What are the performance benefits of using sets in programming?

Using sets can significantly improve performance for operations like membership tests, as they offer average O(1) time complexity.

Can you explain how sets differ from lists in terms of performance?

Certainly! Sets are optimized for fast membership checks, while lists require O(n) time for the same operation.

Are there any specific scenarios where using a set is more advantageous?

Yes, sets are particularly useful when you need to ensure uniqueness or perform operations like unions and intersections efficiently.

What about memory usage? Do sets consume more memory than lists?

Sets may use more memory than lists due to their underlying hash table structure, but the trade-off is often worth it for performance.

Can you give an example of when to use a set over a list?

Sure! If you're tracking unique user IDs in a system, using a set would be ideal to avoid duplicates and allow for quick lookups.
