Hi, in the past few contests I have noticed that in some question few important points were not highlighted/bold. In those cases the participant sometimes tend to overlook the important details and assumptions that the question provides.
Let me cite a few examples.
In problem 1948C - Стрелочный путь, the part where its written that n is even is not properly highlighted. Other important details are highlighted, but they missed this part. I myself overlooked this information, which caused nothing but delay in solving and submission.
In problem 1933C - Количество значений k, the part where its written to find all distinct values of k, is also not highlighted.
Its my humble request to the problem authors, to please take care of these small details and make the experience to participate in contests smooth and pleasant.
