fibonacci

Instructions

Write an recursive function that returns the value of fibonacci sequence matching the index passed as parameter.

The first value is at index 0.

The sequence starts this way: 0, 1, 1, 2, 3 etc...

A negative index will return -1.

for is forbidden for this exercise.

Expected function

package main

func Fibonacci(index int) int {

}

Usage

Here is a possible program to test your function :

package main

import (
        "fmt"
        piscine ".."
)

func main() {
	arg1 := 4
	fmt.Println(piscine.Fibonacci(arg1))
}

And its output :
