Massive Plagiarism happening in recent Google Kickstart Rounds.

Cheating Happens in every CP Competition. Obviously, It can't be Controlled but what can be done running a plagiarism check and removing Cheaters from the ranklist. Google can't even run a Plag Checker for such a prestigious Competition. What is the point of giving such Competitions? They should either do a plagiarism check or should remove these lines from rules of google kickstart.

(E) Sharing or using from others any information about a problem (including its content or solution) before the end of a round unless expressly permitted by the applicable Rules or these Terms

I mailed them about Round C two months ago and they replied back "If we see evidence of cheating or unfair play, participants are disqualified. The results published on our site and scoreboards are now final. We also can't release any information about other competitors." I even doubt that they didn't read my mail properly. Okay, Round C submissions were strange but I didn't have full proofs. So, I let that thing go.

Round D plagiarism-

I have full proof for Round D. Many of solutions were circulated in this telegram group. This Person 1 and This Person 2 has submitted the same solutions that were posted in telegram group while the contest was live. Just Check the solutions once. Now ranklist has been finalized and no action taken against him. Why?? This is unfair for those who participate fairly. I’m also attaching the screenshots below.

Proofs -

The solutions are exactly same. (Even the name of variables are same.)

Check Solutions of both the accounts. All 4 AC solutions are same. There will be many more but I found these two- https://codingcompetitions.withgoogle.com/kickstart/submissions/000000000019ff08/SGFyc2hpdDU2NA https://codingcompetitions.withgoogle.com/kickstart/submissions/000000000019ff08/U2lkZGhhbnRfS2hhcmU

Round C plagiarism-

Check submissions of [this guy](https://codingcompetitions.withgoogle.com/kickstart/submissions/000000000019ff43/SGFyc2hpdDU2NA. The submissions of this guy are really suspicious. He submitted all his programs in around last 30 minutes. Why would any person do that? Let's talk about Countdown problem first. He made his first and second submission this problem at times 02:23:04 and 02:25:33 respectively. He used the variable 'testcases' for these submissions and these were WA. At 02:27:08 (just after a minute and a half), he submitted another solution which was totally different from first two submissions. He used variable 't' for this submission and even whole code changed. No sane person would change the name of variable if his ans is wrong.

Now, for Stable Wall, he submitted a solution in C++ at 02:27:39 which was a WA. At 02:46:49 and 02:57:56, he submitted two solutions in java (one was WA and other AC) and these two java codes are very much different. Similarly, He used three languages in Perfect Subarray problem with gap of very less minutes.

Finally for Candies, He submitted C++ code at 2:34:04 and a python3 code at 2:35:58 . Either he is so fast that he just prepared a python3 program in less than 2 minutes or he already knew c++ would give TLE, so he had prepared the python3 code in advance (just in case C++ doesn’t work). He surely have got codes from someone else. These strange things show that he must have got codes from different persons and have tried them all. Now this was not enough as proof to Google

Now does Google have any answers to above proofs? I mailed about Round D yesterday and got no response till now. Are there any Codeforces users who have good connection there and float this to them? So they disqualify cheaters from Ranklist. I am tagging people whom I think have connections with google. Petr I_love_Tanya_Romanova jonathanirvings born2rule Anushi1998
