My solutions of Hackerrank Python Domain challenges. Since , so if the number of group is even, then the result is just facts[n % p] % p, otherwise is -facts[n % p] % p, which is equivelent to (p - facts[n % p]) % p.. And then we can express , calculate , and .Then if , must be zero mod P, otherwise, the result should be a1 * modinv (a2 * a3, P) where modinv is the modulo inverse function.
