What are balanced trees and where are they used?

What are balanced trees and where are they used?

Balanced trees are data structures that maintain their height to ensure efficient operations. They're used in databases, memory management, and more.

Can you explain how they maintain balance?

They use rotations and specific algorithms to keep the tree balanced after insertions and deletions, ensuring optimal performance.

What are some common types of balanced trees?

Common types include AVL trees, Red-Black trees, and B-trees, each with unique balancing methods and use cases.

Why are balanced trees preferred over unbalanced trees?

Balanced trees provide better performance for search, insert, and delete operations, typically achieving O(log n) time complexity.

Can you give an example of a real-world application?

Sure! Balanced trees are often used in databases for indexing, allowing quick data retrieval and efficient storage.
