In this tutorial, I will teach In-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-order Traversal :
In this traversal method, the left subtree is visited first, then the root and later the right sub-tree. We should always remember that every node may represent a subtree itself.

If a binary tree is traversed in-order, the output will produce sorted key values in ascending order.

Traversal is a process to visit all the nodes of a tree and may print their values too. Because all nodes are connected via edges (links) we always start from the root (head) node. That is, we cannot randomly access a node in a tree. There are three ways which we use to traverse a tree −

In-order Traversal
Pre-order Traversal
Post-order Traversal
Generally, we traverse a tree to search or locate a given item or key in the tree or to print all the values it contains.
