What are the performance implications of using dynamic arrays?

Dynamic arrays offer flexibility in size but can incur performance costs during resizing operations.

Can you explain how resizing affects performance?

When a dynamic array resizes, it typically involves allocating a new array and copying elements, which is O(n) time complexity.

Are there scenarios where dynamic arrays are preferred despite the performance costs?

Yes, dynamic arrays are preferred when frequent size changes are expected, as they provide easier management compared to static arrays.

What alternatives exist to dynamic arrays?

Alternatives include linked lists, static arrays, and other data structures like vectors in C++ or ArrayLists in Java.
