Sir , I have been wrongfully charged with plagiarism. I have sent my evidences via mail to help@codechef.com containing pictures of my rough copy where I solved 3 of the contest questions. You can see it and the the time taken by me in solving those questions.
If I would have cheated there then I could have solved all 6 problems and in a very less time . Every question I have solved till now is with my own brain and hardwork not by copying some other’s code. I live in a remote district of maharashtra, from where will I copy when I am giving my contests outside the home as internet speed is very bad inside. I am surrounded by people who even don’t know how to use computer. And it’s very hard to handle both college and dsa practice but I am still handling it but it feels bad when such kind of problems happens even after putting much efforts so please see my evidences and remove these false plagiarism charges
It is hard to gain +33 rating in one contest and you have reduced 303 rating from my account in a single go . Please look at it

For LTIME104B , plz plag @aarindey
He has been doing cheating for a very long time .
Here are a few examples in LTIME104B
Problem :- PERMXORSUM
His solution
https://www.codechef.com/viewsolution/57365872
EXACTLY similar to these solutions,

  1. CodeChef: Practical coding for everyone
  2. CodeChef: Practical coding for everyone
  3. CodeChef: Practical coding for everyone
  4. CodeChef: Practical coding for everyone
  5. CodeChef: Practical coding for everyone
    And many more…

I didnt go further , I think 5 should be enough to proove my point .
All of them has the EXACT same code , some even have the same indentation . They have simply copied it from somewhere and pasted it here without knowing anything about the problem .

He has reached 4 stars by doing these things and then writing stupid posts on Linkedln.
