Hi everybody! Two days later, in 19:35 held Codeforces Round #339 (Div. 1 & Div. 2) This round is unusual in that we, its authors, — usual schoolboys, involved with courses in school 179. For us its round — first experience and we tried to make it very interesting and unmistakable. I invite all of you write this round, because all problems are solved, but even tourist will think over some :)
Looking forward to seeing you!
