It seems that problem 1A is very easy. But if the types of datum is int, you'll find that your answer can never be accepted, because the types of datum which the system inputs is long long. Here's the code.

#include<>													//the headfile
using namespace std;
int main(){
int n,m,a;												//define the datum
cin>>n>>m>>a;											//input the datum
