Gain insights into fundamental and advanced C# programming concepts. Learn about conditional statements, loops, methods, arrays, classes, inheritance, interfaces, and delegates through practical challenges.

This course introduces you to fundamental programming concepts in C#, one of the most popular languages in the world. The highly interactive course begins with a simple Hello world program and proceeds on to cover common concepts such as conditional statements, loop statements, and methods in C#. It also reflects upon the idea of arrays as well as the power they give to the programmer to write better code. Finally, it dives deeper in order to teach about advanced concepts such as classes, inheritance, interfaces, and delegates in C# through interactive challenges and exercises.

C# for Programmers: A Practical Guide

## Problem Statement

[Previously](https://www.educative.io/courses/c-sharp-for-programmers-a-practical-guide/exercise-2-fibonacci-sequence-upto-n-number-of-terms/draft) you wrote the code for generating *Fibonacci* series. In this exercise, you have to implement *Fibonacci series* again but using **Recursion** instead.

You're given the *method* `fibonacci` that takes integer `n` that tells the *range* up to which you want to calculate the series. 

Now implement this logic using *recursion*.
