1) In this homework, you are supposed to modify the program you have written for the first homework. In the first homework, you are allowed to use only the basic array data structure. This time you have to use the List interface in Java Collections Framework. You should generate three separate versions of your program by using following three different implementations of the List interface;
a) Array List structure, ArrayList in Java Collections Framework,
b) Linked List structure, LinkedList in Java Collections Framework,
c) Your own Linked list structure named LDLinkedList. LDLinkedList should implement the List interface and extend the AbstractList in Java Collections Framework. You should use lazy deletion strategy in your Linked List implementation. In lazy deletion strategy, the nodes containing removed elements are moved to a separate Linked List for future use. When a new element is added, a node is obtained from this second list if one available. Of course, a new node should be created, otherwise.
You should analyze time complexity of four versions (including the one in the first homework). Analyze the theoretical running time. Measure experimental running time of your code for different size scenarios and compare it with the theoretical running time.
