Hello programmers ! I think Codeforces authority should do something about identifying cheaters during contests. In today’s Div 4 contest I saw some of the contestant’s solutions to various problems (Specially D and F) after the contests . But surprisingly their solution is nearly the same, the logic and syntax also. I observed some of them modify other’s solutions by changing variable names, adding unnecessary comments, adding unnecessary functions etc. in this regards codeforces authority should implement the plagiarism check mechanism otherwise it is quite disappointing that someone who cheat on contests gain high rank rather than the trustworthy and ethical users. Thank You.
Can you kindly provide those submission links?
They are my friends. It's quite disappointing for me to expose them in front of everyone. As a friend it hurts me a lot. This blog post is just a reflection of my frustration and to take the attention of codeforces authority to prevent plagiarism. If any of the CF authorities ask for those links I will send them privately.
Maybe they have a joy of high rating, and You have Your joy of being able to comprehend puzzles of different complexity. After a contest, you look at jiangly's code... Did he solve it the way You did? Why he prefered this method, style? Is it more prefereble — no ! — this time your code is less cumbersome has a faster complexity and uses constant memory!!! Those are the questions that worries You. Isn't it a good place where everyone is happy? Why do you want to ruin it? Are you a police? There is no victim but you see there a crime. You want an order or a prison? You do.
bro u have solved a hell lot of problems and still you're struggling between newbie and pupil. Should i stop right now?
Half of the problems he has solved are rated below 1000. He's around the rating that is expected from someone on solving 800 1000 rated problems. Remember, Quality > Quantity. You can do like 2 hard problems a day and see more improvement than solving 50 800 rated problems a day.
