Balanced vs. Unbalanced Trees
Explore the differences between balanced and unbalanced trees and understand how tree height impacts the efficiency of operations like searching, inserting, and deleting. Learn why maintaining balance is crucial in binary search trees and discover self-balancing trees such as AVL and red-black trees that ensure consistent performance.

The shape of a tree has a major effect on how efficiently it performs operations. A balanced tree keeps its branches at roughly similar heights, while an unbalanced tree grows much deeper on one side than the other.
When a tree stays balanced, it remains relatively short, which means you can reach nodes in fewer steps. When it becomes unbalanced, it gets taller, and operations may take much longer.
