I saw a account name similar to yours, infact all details were similar except username had extra a.
Submissions time were also quite similar, that too,only for june challenge. No previous participation. Do you know about it?

So true. I saw the same. Almost every other guy I know partially solved GUESSG in some way.
It’s not all sudden people were working from start. If you see there were only 3 problems that need to work on. Guess and Tuple were the one which need’s just observation and implementation. So until someone solves Delicious cakes no one could predict rank, in my case also in last 3 days i scored 160 point where 75 on Guess was on today morning 5 am. But i was was working day and night for 10 days. So it was not sudden.

Yeah it’s infact there is one in my college ranking i don’t know him personaly, but there is one person with same name, just adding 23 atlast of his name.
How come your ttuple solution for 10 and 100 has a day night difference ?? Also can you explain the approach you used for CONTAIN problem ?

There are several reasons for doing so in my opinion.
One of them is they don’t get time during whole week to solve it and hence they solve on Sunday or in the night after Sunday. People think about solutions whole week and finally implement when they get time.
Another can be they don’t want people to think that the question is easy. They don’t submit till end and other people feel like it’s a tough question. And then submit on the last day.

I agree, for many working professionals Sunday is the last day of long challenge and I’ve seen many of them chalking out some time on a Sunday evening to solve problems. So, it is not that they are copying someone’s solutions, it is just they didn’t get time the whole week

you can search for how to find convex hull peeling depth!
basically:
START
POPULATE THE PLANE WITH ALL POINTS
GENERATE CONVEX HULL
CHECK QUERY IS IN OR OUT
IF YES,
COUNT++
DELETE THE POINT THAT ARE IN THE CONVEX HULL
CONTINUE GENERATING CONVEX HULL AND CHECKING QUERY
IF NO
PRINT++
EXIT
I consider myself lucky i stumbled upon the zero wale edge cases! that changed everything for me!
It’s same as yours, maann21.
I searched for CodeChef: Practical coding for everyone but it doesn’t exist.
but if you find something like my username do tell me! thanks!
Yup sure.

Or cheating happens here
same thing
i think codechef should ban the discussion during long contest on some social media platform like fb ,telegram etc but it is nearly impossible to ban all those things.
so we are left with below given options to deal with plagiarism:-
-
Divide the long contest into 10 days and only some questions should be given for limited number of hours and combing all the points of those 10 days codechef will allot rating and ranks.( its like conducting codechef lunchtime daily for ten days and giving combined result)
-
Make long contest unrated (i am so sorry for writing this , i know you all will become angry after reading this . please forgive me . but honest students like you all are losing here because of plagiarism)
3)Admin should do something to avoid plagiarism.
I think this is a problem given by students (we can say created by students) to codechef to solve and lets see whether codechef will get AC or not.
thank you if you are reading this and sorry for my bad english.
Its so saddening that people really cheat. I know who have copied code and from whom, here I am with my low rank meanwhile that person participated in first contest and boom solved tricky question just few hours before contest ended. But what can be done. Long challenges are awesome and should remain rated but people who cheat are doing very wrong.
