Data Structures and Algorithms The Complete Masterclass - Implementing Depth-first Search - Algorithm: Tree Traversals

The video tutorial explains the implementation of Depth First Search (DFS) methods in binary trees, focusing on preorder, inorder, and postorder traversals. It provides a detailed walkthrough of the preorder traversal, including the use of recursion and call stacks. The tutorial also briefly introduces inorder and postorder traversals, highlighting the differences in their sequences. The video concludes with a preview of the next lecture on Breadth First Search (BFS) and its relevance to understanding queues.

How can the results of the traversals be visualized step by step?

What are the differences between preorder, inorder, and postorder traversals?

What is the order of operations in the inorder traversal method?

Describe the steps involved in the postorder traversal method.
