What are the performance differences between lists and arrays in programming?

Lists and arrays differ in performance mainly in terms of memory allocation and access speed. Arrays have a fixed size and allow faster access due to contiguous memory allocation, while lists are dynamic and can grow or shrink, but may have slower access times.

Can you explain why arrays are faster than lists?

Arrays are faster because they store elements in contiguous memory locations, allowing for quicker access via indexing. Lists, on the other hand, may involve additional overhead for managing pointers and dynamic memory.

Are there any scenarios where lists are better than arrays?

Yes, lists are better when you need dynamic resizing or frequent insertions and deletions, as they can easily adjust their size without reallocating memory.

What about the memory usage of lists compared to arrays?

Arrays typically use less memory since they allocate a fixed size, while lists may use more due to overhead for pointers and dynamic memory management.
