Balanced Binary Tree Explained | Check Height Balanced Tree | DSA Trees | C++

In this video, we solve the classic DSA problem: Balanced Binary Tree.

A binary tree is height-balanced if the difference between the height of the left and right subtree of every node is at most 1.

We use a recursive approach to calculate the height of each subtree and check the balance condition efficiently.

Key Concepts Covered:
- Binary Tree basics
- Height of a tree
- Recursion in trees
- Optimized tree traversal

Approach:
- Use postorder traversal
- Return height if subtree is balanced
- Return -1 if subtree is unbalanced
- Final result depends on recursive checks

Time Complexity: O(n)
Space Complexity: O(h), where h is the height of the tree

This problem is very important for:
• DSA fundamentals
• Coding interviews
• Tree recursion practice
