#include<iostream>

using namespace std;

int main(){
  long long int n,m;
  while(cin >> n >> m){
    if(n>m)
      cout << m*(n+1) << endl;
else  

      cout << n*(m+1) << endl;
}
return 0;
}

Another Solution :

#include<iostream>
using namespace std;
int main(){
long long m, n;
cin >> n >> m;
if(m < n){
    long long s = n;
    n = m;
    m = s;
}
long long ans = 0;
ans = n * (m+1);

cout << ans << endl;
return 0;
}
