* @brief This program aims at calculating [nCr modulo p](https://cp-algorithms.com/combinatorics/binomial-coefficients.html).
* @details nCr is defined as n! / (r! * (n-r)!) where n! represents factorial
* of n. In many cases, the value of nCr is too large to fit in a 64 bit
* integer. Hence, in competitive programming, there are many problems or
