Hello fellow coders, I was thinking to write about this since many contests but finally I gave in after yesterday's starters on Codechef. I thought this to be an appropriate forum to discuss about this mass cheating that goes on every contest. Yesterday in DIV 2, the first 4 questions were POINTS AND LINES, EQUAL MEX, BUILDING TOWERS and the 4th one was K DISTINCT ARRAY. So although I was slow I was still able to solve 3 questions in about 35-40 minutes but then came 4th. I brain stormed a lot but I was unable to form a perfect solution but it was not a problem. I was good still trying when suddenly the submissions for 4th question started surging up and within span of 2 mins submission became from around 112 to nearly 450 and so it goes on. I was very upset by the fact that I was unable to do it and my rank worsened and my rank at the end of the contest was around 2200+ which is very bad and is the worst performance by me. So today I got up to check who had successfully did the 4th one. There were near about 1743 submissions and I started checking them and I was stunned, shocked and very angry. Consecutively I saw last 15-20 submissions which were just the exact same. In some there were even comments that were possibly written by the original writer of the solution like // plz change variable names. I'll attach them below but this ignited in me a feeling of betrayal as a good coder. Although Codechef has started plagiarising people but it makes no sense cause your rating increase or decrease is determined by your rank in contest which makes it absolutely useless cause I still will get downfall despite me solving it genuinely and some other random guy paying for solutions on telegram and getting AC. So cause of this reason I was totally shook and I now have 0 interest of giving a contest on codechef as its no longer a trust worthy platform and its just a matter of cheat and rise. I'll attach some link for everyone to see. No hard feelings for anyone but this should be seen Links : https://www.codechef.com/viewsolution/58141952 https://www.codechef.com/viewsolution/58141939 https://www.codechef.com/viewsolution/58141949 https://www.codechef.com/viewsolution/58141795 https://www.codechef.com/viewsolution/58141851 https://www.codechef.com/viewsolution/58141779 https://www.codechef.com/viewsolution/58141777 https://www.codechef.com/viewsolution/58141742 https://www.codechef.com/viewsolution/58141751 https://www.codechef.com/viewsolution/58141767 https://www.codechef.com/viewsolution/58139521
