Let's Welcome the Greatest Cheaters of the Universe (An Ultimate Cheaters Database)
By cheaters_database, 21 month(s) ago, In English

All of these cheaters are caught from the last codeforces round. Their submissions are 100% similar and here is the source of their cheating. Everyone got wrong answer on the test case 24 of problem D. Let's cry for 10 minutes for them xD. MikeMirzayanov please ban them from the round (possibly from codeforces). It will increase the rating of a lot of innocent coders in the last round. Also ban the downvoters (supporters of cheaters) of this post.

N.B. If there comes someone's name accidentally, please message me. I'll recheck the submission and remove the name if it seems a mistake.

    It's so amusing how so many Newbies solved D in a Div-2. Wow. I myself have never solved D in a live contest. I do know for sure that cheating will never give you knowledge, just a superficial number that is bound to get you banned.

I find it funny that literally if any of these cheaters used a mod_int template, they would’ve ACed and not been caught.

I guess that’s what happens when you copy code and change variables but don’t know that subtracting 1 requires a check on mod again. :P

    I think blocking their accounts would be enough. After all, people have spent a lot of time getting account ratings (especially experts and candidate masters), I doubt they will want to repeat this again.

      i think experts and candidate masters will not cheat as newbies,pupils,specialists do as they know what it takes to become expert and candidate master. also they will not be having much use of cheating as in majority cases only first three problems are getting leaked which they can be able to solve them easily.

      also no one gets banned directly they will get a warning for i guess three times after which account ban takes place , cheated and getting warned for three times and if even for the next time they get caught , they should defenitley get banned.

    In fact this is not caused by a weak pertest, these codes error when and only when the answer is calculated as 998244352. It is almost impossible for a tester to think that someone would make a mistake in such a stupid place, and it is harder to construct a hack test.

    1. find incomprehensible, exculpatory statements for cheaters

      getting WA on test 24 in Problem D, doesn't means like they are cheater.

    2. Open the content record

      https://codeforces.me/contest/1783/standings/participant/147453242#p147453242

    3. found to be a cheater

      https://codeforces.me/contest/1783/submission/188475497
    4. Leave satisfied.

    In fact, this person's identity was also falsified, and there is no Chinese word for the syllable 『kiu』. He is more likely to be one of the aforementioned cheaters alt.

            I don't know if you are a cheater,but as I know,your name is fake.

            • Your name is Yan Kiulan but none of Chinese words are pronounced with a 'kiu'.

            • I wonder why you write a fake name.Probably you are not Chinese.If you are,why not write your real name?If you think the name is your privacy,you can just leave it blank.

            • In OIerDB,that has data of every Chinese student who took part in any contest(we call OI in China),there is nobody has a name like YKL.(Searching result here).So you learn programming but never take part in any OI.That is really strange.

            • If you are Chinese,please tell us your Chinese name.

            • If you are a foreigner,don't sully China!!!

    I think you need to explain why you took at least 46 minutes to correctly solve problem A and only 4 minutes to successfully pass the pretests for problem D.

    Be aware that the difference in difficulty between the two questions is huge.

        I don't really understand why you would delete the original reply and re-post the exact same thing.

        But I think that if a contestant can pass the pretests for question D in one submission, they shouldn't be bothered by question A for so long and submit the wrong solution multiple times.

        And your behavior is so strange that maybe I should think you are writing answers to questions A, B, C, and D at the same time.

            Trying to solve problem A yourself does not show that there was no cheating on problem D.

            So no one cares if you solved problem A yourself, once you cheat on any question in a competition, you should be punished as you deserve.

        Even if your claim is true (which I don't believe one bit, but anyway), getting help from others is breaking the rules of a contest. Regardless of if you cheated or just got help from someone, you're not following contest rules.

        Well,bacause of the China's Great Firewall,we cannot watch because something on Youtube is politically sensitive in China.However,using VPN is a violation of criminal law.

