Alice and Bob are too smart so called coders.They have now figured out how to escape from Plagiarism. Mayank is struggling with with Plagiarism on codeforces now he wants to figure it out if his two friends Alice and Bob have applied the rule to avoid Plagiarism.

They can perform two type of operations.

1. Change the variable names to any other lowercase Latin letters.

2. Insert lot of commented code.

Sample test case:

Please Upvote if they followed the rule.

Note-I was wondering why the submission of same problem during contest of both players have not exceeded 10 minutes.

For more test cases open their respective profiles.

 » 17 months ago, # | ← Rev. 2 →   +2 Operation 2 can also be "Insert useless code" (eg. 95885430, 120064716).
 » 17 months ago, # |   +30 It's quite interesting that the author of this blog made so many fake accounts to comment on this blog..
•  » » 17 months ago, # ^ |   +1 to make peace we need to use violent methods sometime, i guess you got ur answer :)
•  » » » 17 months ago, # ^ |   +6 Feels so bad that you are liking your own comment from alt accounts...
•  » » » » 17 months ago, # ^ |   +3 Feels bad that you are still stuck at newbie due to these cheaters
•  » » » » » 17 months ago, # ^ |   +5 Not because of cheaters... its just because I did so many blunders in my previous contests....
 » 17 months ago, # |   +8 This is too much. At least pay some respect for problems A and B. You can do that by yourself.
•  » » 17 months ago, # ^ |   +14 If people start to solve A, B by own then the telegram solution selling market would die. Cuz cheaters are only able to solve those 2 problems in contest :holyfuck:
 » 17 months ago, # |   +18 What else can be expected from the college of twoseven.All these people cheating doing cp for job and spoiling it for the others
•  » » 17 months ago, # ^ | ← Rev. 2 →   0 Why does it matter to you if someone cheats? And you don't have the guts to comment from ur main account. I wonder why.
•  » » » 17 months ago, # ^ | ← Rev. 2 →   0 Well let's have a scenario you are playing your favorite game (CS GO) to relax. You queue into a match and start playing. The next thing you know someone is cheating and has spoiled at least that match for you. The cheater while cheating has wasted your time and due to this your interest in the game drops. Similar is the case with these cp cheaters.Edit: Just realized that the accused nitin_05 has changed his org name. What kind of morals does this person have . He has been accused and instead of removing his previous org name from account. He has put a new one in place , defaming the new org. My request to you nitin_05 , please remove the college name from yours codeforces id. If you want this to prevent people from getting to your linkedin ID just know that it's trash af and worth no one 's time.
•  » » » » 17 months ago, # ^ |   0 Well, csgo is entirely different scenario cuz in that I am directly affected. In codefoces, it doesn't matter to me if anyone is cheating, since it doesn't affect me in any way.
•  » » » » » 17 months ago, # ^ |   0 Cheating affects each and every participant of a contest. Just read about how rating mechanism works and you will know.
 » 17 months ago, # |   -6 I find it very suspicious that an alternative account was able to randomly identify such an Alice and Bob. Do you all go to the same school or something? Can you please keep the drama to yourselves? Yes, the plagiarism checker is kind of outdated, but that doesn't give you the right to openly attack each other (when calari could have posted links to code snippets, or cropped out photos instead of the submissions themselves)
•  » » 17 months ago, # ^ |   +2 You seem to be one of those. 1. No we don't go to same school. 2. You can also keep this drama to yourself. 3. who gave you the right to comment in this blog. And about alternate account, people from cheaters community keep on messaging wrong things and we can't report them.
•  » » » 17 months ago, # ^ |   0 obviously you did something that even computer can't do. But I was really wondering how a human can actually find out two exact same solution out of thousands contests and 1000s submissions. If we even do brute force it is quite hard for a human. themadprogramer's comment has point too.
•  » » » » 17 months ago, # ^ |   0 But I was really wondering how a human can actually find out two exact same solution out of thousands contests and 1000s submissions. Just repeatedly picking random pairs of contestants and taking a look at their solutions will eventually lead to discovering a pair of suspected cheaters: https://en.wikipedia.org/wiki/Infinite_monkey_theoremI'm not surprised to see such cheater discovery blogs popping up from time to time. But the main problem is that this method of searching for cheaters doesn't scale and can't catch them all, while wasting an enormous amount of man hours. The only positive aspect is that the cheaters can never feel safe even after fooling the automated plagiarism checker.
