Once on the border of two neighboring states, Customs officers stopped the programmer Vanu. He immediately caused them suspicion: he was constantly going there through the building of the customs, strangely looking at the sides and as if he had something in his mind. So I decided to do a full inspection. He was, of course, scared, said he was late and therefore so worried, but the customs officers did not listen to him, and they did the right thing. Ivan P. with the underground nickname Shebutny, was found 3 bags with various narcotic drugs, which there was not! In the bags, the drugs were distributed very correctly and none of them were repeated, with no more than 10 types of drugs in each bag. For the examination, the customs officers had to give exactly N types of narcotic drugs from each bag. The question arose before them: which drugs to give for examination, and which to destroy. Lieutenant Victor said that you need to look at all the possible options and choose from them, for which the officer Anton said that there may be too many options. Then they told Van that his conditions in prison would be much better if he helped them and calculated how many options to choose drugs. Vanya is a programmer, and he can only write programs, and his laptop was confiscated, so he asked you to help him. It is necessary to calculate how many different options you can choose the required set of drugs for the examination.