        According to Article 12 of the Measures for the Security Protection of Computer Information Networks and International Internet, interconnection units, access units, legal persons or other organizations using computer information networks and international Internet shall, within 30 days from the date of official connection to the network, go to the receiving organ designated by the public security organ of the people's government of the province, autonomous region or municipality directly under the Central Government where they are located for filing procedures, and will access the units and users of this network The government of the People's Republic of China shall, within 30 days from the date of the official connection of the network, register the units and users of the network and report any changes to the units and users in a timely manner. The VPN is not illegal in China and in principle is not punishable, but it must be built by the relevant units and registered for the record, private construction of VPN or even the manufacture and sale of VPN may be suspected of illegal crime.

A warning can be given by the public security authorities, and if there is illegal income, the illegal income will be confiscated, and a fine of up to five thousand dollars can be imposed on the individual, and a fine of up to fifteen thousand dollars can be imposed on the unit, and if the circumstances are serious, and a penalty of stopping the network, connecting and shutting down for rectification within six months can be imposed, and if necessary, the operating license can be revoked or the networking qualification can be cancelled.

        There's a lot result on the Internet.You will be held seriously responsible and severely punished by the Chinese government as long as you watch Youtube in China.

        For me,I'm in Yunnan Province which is near the borders(only half a day's drive).So I sometimes go to Laos to watch Youtube on holidays.

I actually don't know why my name is here, my account is real. As for the justification that cheaters did blindly copy code and did not realise that modulo could become negative after subtracting a number. I did put ans%=mod in my submission to bring that back to (0,mod-1). But I did not know that (-ve)%(+ve) returns (-ve) until I looked up this after the contest. Had I copied blindly, I would not be able to debug and submit the correct code just after the contest (check 191607860).

Secondly, cheaters either copy almost the exact same code or sometimes add too many comments and spaces to make it difficult to detect. Please check that none of such measures were used.

Please check before adding names

    Ok, please explain the meaning of your x variable. I think you always have a reason to write it down, right?

      Yes sure, instead of storing the values in a an array and then computing the sum from 1 to cnt, it would be more space efficient to compute the sum when dp[i] comes from previous dp[i+1] (I have considered the array to be dp[]) there itself, so that we need not store previous values (dp[i+2], dp[i+3]... till end... I say previous because of reverse loop). That is why I used a variable (name x is the most common name I use after a and b) because it was possible to reduce storage of unncessary values.

          If F(i) is the expected no of moves when the hamming distance between a and b is i, then my dp[i] would be F(i)-F(i-1), where dp[] is the array I mentioned in the comment before.

          This is the recursion that I got dp[i]=(n/i-1)*dp[i+1]+(n/i) and F(0)=0.

    To prove that the solution idea is yours, show me your paperworks of equation of the solution. Can you explain your approach in short? Can you tell the initial equation of the expected number of moves for the problem?

      This is the link to the .pdf file which I have made by clicking photographs of my notebook.

      The only difference is that in this solution I added from i=2 to cnt at the end and added F(1) instead of adding from i=1 to cnt and adding F(0).

      Actually my start expression was pretty similar to the official editorial (which should be as they express the same function), but I rearranged it in forms of difference and it simplified the expression easily. (I mean instead of a_n in terms of both a_(n-1) and a_(n+1), we got just a_n in terms of a_(n+1))

Check my solution once and then include my name and secondly look the journey of the each coders and contest graphs that is always increasing max time and in minimum times they have reached good rating . It doesn't mean they have cheated. The concept of the question everybody had solved in the similar way taking a arbuitary number. Think and see before adding names and remove my name ASAP.

    First of all, great work! How did you collect all those? What script did you use? Also on what basis, do you remove names? They can makeup stories just to get their names removed. I think an appeal that leads to name removal should be public to the whole community not a private message. You can easily remove a friend for ex?

    Out of context. Why comment? The people you mentioned are in an older round and were already punished. This blog addresses #848 problem D string revisit. Same WA 24 solutions and it can never be a coincidence because it is the same modulo arithmetic logic error and same logic for the inv array.

