I just went through leader board of Div 2 and I was surprised to see almost 90 people having score 710.335 (Despite the fact that this time challenge problem was there).
So it decided to see submissions of few guys and I found many of them has almost same code.
Few examples are:
Check out submissions of rajan9353 , rajan0909, s_amardeep and adi_c0d3.
Dense graph submissions:
rajan9353’s submission
rajan0909’s submission
s_amardeep’s submission
adi_c0d3’s submission
If you see all these submissions carefully then you will find that these submissions either have template changed or variables changes.
Let us discuss about few legends in detail.
Firstly coming on s_amardeep. This guy has made his code unreadable by adding unnecessary code which is known as Code Obfuscation . His logic of code only lies between line 277 and line 316. Code from line 11 to line 276 is just useless.
Now coming to our ultra legend rajan9353 and rajan0909 . I also doubt these two id’s belong to same person because of these points:
- rajan9353’s submission and rajan0909’s submission have only two differences. If you delete rajan9353’s template (which is almost of 347 lines) , then you will find that these are exactly same (only variables are changed).
- Checkout another submission by rajan9353. This submission is same as that of rajan0909.
- Most obvious point both are named Rajan Arora and belong to same college.
I was not gonna write all these things but I was suprised and sad by seeing the amount of effort these guys are doing to cheat. Hope moss is strong enough to detect this plagiarism. Also @admin please take action for Code Obfuscation on rajan9353 and s_amardeep. And action of cheating on all of them.
