Arrays Linked Lists Questions
The main difference between an array and a linked list is the way they store and access data.
- Array: An array is a fixed-size data structure that stores elements of the same type in contiguous memory locations. It allows direct access to elements using their index, which makes accessing elements faster. However, the size of an array is fixed and cannot be easily changed, requiring the creation of a new array with a different size if needed.
- Linked List: A linked list is a dynamic data structure that consists of nodes, where each node contains a value and a reference (or link) to the next node in the list. Unlike an array, a linked list does not require contiguous memory allocation, allowing for efficient insertion and deletion of elements. However, accessing elements in a linked list requires traversing the list from the beginning, which can be slower compared to direct access in an array. Additionally, linked lists can be easily resized by adding or removing nodes.
