Subject: Test 3

1. How to read the updates files.
 FileInput updates = new FileInput("updates.txt");
	   String S;
	   while (!updates.eof()){
	     S = updates.getStringNoWhiteSpace();
	     int origin = updates.getInt();
	     int destination = updates.getInt();
	     int cost = updates.getInt();
	     System.out.println(S+" "+origin + " "+destination+" "+cost);

	   }

2. Use a *vector* of Edges(nodes) for your data structure. If you cannot
figure out how to do this, we will allow you to use an *array* of edges.
However there will be a 5 point deduction for this.

3. The test will be given during class period Monday and also Monday at
4:30 PM. Due to space limitations, I encourage you to take the test during
class period.

Let me know if you ahve any questions
