Lec-55: Find Preorder, Postorder & Inorder of Binary Search Tree(BST) in Data Structure

👉Subscribe to our new channel:   / @varunainashots  

0:00 - Introduction
0:24 -Post order traversal
1:53 -Pre order
2:05 -In order
3:25 -Next element
6:14 -Post order

The major importance of tree traversal is that there are multiple ways of carrying out traversal operations unlike linear data structures like arrays, bitmaps, matrices where traversal is done in a linear order.

Each of these methods of traversing a tree have a particular order they follow:

For Inorder, you traverse from the left subtree to the root then to the right subtree.
For Preorder, you traverse from the root to the left subtree then to the right subtree.
For Post order, you traverse from the left subtree to the right subtree then to the root.

The idea of providing these questions is to evaluate GATE aspirants randomly from any topic of full Syllabus. Our aim is to give the you quality questions from full syllabus. Its just for your Practicing.
