Binary Tree Traversal Techniques - DFS vs BFS - DFS Preorder vs Inorder vs Postorder

Explore different binary tree traversal techniques in this comprehensive tutorial. Learn about Depth First Search (DFS) and Breadth First Search (BFS) approaches, with a focus on DFS methods including pre-order, in-order, and post-order traversals. Understand the process of visiting each node in a tree data structure exactly once, and how these techniques are classified based on the order of node visitation. Dive into detailed explanations of each traversal method, complete with diagrams and examples to illustrate the concepts. Gain insights into when to use each traversal technique and their applications in various scenarios, such as topological sorting and retrieving keys in ascending order in Binary Search Trees.
