What are some examples of mutable collections in programming?

Mutable collections are data structures that can be changed after their creation. Examples include lists, sets, and dictionaries.

Can you explain how a list is mutable?

Sure! A list can have items added, removed, or changed. For instance, in Python, you can use methods like append() or remove() to modify a list.

What about sets? How are they mutable?

Sets are also mutable. You can add or remove elements using methods like add() and discard(). However, sets do not allow duplicate values.

Are dictionaries mutable too?

Yes, dictionaries are mutable. You can change the value associated with a key, add new key-value pairs, or remove existing ones.
