Follow-up Question

Your Question:

While your code does work, there is the problem of the constraints put on us for this project. I will paste them from the instructions document.

Constraints

• You may not construct any arrays, ArrayLists, LinkedLists, Stacks, Queues, or other data

structures; you must use list nodes. You may not modify the list of Strings passed to your constructor.

• If there are n names in the list of Strings passed to your constructor, you should create exactly n new AssassinNode objects in your constructor. As people are killed, you have to move their node from the kill ring to the graveyard by changing references, without creating any new node objects.

• Your constructor will create the initial kill ring of nodes, and then your class may not create any more nodes for the rest of the program. You are allowed to declare as many local variables of type AssassinNode (like current from lecture) as you like. AssassinNode variables are not node objects and therefore don’t count against the limit of n nodes. You should write some of your own testing code. AssassinMain requires every method to be written in order to compile, and it never generates any of the exceptions you have to handle, so it is not exhaustive.

Would it be possible to adjust the code within these parameters? These limitations are the main issue when trying to create a solution.
