Cover of the exclusive book: Linked List Problems

Did you know that the algorithms dealing with L1, L2 and L3 cache in your computer rely on Linked List?

The calculations for Rocket and Satellite launches in NASA use Linked Lists to store numbers and perform critical calculations.

These are just 2 instances of Linked List. It is one of the most used Data Structures and you should definitely master it before you jump into the real world.

About The Book

This book “Linked List Problems: For Interviews and Competitive Programming” is a deep dive into Linked List Data Structure, core techniques and Practice problems on Linked List. On completing this book, you will have these core skills:

  • Strong hold on Linked List (Research Level)
  • Easily solve any Linked List problem in Coding Interview and Competitive Programming Contests
  • Design Custom Data Structures for real-life applications

This book is divided into 4 sections:

  • Fundamentals of Linked List: This section builds your fundamentals. We explain how to implement Linked List using Industry standard, core operations along with Time and Space Complexity Analysis. This burst several misconceptions and assumptions a programmer makes about Linked List.

  • Types of Linked Lists: This section builds you hold on twisting Linked List as per your requirements to solve a problem.

  • Core Linked List Techniques: This is the most important section which presents you all the tools and techniques you need to conquer Linked Lists.

  • Practice Problems on Linked List: Practice is a key to success for Coding Interviews, Competitive Programming and Efficient Problem Solving. Practice one problem everyday by implementing the solution on your own.
