Codeforces Alpha Round #20 (Codeforces format)
By MikeMirzayanov, 15 years ago, translation, In English

Hello!

Today will be the first alpha test of the new format of the competition. Registration will be limited - as soon as about 60 participants have register, I'll close it. Invited to participate, only those who have read rules draft. The document is in Russian, so I expect most participants from Russia. After some time we will translate the rules into English, and make this type of rounds really international.

In this round will be used folklore problems and the duration had to be reduced. For sure, it will be non-rated. Codeforces not guarantee that everything will work well - so be patient.

Many thanks to those who gathered to take part. I hope it will be interesting.

UPD 1. Contest duration changed to be 90 minutes.
UPD 2. In order to take part in contest, your browser should have installed flash player.
UPD 3. Contest will start on 19:30.

    Problems will be in Russian and English. You may try to use Google Translate to read the rules. In case of you can't understand it, just do not participate - it will not affect you rating (even if you will participate it will not affect rating too).

            I don't understand the rules (google translator failed to explain it to me :( )
            I saw there is minus point, is this sth like topcoder? So is it true that we can't know that our program got accepted during the contest(we must wait until challenge phase ended)?

I was 20 seconds away to hack adamax's solution. The case (in problem b) was a smaller than 0 and delta smaller than 0 or smth like that. I always seem to be a little late. The same 20 seconds were needed for me to send succesfully another problem at ACM ICPC Romania. AHhh!! I hate it :(
But it is always the first time I participated in such a contest(with hacks-I've never been in a topcoder SRM although I plan too- ) and I loved it!! Great job to the organizers. Sorry I don't speak russian.

    Replace int with long for the distance.

        I was solving that problem. Came across its thread. Saw that someone else too got WA for the same mistake I made and had asked about it just 11 days ago. So thought that it wouldn't hurt to point out their mistake and help them :)
