The ultimate recursion guide! Master basics, solve real-world problems, and get interview-ready in hours with FAANG engineers’ proven strategies.

If you’ve ever struggled with solving coding problems using recursion, or if you need to brush up your recursion skills for an interview, this course is for you! We will start with the basics of recursion before we practice solving actual coding problems. You’ll have access to detailed explanations and visualizations for each problem to help you along the way.

By the time you have completed this course, you’ll be able to use all the concepts of recursion to solve complex, real-world problems. We hope that this course will help you ace all the recursion related questions during interviews at top tech companies!

Recursion for Coding Interviews in Python

# What is a Linked List?
A linked list is a data structure that stores data in the form of a sequence of nodes. Each Node holds **data** along with a **forward pointer** to the next Node in the list. 
 

As depicted in the illustration below, a linked list is formed by Nodes that are connected like a chain.

# What does "Reversing a Linked List" Mean?

A linked list contains a sequence of data. Our task is to reverse that sequence:




In this lesson, we will learn how to reverse a linked list using recursion.
