Instructions

• Write a function that counts the runes of a string and that returns that count.

Expected function

func StrLen(str string) int {

}

Usage

Here is a possible program to test your function :

package main

import (
	"fmt"
	piscine ".."
)

func main() {
	str := "Hello World!"
	nb := piscine.StrLen(str)
	fmt.Println(nb)
}

And its output :
