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

# A Final Note
In this course, we learned how to convert iterative code to recursive code, and we reviewed many different problems using recursion.

Both recursive and iterative approaches can be used to solve a problem. 

> Recursive programs can be written iteratively and iterative programs can be written recursively. 

However, the key difference is to choose the right approach in interviews unless stated otherwise. Recursive programs have greater **space** complexity than iterative programs since all functions will remain in the **memory stack** until the **base case** is satisfied. 
However, recursion provides a clean and simple way to write code. It is easier to solve many problems recursively, including graph traversals, Pascal's Triangle, etc.

We have reached the end of this course. We have covered all the concepts to help you get started with performing recursion using Python.
