Could someone help me with this task. I have a solution but it is saying Runtime error. Could someone say why? Here is my code:
#include<stdio.h>
#include<algorithm>
using namespace std;
int d[2002][102][102];
int a[102][102],n,m;
main()
{
freopen("input.txt","r",stdin);freopen("output.txt","w",stdout);
int i,j,k,l,v;
scanf("%d%d",&n,&m);
for (i=1;i<=n;i++)
for (j=1;j<=n;j++)
scanf("%d",&a[i][j]);
d[0][0][1]=1;
for (l=1;l<=m;l++)
{
for (i=1;i<=n;i++)
{
for (j=1;j<=n;j++)
{
v=max(max(d[l-1][i-1][j],d[l-1][i+1][j]),max(d[l-1][i][j-1],d[l-1][i][j+1]));
if(v!=0)d[l][i][j]=v+a[i][j];
if(i==j&&l==1&&i==1)d[l][i][j]--;
if(l==m)
{
if(i==j&&i==1)
k=d[l][i][j];
k=max(k,d[l][i][j]);
}
}
}
}
printf("%d\n",k);
return 0;
}
