Codeforces round #299 is gonna take place soon(exact time) and I'm the writer. I'm lucky to be the first Iranian author in Codeforces, in your and our new year (2015 and 1394).
Now, I wanna thank: myself(PrinceOfPersia) for writing the problems(:P), MikeMirzayanov for great Codeforces and Polygon platform, Zlobober and DamonSalvatore and sobhan.miryoosefi for helping me prepare this round, Haghani and SoroushE for testing this round, Delinur for translating problem statements into Russian and big thanks to my great buddy, Swift for problem legends and the pictures.
Also, I wanna thank xiaodao for teaching me how to use polygon and testlib and so much other things about it (about a year ago).
This is my first official contest(after all those contests in Gym :D). I hope you enjoy it.
The main character of all problems is Tavas, well-known by eating CoffeeMix without water! Trust me, when he does that it smells awful.
Also, you'll meet his friends.
I hope you enjoy the problems. I wish you all high ratings, many Accepted solutions and Successful hacking attempts. And Hacked instead of Failed System Test.
Scoring will be posted later.
