What are some alternatives to using lists in C#?

In C#, you can consider using arrays, dictionaries, or collections like HashSet and Queue as alternatives to lists.

Can you explain when to use a dictionary instead of a list?

Sure! Use a dictionary when you need to store key-value pairs and require fast lookups by key, unlike lists which are indexed by position.

What about using arrays? Are they better than lists?

Arrays are fixed in size and can be more efficient in terms of memory and performance for large datasets, but they lack the flexibility of lists.

How does a HashSet differ from a list?

A HashSet stores unique elements and offers faster lookups, while a list allows duplicates and maintains the order of elements.

Can you give me an example of when to use a Queue?

A Queue is ideal for scenarios where you need to process items in a first-in, first-out (FIFO) manner, like task scheduling.
