Part 1: Complete the implementation of the removeFirst() method for DoubleLinkedList

drawing portion only needed

A.) The removeFirst() method is not implemented. You need to implement it. Notice that removeFirst() returns the element being removed. To start, use a sketchbook or a drawing program to illustrate a doubly-linked list with at least three nodes. (For your convenience, a draw.io template of a double-linked list node is provided in Canvas.) Think through what should happen when you remove the first node in a list with multiple nodes. Perhaps number the operations. Remember to keep track of pointers.

Part 2: Complete the implementation of the removeLast() method for DoubleLinkedList

B.)The removeLast() method has not been implemented. Notice that removeLast() returns the element being removed. As before, use a sketchbook or a drawing program to illustrate a doubly-linked list with at least three nodes. Think through what should happen when you remove the last node in a list with multiple nodes.
