In this tutorial, I will teach Pre-order traversal in Binary Tree.
In computer science, tree traversal is a form of graph traversal and refers to the process of visiting each node in a tree data structure.
In PreOrder traversal, the root is visited first, followed by the left subtree and the right subtree, hence it is also known as NLR (nod-left-right) algorithm as well.
It's a process to visit all nodes of a binary tree. It is also used to search a node in the binary tree.
