Instructions

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

• In case of impossibilities, the function returns 0.

Expected function

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')
}
