Three days ago there was a Div.2 with prize.It's my first time to take part in a contest with prize,so I don't know how to get it.I've also heard that the previous Codeton contest's prizes haven't been sent.I am wondering whether the Div.2's prizes haven't been sent or did I miss it.
Hi! As the author of the contest I can tell you that other people are in charge of distributing the prizes. After a while (I can't say exactly how long) the participants who are entitled to the prizes will be contacted (I assume with a system message on codeforces).
It will take around 4-5 months(even more) for the prize to reach you.
