How do lists and iterators compare in terms of performance?

Lists are generally faster for indexing and accessing elements, while iterators are more memory efficient for large datasets.

Can you explain why iterators are more memory efficient?

Iterators don't store all elements in memory at once; they generate items on-the-fly, which saves memory.

Are there specific scenarios where one is better than the other?

Yes, use lists when you need fast access and iterators for large datasets or when you want to process items one at a time.

What about performance in terms of speed?

Lists are faster for random access, but iterators can be faster for sequential access, especially in large collections.
