What are the differences between collection types in programming?

In programming, collection types refer to data structures that store multiple values. Common types include arrays, lists, sets, and dictionaries. Each has unique characteristics and use cases.

Can you explain how arrays and lists differ?

Sure! Arrays have a fixed size and store elements of the same type, while lists are dynamic and can hold elements of different types.

What about sets? How are they different from lists?

Sets are unordered collections of unique elements, meaning they do not allow duplicates, whereas lists can contain duplicate values and maintain the order of elements.

When should I use a dictionary instead of a list?

Use a dictionary when you need to associate keys with values for quick lookups. Lists are better for ordered collections of items.
