Linked List Patterns
Learn the core linked list interview patterns including reversal, merge, fast-slow pointers, nth-from-end, k-group reversal, and random pointers
Why Linked Lists Matter
Linked list interviews are less about memorizing pointer tricks and more about staying disciplined with:
- pointer movement
- dummy nodes
- edge cases near the head
- splitting and reconnecting pieces safely
If arrays test indexing, linked lists test pointer reasoning.
