What are the differences between binary search trees and other tree structures?

Binary search trees (BSTs) allow for efficient searching, insertion, and deletion. Unlike other trees, BSTs maintain a specific order where the left child is less than the parent and the right child is greater.

Can you explain the advantages of using a binary search tree?

Sure! BSTs provide average-case time complexities of O(log n) for search, insert, and delete operations, making them efficient for dynamic datasets.

What are some disadvantages of binary search trees?

One major disadvantage is that BSTs can become unbalanced, leading to O(n) time complexity for operations in the worst case. This can be mitigated with self-balancing trees like AVL or Red-Black trees.

How do binary search trees compare to hash tables?

While hash tables offer average O(1) time complexity for lookups, they do not maintain order. BSTs maintain sorted order but have O(log n) complexity for lookups.

Are there specific use cases where one is preferred over the other?

Yes, if you need ordered data and range queries, BSTs are preferred. For fast lookups without order, hash tables are better.
