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 ...
First of all, we need to learn two structures: (1) Binary Tree (2) Deque abinary treeis atree data structurein which each node has at most twochildren, which are referred to as theleft childand theright child. adouble-ended queue(abbreviated todequeis anabstract data typethat generalizes...

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...
Binary Tree Traversals A traversal is an algorithm for visiting some or all of the nodes of a binary tree one and only one time in some defined order. L---moving left, V---visiting the node, R---moving right , the possible combination of traversal: LVR LRV VLR VRL RVL RLV...
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...

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 a nonempty binary tree, which are as follows: • In a preorder traversal, the...
