Can you explain the differences between arrays and linked lists?

Can you explain the differences between arrays and linked lists?

Sure! Arrays are fixed-size data structures that store elements in contiguous memory locations, while linked lists consist of nodes that are connected via pointers, allowing for dynamic size.

What are the advantages of using linked lists over arrays?

Linked lists allow for efficient insertions and deletions since you don't need to shift elements like in arrays. They also can grow and shrink in size dynamically.

Are there any disadvantages to using linked lists?

Yes, linked lists have a higher memory overhead due to storing pointers, and accessing elements can be slower since you can't directly index them like in arrays.

In what scenarios would you prefer to use an array?

Arrays are preferable when you need fast access to elements via indexing, and when the size of the data set is known and fixed.
