#include<iostream>
using namespace std;


int max1(int x,int y)
{   
	int max;
	if(x>1)
	max=max1(x-1,y-1);
	else
	max=max3(1,N-M+1);
	for(i=x;i<y;i++)
		if(max<max1(x,i))
			max=max1(x,i);
		return (max+m[x][y]);
}
int max2(int r,int s)
{
	int max;
	max=max1(r,s);
	for(int j=s-1;j>>r;j--)
		if(max<max1(r,j))
			max=max1(r,j);
		return max;
}
int max3(int e,int f)
{
	int max;
	max=m[e][M-N+1];
	for(i=1;i<M-N+1;i++)
		if(m[e][i]>max)
			max=m[e][i];
		return max;
}

int main()
{int result;

int M,N;
int m[4][6];
	cin>>M>>N>>endl;
	for(int i=1;i<M;i++)
	{
		for(int j=1;j<N;j++)
			cin>>m[i][j];

	}

result=max2(M,N);

return 0;
}
