What are the main differences between an array and a linked list in data structures?

Answer 1

Arrays and linked lists are both linear data structures, but they have key differences. Arrays store elements in contiguous memory locations, making access fast (O(1)) but resizing and insertion/removal expensive (O(n)). Linked lists, on the other hand, store elements in nodes connected by pointers, allowing efficient insertions and deletions (O(1)) but slower access times (O(n)) due to the need to traverse nodes.
