What are the different types of collections in data structures?

In data structures, collections can be categorized into several types, including arrays, lists, sets, and maps. Each type has its own characteristics and use cases.

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 should I use a map instead of a list?

You should use a map when you need to associate keys with values for quick lookups, whereas a list is better for ordered collections of items.

What are some real-world applications of these collection types?

Real-world applications include using lists for managing tasks, sets for unique items like user IDs, and maps for storing user profiles with unique usernames.
