Binary Tree Traversal

Binary Tree Traversal

A binary tree is a hierarchical data structure where each node has at most two child nodes: a left child and a right child. Traversal involves systematically visiting each node in the tree, ensuring that every node is accessed exactly once. This process is very important for various operations like printing the tree’s contents, searching for specific elements, and evaluating expressions represented by the tree....

Types of Binary Tree Traversal

Pre-order Traversal In-order Traversal Post-order Traversal Level-order Traversal...

1. In-Order Traversal

In in-order traversal, the left child is visited first, followed by the node itself, and then the right child. This can be visualized as Left – Root – Right....

2. Pre-Order Traversal

In pre-order traversal, the node is visited first, followed by its left child and then its right child. This can be visualized as Root – Left – Right....

3. Post-Order Traversal

In post-order traversal, the left child is visited first, then the right child, and finally the node itself. This can be visualized as Left – Right – Root....

4. Level-Order Traversal

In level-order traversal, the nodes are visited level by level, starting from the root node and then moving to the next level. This can be visualized as Level 1 – Level 2 – Level 3 – …....
