WebJan 26, 2024 · Next, we'll look at some techniques used in traversing a binary tree. What is Tree Traversal? Traversing a tree means visiting and outputting the value of each node in a particular order. In this tutorial, we will use the Inorder, Preorder, and Post order tree traversal methods. WebDetailed Explanation : 1. First, we define the Dictionary class with a private instance variable root, which is a reference to the root node of the Binary Search Tree. public class Dictionary { private Node root; 2. Next, we define the constructor for the Dictionary class, which simply initializes the root variable to null.

WebMay 23, 2024 · The idea behind the BFS algorithm for trees is to maintain a queue of nodes that will ensure the order of traversal. At the beginning of the algorithm, the queue contains only the root node. We'll repeat these steps as long as the queue still contains one or more nodes: Pop the first node from the queue WebSteps for PreOrder traversal are: Visit the node.
