Instructions

Write a function ForEach that, for an int slice, applies a function on each elements of that slice.

Expected function

}

Usage

Here is a possible program to test your function :

package main

import "piscine"

func main() {
	a := []int{1, 2, 3, 4, 5, 6}
	piscine.ForEach(piscine.PrintNbr, a)
}

And its output :

$ go run .
123456
$
