Hi all! :)
I'm glad to invite you to participate in Codeforces Round #148 today. I (Hamed Valizadeh) am the author of this round.
Score distribution will be the standard 500-1000-1500-2000-2500 in both divisions.
Hope you find the problems interesting to solve.
Good luck and have fun ;)
Update. Contest is over. Congratulations to the winners of both divisions! :)
BTW, I hope you didn't get sick of that boring problem! :-"
Update 2. The editorial is ready now, sorry for the delay. http://codeforces.com/blog/entry/5765
