What are some practical use cases for tree sets in programming?

Tree sets are useful for maintaining a sorted collection of unique elements. They can be used in scenarios like implementing a priority queue, managing a leaderboard, or storing a collection of unique items that need to be retrieved in sorted order.

Can you explain how a tree set differs from a hash set?

Certainly! A tree set maintains elements in a sorted order and allows for range queries, while a hash set does not maintain any order and offers faster average time complexity for add, remove, and contains operations.

What are the performance implications of using a tree set?

Tree sets have a time complexity of O(log n) for basic operations like add, remove, and contains due to their underlying balanced tree structure. This is generally slower than hash sets, which have O(1) average time complexity.

In what scenarios would you prefer a tree set over a hash set?

You would prefer a tree set when you need sorted data, require range queries, or need to maintain a unique collection of items in a specific order.
