## About the Complete Guide to Recursion and Backtracking

Welcome to the Complete Guide to Recursion and Backtracking! The purpose of this guide is to provide an introduction to two fundamental concepts in computer science: Recursion and Backtracking. We'll explore what they are, how they work, and why they are crucial tools in problem-solving and algorithm development. Whether you are a beginner or an experienced programmer, this guide will assist you in grasping knowledge about recursion and backtracking effectively.

### Basic terminologies of Recursion and Backtracking

While learning about Recursion and Backtracking in this Complete Guide, you will come across some common terms that will be used multiple times. Some of these terms are:

1. Recursion: A function calling itself, often used to solve problems by breaking them into smaller, similar subproblems.
2. Base Case: A stopping condition that prevents infinite recursion.
3. Recursive Call: when a function invokes itself as part of its execution
4. Recursive Stack: A data structure that keeps track of function calls in a recursive process, allowing for returning to previous function calls when necessary.
5. Decision Space: The set of all possible choices or decisions that can be made during a backtracking algorithm
6. State Space: A representation of all possible states of a problem. Backtracking explores this space to find solutions.

## Why Recursion and Backtracking is needed?

We use recursion and backtracking to break down complex problems into smaller, manageable parts, which results in elegant and concise code while handling recursive data structures efficiently and exploring systematically for solutions.

## Reviews

I think GFG's study plan is very well-organized. The way they arrange the study materials is great, and it has really helped me a lot.

The roadmap explains everything clearly and comes with useful practice questions to help understand the topics better. Great job, GeeksforGeeks!

Asha Bisht

Certainly, GeeksforGeeks has really helped me understand important topics really well, and because of that, I got a great job.

Aryan Singh

This guide is a great way to learn the basics of data structures and algorithms. I'm really happy with it.
