Linked Lists

Module Contents

  1. Introduction to Linked Lists

Why Linked Lists exist. Deep dive into Hardware Reality: Stack vs Heap, Cache Locality, and the cost of pointer chasing.

  1. Singly Linked List

How to implement a Singly Linked List from scratch in Java and Go. Master insertions, deletions, and traversal.

  1. Doubly & Circular Lists

Upgrade your Linked Lists. Learn how Doubly Linked Lists enable bidirectional traversal and how Circular Lists create infinite loops.

  1. Operations (Reverse, Merge)

Master the most asked Linked List interview questions: Reversing a Linked List and Merging two sorted lists.

  1. Fast & Slow Pointers

Learn Floyd’s Cycle-Finding Algorithm. Understand how the Tortoise and Hare technique solves cycle detection in O(N) time and O(1) space.

  1. Skip Lists & Redis

Staff Level: Understand the probabilistic data structure behind Redis Sorted Sets. Achieve O(log N) search with Linked Lists.

  1. Module Review: Linked Lists

Review everything you learned about Linked Lists. Flashcards, Cheat Sheet, and Key Takeaways.

Linked Lists

[!NOTE] This module explores the core principles of Linked Lists, deriving solutions from first principles and hardware constraints to build world-class, production-ready expertise.

1. Practice

[!NOTE] Looking for hands-on algorithmic exercises? We have migrated all coding challenges for this module into the Problem Vault to give you a centralized, focused practice environment.
