The ultimate guide to recursion interviews with strategies developed by FAANG engineers. Practice with real-world interview questions, detailed explanations, and visualizations to prep faster.

If you’ve got an interview coming up and want to brush up on your knowledge, or if you’ve ever struggled with solving coding problems using recursion, you'll find this course helpful.
 
You’ll start with the basics of what recursion is and why it’s important before diving into what it looks like in practice. You’ll see how recursion can help you solve a variety of different math, string, and data structure problems by using interactive code playgrounds that you can execute directly in your browser. You’ll have access to detailed explanations and visualizations for each problem to help you along the way.  
 
By the time you’re done, you’ll be able to use what you’ve learned to solve complex real-world problems and even advance more easily through your interviews at top tech companies.

Recursion for Coding Interviews in Java

Ever wonder why programming languages such as *Haskell*, *Scala*, *JavaScript*, etc are so in demand nowadays? This is because these languages are based on **Functional Programming**, meaning the system is built around the concept of recursion. Entire languages are now being based on recursion. Interesting, right? 

In general, almost any problem that can be solved with a non-recursive code can also be solved by recursion. In fact, most problems that can't be solved by a non-recursive code can even be solved by recursion. This doesn't mean, however, that you should always use recursion to solve the problem. This is exactly what we will be discussing in this lesson. 

This lesson covers all the factors of when you should use Recursion.
