Tree Data Structure Explained: Nodes, Hierarchy & Real-World Uses | DSA Full Course

Описание: What is a Tree Data Structure and why is it essential for non-linear data organization? In this lecture, we explore the hierarchical world of trees, from the root node to the furthest leaf.

In this video, you will discover:
1. The Concept: Why trees are "non-linear" and how they differ from arrays or lists.
2. Anatomy of a Tree: A detailed breakdown of nodes, edges, roots, and leaves.
3. Hierarchy: Understanding parent, child, and sibling relationships.
4. Tree Metrics: How to calculate the size, depth, and height of your data structure.
5. Practical Applications: See how trees power your computer's file system, databases, and even HTML.

Whether you're preparing for technical interviews or learning Data Structures and Algorithms (DSA), this lecture covers the foundational logic you need.
