What are the best data structures for performance in programming?

The best data structures for performance often depend on the specific use case, but generally, arrays, hash tables, and trees are top choices.

Can you explain why hash tables are so efficient?

Hash tables offer average-case constant time complexity for lookups, insertions, and deletions, making them very efficient for many applications.

What about trees? When should I use them?

Trees, especially binary search trees, are great for maintaining sorted data and allow for efficient range queries and ordered traversals.

Are there any scenarios where linked lists are preferred?

Yes, linked lists are preferred when you need frequent insertions and deletions, as they can be done in constant time without reallocating memory.
