#include<stdio.h>

int main(){

int n,m;

while(scanf("%d %d",&n,&m)!=EOF){

int food[n][n];

int x1,x2,y1,y2,c;

for(int i=1;i<=n;i++){

for(int j=1;j<=n;j++){

scanf("%d",&food[i][j]);

}

}

for(int j=0;j<m;j++){

c=0; 

scanf("%d %d %d %d",&x1,&y1,&x2,&y2);

while(1){

if(x1>x2 || (x1==x2 && y1>y2)){

break;

}

c+=food[x1][y1];

y1++;

if(y1>n){

y1=1;

x1++;

}

}

printf("%d\n",c);

}

}

} 想問RE原因
