Tree Traversal: Tree traversal is a method of visit all the nodes of the tree and also displays their data. All the nodes are connecting via link which means edge. So the edge is used to visit all the nodes in the tree. Tree traversal is classified into three orders. They are: Inorder traversal Preorder traversal Postorder traversal Inorder traversal - In this method, the left subtree is visited first after that the root node and finally right subtree. In tree traversal every node may represent a subtree itself. Preorder traversal - In this method, the root is visited first after that the left subtree node and finally right subtree node. Postorder traversal - In this method, the left subtree node is visited first after that the right subtree node and finally root node is visited.

Program Plan Intro

Tree Traversal:

Tree traversal is a method of visit all the nodes of the tree and also displays their data. All the nodes are connecting via link which means edge. So the edge is used to visit all the nodes in the tree. Tree traversal is classified into three orders. They are:

Inorder traversal

Preorder traversal

Postorder traversal

Inorder traversal - In this method, the left subtree is visited first after that the root node and finally right subtree. In tree traversal every node may represent a subtree itself.

Preorder traversal - In this method, the root is visited first after that the left subtree node and finally right subtree node.

Postorder traversal - In this method, the left subtree node is visited first after that the right subtree node and finally root node is visited.

Is it possible to implement a sorted linked list using a DLL? What is the advantage of using a DLL versus a single linked list? Back up your point with a real example or application.

For this assignment, you need to implement link-based List and derivative ADTs in Java. To complete this, you will need the following: A LinkNode structure or class which will have two attributes - a data attribute and a pointer attribute to the next node. The data attribute of the LinkNode should be the Money class of Lab 1. A Singly Linked List class which will be composed of three attributes - a count attribute, a LinkedNode pointer/reference attribute pointing to the start of the list and a LinkedNode pointer/reference attribute pointing to the end of the list. Since this is a class, make sure all these attributes are private. The attribute names for the Node and Linked List are the words in bold in #1 and #2. For the Linked List, implement the most common linked-list behaviors as explained in class - getters/setters/constructors/destructors for the attributes of the class, (a) create new list, (b) add data, (c) delete data, (d) find data, (e) count of data items in the…
