Chef is the new math prof in NITT. In his very first class, he taught binomial coefficients. Bongo is the topper of the class, and has a lot of ego for his solving skills. He kept on playing Ludo with his GirlFriend even in the class. After being caught, Chef asked him to solve a question to get the attendance for the subject. He defined the beta series beta(n,k) as n!/( k! * (n-k)!) , where n!= 1