To author, please add chromate00 to this list! Just take a look at his solution: 191601141 — it is the same as all the cheaters' ones, but he tried to make his cheating less obvious by changing small details!!

And the worst part is — he got Accepted despite having cheated!!!

This is because he just fixed the obvious bug — see https://codeforces.me/blog/entry/112147?#comment-999307 — it is still obvious from his submission that he cheated. His submission should be flagged!!!

            So just tell me why just changing a variable name got your solution from skipped verdict to accepted. Its because intially you copied it from somewhere and online judge matched it with some other solution and just by changing a variable name (r to q) it got accepted.

            In your response (https://codeforces.me/blog/entry/112147?#comment-999157), you said that your solution is similar to others' because everyone will get "a similar (if not same) solution to that task".

            So, I ask that you find a handful — just a handful — of top competitors (who are much less likely to cheat) that have such the same solution as yours. That should easy if what you're saying is correct, right?

            However, I think you will find that it isn't. But you are right in some respect; I can find hundreds upon hundreds of submissions that are extremely similar to yours — THE ONES WRITTEN BY CHEATERS IN THIS BLOG!

            I cannot find a single submission from the first few pages of standings that are as strikingly similar to yours as ANY of the ones in this blog exposing cheaters.

            Do you really still deny that you cheated? Do you really deny the resemblance between your submission and those of the cheaters?

            I know you will likely ignore this as always, and I will be downvoted by your alts and/or other cheaters (but to other cheaters — are you not annoyed that he got AC and you didn't? XD).

                I asked you explicitly to find a submission from one of the top competitors and explicitly stated my reasons for doing so.

                But you have provided a submission that clearly does not satisfy that, which tells me enough. Would you like to try again?

                For real dude, how on earth can you still deny it lol, there are 400 submissions here identical to yours and not one similar submission among the top competitors bruh.

      Wow. So he has cheated before — meaning this is "repeated cheating".

      In chromate00's own words, (https://codeforces.me/blog/entry/107339?#comment-956714) "repeated cheating leads to a ban".

      Should his account not be banned then?

        CF should ban anyone who has cheated even once.
        Once you cheat and are not punished, its highly likely you will cheat again.

          I agree, but there should be system for appealing bans because I personally would be worried about slight chance of coinciding with someone else's solution. (Probably 1 in a 100000 chance), but it most likely will happen to a person or two.

    I looked over the submissions. Most of them used linear mod inverse array as a pre-computation and then failed at test 24 since they output -1 (as no account for negative results when taking mod)

    While chromate code, looks to use fast power algorithm with mod according to Fermat theorem. and didn't fall on 24, accounted for negative result and put the mods correctly while looping from n to 2

    UPD: With more wise look over the code, I think it is a close call and xnudem may really have a point as the equation used at last is exactly as the cheaters' code and some other few similarities + correcting the -1 case

MD_DM, noob_coder_------- ------------- Some cheaters who get skip, but these two people Kaitoo and Adel_Mahmoud are really great at circumventing the system in Code Forces, one of them helps the other, and both codes are very similar, and that in some solutions you find that one of them puts the whole solution in one line ??? solutions in one line ? :- 181982089 && 187323042,

Kaitoo in TypeDB Forces 2023 (Div. 1 + Div. 2, Rated, Prizes!) he solved c and is similar to noob_coder_ , 191151542 , 191155612 and he didn't get skip, so I ask you Kaitoo why any one change dp to r ?? of cores to avoid get a skip ,

Similar solutions :-190390803 190401955

look the journey of the each one cheaters contest graph is always increasing max time and in minimum times they have reached good rating .

    to be honest, i thought this ques would and should be rated higher than 1600, because it was not just about dp, but also about selecting the optimal values, but many cheaters got the code online during the contest, i know some of the people who have never even used iterative dp in any ques, solve it using iterative dp during the contest, so the number of submissions affected the rating i believe.
