Instructions

Write a function that returns true if the string passed as the parameter only contains alphanumerical characters or is empty, otherwise, and returns false.

Expected function

func IsAlpha(s string) bool {

}

Usage

Here is a possible program to test your function :

package main

import (
	"fmt"
	"piscine"
)

func main() {
	fmt.Println(piscine.IsAlpha("Hello! How are you?"))
	fmt.Println(piscine.IsAlpha("HelloHowareyou"))
	fmt.Println(piscine.IsAlpha("What's this 4?"))
	fmt.Println(piscine.IsAlpha("Whatsthis4"))

}

And its output :

$ go run .
false
true
false
true
$
