First of all I wanna thanks contest organizer for their effort to make it REALLY a good competition ^_^.I would participate next year if I could ^_^

I wanna summarize my trip at VK cup ^_^.

On the first day I arrived at the hotel.I got very tired so I fall asleep >_<.

On the second day there's a AI-contest.It's very interesting!My Robot "DiaoSi"(In Chinese it means a man without money or luck or girlfriends or something) kill two cars in a shot in Round 1.It make me really excited.rudradevbasak's car impress me a lot.It seems just driven by human!

I'm a big fan of tourist,It's lucky for me to seems him in really world!(I fail in China National Team Selection Contest and has no chance to take part in IOI T_T).He's really handsome!

The contest problems is randomly-ordered and very interesting.

(It seems there'll be a online-version of this contest.So I will not talked about contest problems...)

I make a very silly mistake in Problem C.I use a.substr(at-3,at) to get the last 3 chars.But It should be a.substr(at-3,3) T_T..Fortunately I found it at the end of contest..But losing many points T_T.

s-quark take the lead for a long time.But sevenkplus overtook him by 2 successful challenges.At last tourist solve all the problems and take the lead.

But unfortunately tourist's A fail T_T.So sevenkplus take home 30,000. s-quark take home 20,000 $.They're my close friends ^_^.

sevenkplus is only 16-years old and will represent China for this year's IOI.I'm looking forward his nice results at IOI ^_^.

s-quark is also a very talented student.He's a little older than me and has celebrated his 17th birthday recently.He also make onsite in GCJ Round 3(rank 7-th,But he can't take part onsite round because age-limitation T_T).

Before ST I ranked 11-th,the first who don't have price T_T.But some people fail on some problem and I become 6-th after ST.take home 1000$ ^_^.

They also give a cool laptop computer to everyone.I can't wait to use it ^_^.

(-To be continued...It's late now T_T).
