Binary Tree Explained: Introduction & Traversal (Preorder, Inorder, Postorder) | DSA for Beginners

Описание: Master the fundamentals of *Binary Trees* and their *Traversal* methods in this essential Data Structures and Algorithms (**DSA**) lecture!

A Binary Tree is a foundational concept in computer science. In this video, we clearly define a Binary Tree, show you how to identify valid structures, and, most importantly, break down the three core traversal techniques.

This is a must-watch for anyone preparing for technical interviews, coding contests, or learning data structures.

*Key Takeaways & Next Steps*

Binary Trees are a special type of tree where each node has at most two children.
The three main traversal types are Pre-order (PLR), Post-order (LRP), and In-order (LPR).
Watch our next video in the DSA series to see the implementation of these traversal algorithms!
