C++: Hash Table vs Binary Tree

What are the main differences between hash tables and binary trees in C++?

Hash tables provide fast access using keys, while binary trees maintain sorted data and allow for ordered traversal.

When should I use a hash table instead of a binary tree?

Use a hash table for quick lookups and insertions, especially when order isn't important. Use a binary tree for sorted data.

Can you give me an example of when a binary tree is more beneficial?

Sure! A binary tree is beneficial for applications like priority queues or when you need to perform range queries.

What are the time complexities for operations in both data structures?

Hash tables have average O(1) for lookups, while binary trees have O(log n) for balanced trees and O(n) for unbalanced ones.
