#include<stdio.h>

long  mx,Matrix[1010][1010],i,j,k,y,sum,dim;

int main()
{

while(scanf("%ld",&dim)==1)
{
mx=-99999;sum=0;
for(i=0;i<101;i++)
for(j=0;j<101;j++)
Matrix[i][j]=0;

for(i=1;i<=dim;i++)

for( j = 1 ; j <= dim ; j++)

{
scanf("%ld", &Matrix[i][j]);

Matrix[i][j]+= Matrix[i][j-1] + Matrix[i-1][j] - Matrix[i-1][j-1];

if(mx < Matrix[i][j])
mx = Matrix[i][j];
}

for(i = 1; i <= dim ; i++)

for(j = 1; j <= dim ; j++)

for( y = 1; y < i ; y++)

for( k = 1 ; k < j ; k++)

{
sum = Matrix[i][j] - Matrix[i][k-1] - Matrix[y-1][j] + Matrix[y-1][k-1];

if(mx < sum)
mx = sum;
sum = 0;
}
printf("%ld\n",mx);
}
return 0;
}
