Please prepare a Progress Report for this two in a PDF file format. The content of the Progress Report should be: The logic ideas of all methods that you are required to implement with detailed steps and explanations. You must use java-like description or pseudo-code to present the logic idea of each method. It is even more illuminating to illustrate your logic ideas with examples of input list diagrams.

For example, Logic Idea for addFirst(Object item) method in the class, Step 1) Make a new node NN and store the Object item into the new node NN's data field. NN's prev gets this.head and NN's next gets this.head.next. Step 2) Assign NN to the prev reference in the node at head.next. Step 3) Then assign NN to the next reference in the dummy head node. Step 4) increase size of this list by one.
