Hi Codeforces,

BWC(Black.White Crow) Round #5 is going to take place on BWC At 6 PM this Friday.(Tehran Timezone).Problem statements are in Perisan.

This Contest will have 5 problems and each of them has some subtasks. Each subtask is a short answer algorithmic problem(Like Project Euler). The problems will be easy. Writer of the Round is me (ATofighi). I'd like to thank strange_voice for testing the Contest.

Good luck and Have fun.
