Clarifications

• The method getCost returns the cost of the directed edge that exist between startVertex and endVertex. You can assume that endVertex is adjacent to startVertex. Notice this method is NOT computing the cost between any two vertices. For this method ignore the @throws IllegalArgumentException information provided in the javadoc.



• If your project #8 does not compile in the submit server but works in Eclipse

     If you see an error message in the submit server mentioning 
     "Clover was unable to instrument ..." it could be because you are
     defining a class without fully providing the type.  For example:
  
     Stack<String> stack = new Stack<>();
  
     could work in Eclipse but it may fail in the submit server.  Use instead:
  
     Stack<String> stack = new Stack<String>();
    

• If your doDepthFirstSearch and doBreadthFirstSearch methods work in Eclipse, but not in the submit server, your problem might be that you are defining the callback parameter as PrintCallBack instead of Callback. The submit server expects Callback.
