In the context of binary trees, binary tree traversal is a key idea in data structures and algorithms. The left child and the right child are the two children of each node in a binary tree, which is a hierarchical data structure made up of nodes.
A binary tree traversal process entails going through and processing each node in a binary tree in a methodical sequence. Binary tree traversal can be divided into three categories:
1. Inorder Traversal: The nodes are visited in the following order in this traversal: left child, current node, then right child. It is advantageous for tasks like publishing the tree's elements in sorted order in the case of a binary search tree (BST) because the inorder traversal visits nodes in ascending order.
2. Preorder Traversal: In this case, you visit the nodes in this order: current node, left child, right child. Preorder traversal is frequently used to duplicate the tree or to conduct operations that require accessing the parent node before its descendants.
3.Post order Traversal:This traversal goes through the following nodes in the following order: left child, right child, current node. Postorder traversal is frequently used for activities like deleting nodes from a tree or evaluating expressions in a syntax tree.
