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!

## What does "Removing Adjacent Duplicates from a String" Mean?
This means that we will remove all extra instances of a character when multiple instances are found together. In other words, only one instance should remain after this process. 

> Lower and upper case letters are considered different characters. Example: string `Hhelo` does not contain any duplicates.
