Instructions

Complete the body of the function fibonacci.

 pub fn fibonacci(n: u32) -> u32 {
 }

This function receives a number n and returns the nth number in the fibonacci series.

The Fibonacci Series starts like this: 0, 1, 1, 2, 3, 5, 8, 13 etc...

Usag

Here is a possible test for your function:

use fibonacci2::fibonacci;

fn main() {
    println!("The element in the position {} in fibonacci series is {}",2, fibonacci(2));
    println!("The element in the position {} in fibonacci series is {}",4, fibonacci(4));
    println!("The element in the position {} in fibonacci series is {}",22, fibonacci(22));
    println!("The element in the position {} in fibonacci series is {}", 20, fibonacci(20));
}

And its output:

$ cargo run
The element in the position 2 in fibonacci series is 1
The element in the position 4 in fibonacci series is 3
The element in the position 22 in fibonacci series is 17711
The element in the position 20 in fibonacci series is 6765
