Tomorrow, at 9 pm, there is a rated contest named DCODE on codechef. Also, as there is cf round at 8:05 pm, it clashes with the timing. So with due respect, I just want to say that, ditch codechef because codechef is not at all worthy of holding a good contest. Be it lunchtime, be it ICPC, they ruined it all. So happy coding and hope you all achieve high rating(on codeforces, because that matters)
