What is the time complexity of arrays compared to linked lists?

What is the time complexity of arrays compared to linked lists?

Arrays have O(1) time complexity for access, while linked lists have O(n). However, linked lists excel in insertions.

Why are insertions faster in linked lists?

Insertions in linked lists are faster because they only require changing pointers, while arrays may need shifting elements.

What about space complexity?

Arrays have a fixed size, leading to O(n) space complexity, while linked lists use O(n) as well but can grow dynamically.

When should I use one over the other?

Use arrays for fast access and when size is known. Use linked lists for frequent insertions/deletions.
