Instructions

Write a function that returns true if the string passed in parameter only contains numerical characters, and that returns false otherwise.

Expected function

func IsNumeric(s string) bool {

}

Usage

Here is a possible program to test your function :

package main

import (
	"fmt"
	"piscine"
)

func main() {
	fmt.Println(piscine.IsNumeric("010203"))
	fmt.Println(piscine.IsNumeric("01,02,03"))
}

And its output :

$ go run .
true
false
$
