我的代码

#include <iostream>
using namespace std;
int main(int argc, char *argv[]) {
	int m,n,max=0,sum=0,i,j,maxi=0,num,sumdel,del;
	cin>>m>>n;
	for(i=0;i<m;i++)
	{
		cin>>num;
		sumdel=0;
		for(j=0;j<n;j++)
		{
			cin>>del;
			num+=del;
			sumdel-=del;
		}
		sum+=num;
		if(sumdel>max)
		{
			max=sumdel;
			maxi=i+1;
		}
	}
	cout<<sum<<" "<<maxi<<" "<<max;
	return 0;
}
