As binary trees are the most important class of m-ary trees and have a wide range of applications, our focus here is on binary tree traversals. There are three elegant recursively defined methods for traversing

Let’s see how to implement these binary tree traversals in Java and what is the algorithm for these binary tree traversals. 2.1. Inorder Binary Tree Traversal In the in-order binary tree traversal, we visit the left sub tree than current node and finally the right sub tree. Here is the...
A binary tree is a tree data structure in which each node has at most two children, referred to as the left child and the right child. The topmost node in the tree is called the root. Nodes with no children are known as leaves. Binary trees can be of different types, such as ...
There are three depth-first traversal sequences for a binary tree, preorder, inorder, and postorder traversal sequences. My literature survey indicates the most references present the depth-first traversals algorithms as recursive ones. Some literatures have introduced the non-recursive algorithms only...

Because of the inherent recursive structure of trees (each node has smaller left and right subtrees), tree traversals are often implemented using recursive algorithms. Let's explore the common traversal methods. In-order traversal In an in-order traversal, we visit nodes in the following order...
Recall from Part 1 that an array is stored linearly in memory, requires explicit resizing when the array's capacity is reached, and suffers from linear searching time.In this third installment of the article series, we will examine a new data structure, the binary tree. As we'll see, ...

Depth First Search (DFS)is when the traversal moves down the tree all the way to the leaf nodes, exploring the tree branch by branch in a downwards direction. There are three different types of DFS traversals: These three Depth First Search traversals are described in detail on the next pag...
