What does (Div. 2 or Div. 3) mean？
Maybe it is just I'm new :D
Why it uses "or" instead of "and" ?
Recently some people always downvote my comments without any reason.
Sometimes I only ask a question, or gives some advice, but then I got a lot of downvote!
Not only me, but also many users are facing this problem.
What's the reason? Can anyone give me some suggestions?
Thank you very much.
This robot vjudge4 submited this problem almost one day later than me,but why he judged earlier than me?
Isn't it judged by submission time?
I want to get an answer,thx.
Thx llbra9z for answering this question.
Sorry for my bad English:D
