UEMCO question copied !

I just found that the second question of UEMCO https://www.codechef.com/UEMC2017/problems/UEMCOSA is copied directly from a hackerearth past contest https://www.hackerearth.com/problem/algorithm/last-ant-on-road/description/ .

Not sure if any other question is also copied. But this acts are really demotivating and takes away the fun of contests. :(

oh, and the 50k prize was a joke too, one of my friends at uem told me! (after i wasted my time in that contest)

prize money is a joke! That too on such an international online platform like CodeChef is really something quite unexpected. @admin please have a look into such matters. :/

@swetankmodi - Are you sure about the correctness of your claim? Because making a contest with no intention of giving prizes sounds like direct fraud to me if I put it bluntly.

@vijju123 I got the prize from UEMCO last week so I think my claim (based on facebook message from probably a fake account) was proved incorrect. They gave the prizes! (atleast can confirm I got it)

Not only this. The problems were poorly formatted, the I/O format wasn't available and also they weren't replying to the comments. My submission pretty much sums it up: https://www.codechef.com/viewsolution/16008313

Yes! The problem statements were not very clear. Even if the problems lacked explanations of the test cases, the doubts in the comment sections were unanswered. These things are very sad. :/

(30 Oct '17, 00:11) jaideeppyne5★

awful I/O format , this is what i can say!

(30 Oct '17, 00:37) striverlearner3★

I was doubting this throughout the contest when i saw the level of questions. A point might not sound good but that made me to doubt was that their college has a maximum of 4* rating profile. And the level of questions spoke something else at-least. By far the worst contest i took part in. :) , Might be the other questions are copied also , but tough to find out the questions as they changed the names and all.

Copying codechef's question in codechef itself XD. Pro level :P.

(30 Oct '17, 02:22) jaideeppyne5★

actually that is a SPOJ question. (question was posted in SPOJ before codechef)

(30 Oct '17, 22:20) swetankmodi ♦♦6★

Now a days it's common on codechef, in the past 2-3 months the contests organised by institutions had most of the questions copied from other platforms.

omg!!! was the prize a joke. Completely unexpected. I don't know about Plagiarism of questions but i can very surely say that the questions were very wrongly formulated(wrong language and many other errors). It was more of a mathematical patterns represented in form of questions to be coded rather than use of DS and algorithms. Proper error correction should be done before organizing a contest :(

Entire problem is same only the the names of characters have been changed. This is unfair. We were not able to put this as a new question due to lack of enough karma.

You always have the option to report this to mod via mail, OR use the thread which I exclusively put up so that you guys can ask questions.

According to codechef's guidelines, you can have copied questions in a closed contest.

I don't see any point in having all copied questions in an online long contest. They didn't even bother changing the stories. Many of them had the exact same Problem name too. A simple google search gives the original source.

@admin is taking action. Thank you :)

@abdullah768 - Copied questions are allowed only in clsoed contests, i.e. local contests limited to your college etc. Usually where you can make contestants devoid of google.

Thanks for reporting this. We are looking into it.

(18 Dec '17, 16:16) admin ♦♦0★

Oh my bad, I thought anything which wasn't there in the ongoing contest list was a closed one and were ignored by admin. Glad to be proven wrong :)

(18 Dec '17, 17:07) abdullah7686★

Thanks a lot @admin for the quick action. My faith in humanity is restored. Regards, The Dark Knight.

Are you sure that the rest 3 are not copied ? XD

(30 Oct '17, 02:24) jaideeppyne5★

2 are Pattern Finding. And I don't if the other problem is copied.

(30 Oct '17, 02:36) desik_14★

yupp pattern should never be given directly as they did, it can be easily found on oeis

(31 Oct '17, 11:15) rohit_08015★

This is very sad :( Codechef must take strict action to avoid such kind of fake events.
