# Top 6 Online Courses to Learn Recursion for Beginners in 2022 - Best of Lot

Hello guys,  if you want to learn and Master Recursion and looking for the best resources like books, online courses, and tutorials then you have come to the right place. Earlier, I have shared the best dynamic programming courses, and 15 Recursion exercises for beginners, and today, I am going to share the best courses to learn Recursion for beginners. Recursion is the process by which a function calls itself again and again directly or indirectly. These types of functions are called recursive functions. All successful software programmers need to have an understanding of how recursive functions work as well as how to build recursive functions.

If you are a programmer then Recursion is your friend. Recursion helps you to break down big and complex programs into smaller parts. A function that calls itself directly or indirectly is called a recursive function.

Recursive algorithms can be used to solve complex problems particularly involving recursive data structures like linked lists, binary trees, strings, numbers, and graphs.

In recursive functions, there is a base condition that needs to be provided and then the solutions of bigger problems are expressed using smaller problems. This base condition will stop the recursive function from executing endlessly and going on an infinite loop. Once the base condition is met, the recursive function will stop and exit.

The basic idea behind recursion is to break down bigger, complex programs into smaller, manageable parts. And then, you can add one or more base conditions that will stop the function from looping endlessly.

Recursive functions are used in C++, Java, Python, and other programming languages. They also play a big role in solving dynamic programming-based coding problems which can be really challenging during a coding interview.

## 5 Best Recursion Online Courses and Tutorials for Beginners to Learn in 2022

There is no doubt that Recursion is a difficult concept to master. While it's easy to say that you just need to find the base case and it's nothing but function calling itself. Understanding and applying Recursion on real-world problems like reversing a linked list or binary tree requires practice and that's where you need resources.

We have compiled a list of the best courses that will help you master recursive functions and make you a more expert programmer. These are the best online courses to learn Recursion from popular online learning websites like Udemy, Coursera, Educative, and edX.  You can join any of these courses or a couple of them to learn and master Recursion in 2022.

Keep reading to check out the list.

Here is a list of common questions programmers ask about Recursion, particularly beginners who have just started with recursion or want to learn Recursion concepts.

1. What is Recursion?

It is defined as the process by which a function calls itself again and again directly or indirectly.

2. What is Recursion used for?

Recursion is mainly used to solve complex problems breaking them down into smaller problems. This is done with the help of recursive functions.

3. Who invented Recursion?

The theory behind recursion was first invented in the 20th century by Thoralf Albert Skolem.

4. What are recursive data structures?

Tree, Graph, and Linked list are recursive data structure because if you take out one element the remaining are still a tree, graph or linked list data structure and you can process them like original tree, graph, or linked list.

5. What is base case on recursion?

The last case after which recursion rolls or finishes are known as base case. For example factorial(0)= 1 is the base case for calculating factorial and reaching at the end of linked list or binary tree is base case.

I never understood recursion properly and always struggle to come up with recursive solution, can't even reverse a linked list using recursion after 15 years of experience, can you suggest a course for this.
