This month’s Long challenge on CodeChef JUNE 20 DIV 2 saw a sudden increase in the number of submissions(especially in DIV 2), resulting in increase of rankings, the major reasons were-
- The first few questions were very easy and hence that increased the number of correct submissions, this is not a big issue it’s the 2nd one.
- Plagiarism and Discussions during the contest
Because of this, the rankings were unfair to those who really did work hard . People discussed solutions, shared codes. This can be easily seen post-contest by reviewing submissions and how people managed to get correct answers to even the tougher problems of the contest in one attempt. There are groups on telegram who in the name of discussions are sharing codes during a live contest. Some people even took this to the next level by uploading solutions on YouTube during the contest, This is the solution of the 5th problem of Div2 which was on uploaded on June 13(Contest was live from 5 to 15 June) This is just one of the videos there are many other sources like these where plagiarism has happened. The long challenge seems to be a waste of time because even if you’re doing this contest with honesty, the rankings and hence ratings won’t be fair to you.
It’s very disheartening and unfair at the same time (especially for the beginners) that even after fairly participating in the contest, the results won’t be fair.
