Linked Lists: The Interviewer’s Favorite Puzzle
Linked lists are everywhere in coding interviews—and for good reason!
They’re perfect for testing how well you understand pointers and handle edge cases. Plus, they’re a great way to see if you can think step by step without getting lost in the links.
Whether it’s reversing a list, detecting cycles, or designing something like an LRU Cache, linked lists are a goldmine for interview questions.
If you’re struggling, check out this awesome resource that breaks down 90% of linked list problems into types: LeetCode Linked List Guide.
Examples:
- Reversing a list in-place
- Detecting cycles (Floyd’s Algorithm)
- Designing an LRU Cache
Pro Tip: If the problem involves "constant-time insertions/deletions" or "pointer manipulation", think linked lists!
Let’s Discuss:
- What’s your favorite linked list problem?
- Which interview question made you rethink pointers?
- Share a time when dummy nodes saved your code!
Quick question: Do you prefer drawing diagrams for linked lists or just keeping it all in your head? Let’s hear your approach! 👇
