I have given the previous div 2 contest very well and reached to pupil by that contest. But afterward ratings gone down to 1028 due to plagiarism check by system. It was due to coincidence that we both seem to have same code but it isn't. Yiu can check it.I have fairly given contest and with my hardwork I did well in contest. But due to this, my ratings gone down and I have been made fun I'm college which is not acceptable. Please look into this matter @codeforces and @Mikhail Mirzayanov. Please help me to get my ratings back
