself here.

I expect you people to test our coding logics but only after giving proper information .


I believe we have provided you enough information and complete description of a problem.
Before posting anything about live contest here, at least you should ask your doubt in comment section.
Well, once you solve the problem, you’ll understand everything.

Hi @harshraj22

Before starting my argument I hope you are a man of enough general sense to understand that your posts gets deleted if it seriously violates discussion rules.

The setter verified that you did NOT ask in comments for clarification and posted at discuss, which is NOT a place to discuss such things. Further, I did not find your doubt genuine either.

Please abide by spirit of contest - the penalties elsewise are firm and irrevocable.

hello @vijju123, discussion is already over . Please don’t try to restart it . As far as asking in comments is concerned , I guess you didn’t read my early comments where I clearly stated the reason . As far as finding doubts genuine is concerned , it depends on people to people ,no comments on that. And please stop terorising people by showing your power for penalties and other stuff …



As far as this forum is concerned anything related to the ongoing contest is strictly not allowed here.
Nobody here on the forum gives an f*ck whether you were able to solve question during the contest or not. Whether your doubts were resolved or not.
Anything thing related to the ongoing contest will be straight away deleted. Whether it’s genuine or not. Comments is place to ask such doubts. And whether you got reply over there or not is none of this forums business.
please stop terorising people by showing your power for penalties and other stuff ...........
please stop asking anything related to the ongoing contest by showing your power of asking questions and other stuff …

You can post questions regarding any clarification in the problem statement. However, please read the problem statements multiple times before posting your query. We take great care in trying to come up with unambiguous problem statements and most of the times it has been found the query asked is answered by a careful reading of the problem statement.
For further reading - What kind of comment should I post on the problem page?

I support @akil_av17
The question is complete and unambiguous(I am solver)…
Also @akil_av17 is very responsive to comments… It’s your fault if you don’t try asking the question in comment section first…
I would have understood your point if no one replied to you in comment section for a day when your question was relevant…
Also I liked the problem statement of @akil_av17… I believe it will improve my understanding skills if I try solving such questions…

@harshraj22 -

As far as asking in comments is concerned , I guess you didn't read my early comments where I clearly stated the reason .

Your reason was insufficient.

As far as finding doubts genuine is concerned , it depends on people to people ,no comments on that.

Please fix your thinking here. Things go by standards and by rules here, and not based on what any random user thinks. Rules are rules and are objective, independent of your “thinking”.

Its an easy decision, I find your thread against rules, I deleted it. :slight_smile:

@mgch you were right. Now, I can say that February long challenge is easy :stuck_out_tongue:

Tears in my eyes.

I had performed miserably in long challenges when I started cp. Now,all dots are getting connected ! I will always remember this Long Challenge as the one which made me reach Div.-‘1’ for the very first time.

Excellent Chef <3

Excellent Problems <3 <3

Thankyou for all the contribution, Codechef community :slight_smile:


Will it be an editorial for the challenge ( CHORCKIT ) ?


In previous long challenges Top 20 performers in global and Indian category used to get laddus .Is it reduced to 10 this time?? and if an Indian ranks within top 10 in both Global and Indian category then how will the laddu be distributed in the Indian category .

I think its 20. They just copy paste Cook-Off announcement.

Its confusing and more confusing as I ranked 11 in India

I’m no 10 :stuck_out_tongue:
If you don’t get laddus in <2 months. Bump a post here :stuck_out_tongue:

Mailed them for clarification. Hoping for a reply
