Segment Tree Construction Explained | Range Sum Query | Data Structures

Learn how to build a Segment Tree from scratch to solve the Range Sum Query problem efficiently! 🌳

In this video, we break down the construction of a Segment Tree, a powerful data structure used frequently in competitive programming and algorithm interviews. We move from the naive O(N) approach to the efficient tree-based structure.

Key Topics Covered:
🔹 Why use Segment Trees?
🔹 Visualizing the Binary Tree structure
🔹 Step-by-step construction logic
🔹 C++ Implementation code walkthrough
🔹 Time and Space Complexity Analysis

Perfect for beginners in Data Structures and Algorithms! 🚀
