Instructions
Write a function that returns the nth rune of a string.

func NRune(s string, n int) rune {
}
Usage
Here is a possible program to test your function :
package main
import (
"github.com/01-edu/z01"
"piscine"
)
func main() {
z01.PrintRune(piscine.NRune("Hello!", 3))
z01.PrintRune(piscine.NRune("Salut!", 2))
z01.PrintRune(piscine.NRune("Bye!", -1))
z01.PrintRune(piscine.NRune("Bye!", 5))
z01.PrintRune(piscine.NRune("Ola!", 4))
z01.PrintRune('\n')
}
And its output :
$ go run .
la!
$
