I recently joined Codeforces and gave my 2nd contest (Codeforces Round #725 (Div. 3)) yesterday. None of my solutions got accepted, the only solution I submitted was showing the wrong answer on test 1, and after two round of judging, my rating has been increased by 216. This made me confused over how the rating system works here on Codeforces. Would anyone mind taking a moment to help me with this?
