The digital world we live in has given companies and people access to staggering amounts of data, and anyone that can make use of that to drive valuable insights stands to benefit. The ability to work with large amounts of data is becoming a standard requirement for countless jobs across multiple industries.

Enter R, probably the most well-known language for data analysis. It's been used for years due to its robust statistical functionality, outstanding graphing ability, and extensibility through packages.

This interactive course will get you up to speed and assumes no prior knowledge of R. You'll start with the very basics and work your way up to advanced concepts like exception handling. By the time you're done, you'll be able to write detailed, useful code in R yourself.

# Problem Statement
Implement a **recursive function** that takes a number $n$ as input, and output the $nth$ term of the Fibonacci series.

The Fibonacci sequence is $0, 1, 1, 2, 3, 5, 8, 13, 21$ where the nth term is the sum of $(n-1)th$ and $(n-2)th$ term.

> The $0th$ term is $0$ and the $1st$ term is $1$. Therefore, the $2nd$ term is $0 + 1 = 1$.


## Input
A `testVariable` that contains the $nth$ term

## Output
The $nth$ term in the Fibonacci series, i.e., the element in the Fibonacci series at index `testVariable`

## Sample Input
```
6
```
## Sample Output
```
8
```
