Array vs Linked List: Choosing the Right Data Structure

The main difference between an array and a linked list lies in how they store and access elements.

Arrays are a data structure that stores elements in contiguous memory locations, allowing for quick random access using indices. On the other hand, linked lists store elements as nodes with pointers to the next element, providing dynamic memory allocation and efficient insertions and deletions.

When deciding between an array and a linked list, consider the following scenarios:

• Array: Use arrays when you need fast access to elements by index, as arrays offer O(1) time complexity for random access. Arrays are also suitable for scenarios where the size of the data structure is known and fixed.
• Linked List: Opt for linked lists when you frequently need to insert or delete elements, as linked lists provide O(1) time complexity for these operations. Linked lists are ideal for scenarios where the size of the data structure may vary and dynamic memory allocation is preferred.

By understanding the strengths and weaknesses of arrays and linked lists, you can choose the right data structure for optimal performance based on the specific requirements of your application.
