Linked Lists vs Arrays: Which is Better?

What are the main differences between linked lists and arrays?

Linked lists are dynamic and can grow or shrink in size, while arrays have a fixed size. Arrays allow for faster access to elements, but linked lists are better for insertions and deletions.

When should I use a linked list instead of an array?

Use a linked list when you need frequent insertions and deletions, or when the size of the data structure is unknown at compile time.

Are there any performance trade-offs I should be aware of?

Yes, arrays provide O(1) time complexity for access, while linked lists provide O(n) for access. However, linked lists have O(1) for insertions and deletions.

Can you give me an example of when to use each?

Use arrays for static data like a list of days in a week, and linked lists for dynamic data like a playlist where songs can be added or removed frequently.
