Hello, I was trying to solve the problems from this competition, at the judge http://opentrains.snarknews.info/~ejudge. But I cannot solve a few problems and I cannot find any tutorial in English, and I do not know how to do the search for Russian solutions, do they exist? The problems are all very nice. If anybody knows solution to any one of them expect A,B, E J. (Div 1 only) I will be very happy. Thanks in advance!
