I am still getting a Runtime Error. I always fill the StringBuffer like this and it always works so I guess it is something else. I have tried a lot of changes but I still get Runtime Error.

Still Runtime Error, even if did what you suggested :(


import java.util.*;
import java.io.*;

class Main
{
static TreeMap<String, Integer> map;
static Vector<Vector<Integer>> vect;
static int[] dist;
static Vector<String> names;
static Queue<Integer> q;

public static void main(String ...

Can you please see my code and tell me why I am getting Runtime Error ?

Can you give me some real test cases or show me why do I get a Runtime Error ?

Thanks.

Thanks a lot, I got Acc with Scanner.

But do the real tests have blanks inbetween or not ?

Thanks, I got Acc by using Scanner.

TO: lighted

Both tests work, but again Runtime Error.

TO: lighted Your test works for my code, it outputs 0. But I am getting a Runtime Error which is really strange.

Thanks anyway

Can someone help me by showing my mistake ? I am getting a Runtime Error !

Why do I get a runtime error ?

Nevermind, I got Acc by doing a topological sort and then a dfs to count the nr of components.

Why am I getting a runtime error ?
