Evaluating Linked Lists

Types of Linked Lists

Singly Linked List

Structure: Each node has data and a pointer to the next node.
Operations:
1. Insertion: O(1) at head; O(n) at tail (unless a tail pointer exists).
2. Deletion: O(1) at head; O(n) elsewhere (need previous node).
3. Traversal: O(n), must visit each node in sequence.
4. Search: O(n), full traversal in worst case.

Doubly Linked List

Structure: Each node has data, previous pointer, and next pointer.
Operations:
1. Insertion/Deletion: O(1) at head or tail; O(1) in middle if node reference is known.
2. Traversal: O(n) forward or backward.

Nice try, unfortunately this paywall isn't as easy to bypass as you think. Want to help devleop the site?
