#include <iostream>
using namespace std;
int main()
{   long long n,m,z,c,sum=0,count1=0,count2=0;
    cin>>n>>m;
   for(long long i=1;i<=n;i++) 
{
   count1+=i;}
  
   for(long long t=1;t<=m;t++) 
 {
  count2+=t;}
   
  int a=count1*count2;

  while(n!=0&&m!=0)
    {z=n*m;
    n--;
    m--;
    sum=sum+z;
	}
  c=a-sum;
  cout<<sum<<" "<<c<<endl;
  

	return 0;  
}

因为错了啊

int a数据溢出了，改成longlong就好了
