The X regional school team programming contest will be held in Saratov on Tuesday, 18 of October. The jury has prepared a set of interesting problems. We came to conclusion that it will be unfair if these tasks are available only for the onsite school teams. That's why we decided to organize a contest with these tasks on Codeforces.

The contest starts at 10.30 MSK (half an hour later than the start of the school contest: it is done to give the organizers some time to ensure that everything goes well) and will last 5 hours. The rules of the contest are official ACM ICPC rules. Both teams and individual participants are allowed to take part in it. For individuals the contest will be rated. Registration will be open until the end of the contest.

The contest was prepared by members of the best teams of the Saratov State University: Gerald Agapov, Polina Bondarenko, Ivan Fefer, Artem Rakhov, Nickolay Kuznetsov, Edvard Davtyan, Pavel Kholkin and Igor Kudryashov, as well as by our "veterans": Natalia Bondarenko, Michael Mirzayanov and me, Dmitry Matov. Maria Belova also did an excellent job and translated the statements into English. 

Enjoy the contest!

The statements will be available as PDF via links:

It will be file input-output in these problems. Read statements carefully.

Part 1

My further narration becomes less sequential and consistent than the first part. This is mostly due to the fact that competition rounds themselves are covered in the official blog (not to mention that I haven't followed all of them from start to finish), so I'll focus on the interesting things which were happening between the rounds, after them and sometimes even instead of them :-)

At the end of July TopCoder Studio ran a contest to get some ideas of how to entertain people at the onsites. The voting for the ideas had a very poor interface (I wonder whether there was a single person who has read all the ideas before voting?), but still it allowed to choose four ideas:

TCO11 - is the second (and hopefully not the last) finals I've visited as a blogger. I hope that not everybody here followed the official blog, and thus my story of this trip will be read as an original art work :-)

Day -1. Arrival


I arrived one day earlier than most of the finalists, on Friday evening local time. How does one do this? Long story short, you just don't rely on Barbara's choice, and (when filling travel info) write something like "I like this flight, and I'm in SWISS mileage program, and I absolutely love Zürich". Disclaimer: if everybody uses this hack, it might stop working, so beware.

Last time I mentioned, that one of the winners of the 'best event for participants' competition was a girl, who offered participants to take pictures based on tasks like "take a picture of yourself and <description of other person> doing <description of setting>". Even though that is a really awesome event, very few people were interested in it, which was very sad.

Every person had a different set of 10 tasks, the winner was the one who had more pictures, and the tiebreaker was an additional picture, having most people in the air jumping on the beach.
At the end I had only 9 pictures + a tiebreaker with 8 people in the air, while MikhaelOK had 10 pics without a tiebreaker. The person for the 10th picture already agreed to help me, but organizers told me that I do not qualify for the prize of 2012 trip (since I am one of the sponsors), and I just gave up.

My tasks were:
1. Take a picture with a TopCoder Admin with TCO logo in the background. Everybody had that one, and it was very easy.

TopCoder Open 2011 keeps going.

Yesterday we were supposed to hold a poker tournament with a grand prize MacBook Air. There were a lot of people willing to participate, which forced us to split the tournament into two elimination rounds and one final. Out of 16 people who registered for the tournament, 8 were russian-speaking, and all of them appeared to be in the same elimination round. Petr and MikhaelOK advanced from that round, while 7ania7 and theycallhimtom advanced from another one, which was non-russian-speaking. Unfortunately I don't have any pictures of the elimination rounds, however, we played more poker that day, in the same place, so this picture gives you pretty good understanding of how it looked like (during the elimination round it was a little bit more crowded though):


Last time I didn't publish any pictures of a hotel, except one view out of the window. The hotel is called The Westin Diplomat.


It is located in a Hollywood city. The city is in 20 minutes of driving from Miami, however it looks like a small village with a lot of palms. The hotel looks weird in such a setting, since essentially it is 36-storey skyscraper. It is located right next to the Ocean shore, such that the moment you leave the hotel, you find yourself on the beach.

Today I and Eric, CEO of MemSQL, went to Florida, to the Hollywood city, to visit TopCoder Open 2011, which we sponsor. Intel and Facebook are two other sponsors.
We left San Francisco at 8 AM. In SFO we saw Petr. That made us believe, that he moved to the Valley, which turned out not to be the case.
First thing you see in the hotel is TopCoder banner. Do you know the company, which is listed third in the sponsors list? :о


We went to a Ballroom, where we needed to install our booth. Intel has entire corner in the ballroom, while we and Facebook have small table and a screen. This is how it looks like:


When booth had been installed, we checked in to the room. According to what I heard from competitors, TopCoder provided them with rooms with no ocean view. Since we didn't have room provided by topcoder, for ourselves we got the one with the view.


In 2008, when I was visiting all the programming events, I was taking pictures of all the TopCoders, and other people, who were related to the community, with a stuffed pig. Some of those pictures you can find in my blog here. This time three more people didn't manage to avoid my camera. One of them is Ivan Metelsky, who is working on topcoder SRMs, and also is a judge on the TCO:

Two other are Artem Rakhov and Mike Mirzayanov, who are well known on this website :)

Hello!

Yesterday I got to the Hollywood (not in California, but in Florida). Then I came out from airport, I felt hot, humid air. Not forgotten feeling from the ACM-ICPC finals tried to fool my brain, that I was not leaving Florida.

I was flying with Misha Kever (which the handle here?). Artem Rakhov (RAD) appeared when I was asleep. It seems that he has arrived together with Sergey Rogulenko(SergeiRogulenko).

It turned out that the rainy season is not over. So here “cloudy, possible rain." I did not like the ocean — very warm, quite without the waves, it is necessary to overcome large distance to swim on depth.

By the way, I’m in the room #1760. It will be good to see in comments rooms of other finalists.

As they say, to be continued ...
