What are the performance differences between lists and arrays?

Lists and arrays differ in performance mainly due to their underlying structures. Arrays have fixed sizes and allow for faster access times, while lists are dynamic and can grow or shrink, which may introduce overhead.

Can you explain why arrays are faster for certain operations?

Arrays provide faster access because they store elements in contiguous memory locations, allowing for quick index-based access. This is not always the case with lists, which may require traversing nodes.

What about memory usage? How do they compare?

Arrays typically use less memory than lists because they have a fixed size and don't require additional memory for pointers or references, which lists do.

Are there specific scenarios where I should prefer one over the other?

Yes, if you need fast access and know the size of your data in advance, use arrays. If you need flexibility in size and frequent insertions or deletions, lists are better.
