What are the different types of collections in programming?

In programming, collections are data structures that hold multiple values. Common types include arrays, lists, sets, and maps.

Can you explain the difference between a list and a set?

Sure! A list is an ordered collection that allows duplicate elements, while a set is an unordered collection that does not allow duplicates.

When would I use a map instead of a list?

You would use a map when you need to associate keys with values, allowing for fast lookups based on the key.

Are there any performance differences between these collection types?

Yes, performance can vary. For example, accessing an element in a list is O(1), while searching in a set is typically O(1) as well, but insertion and deletion can differ.
