foreach

Instructions

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

Expected function

func ForEach(f func(int), a []int) {

}

Usage

Here is a possible program to test your function :

package main

import "fmt"

func PrintNbr(n int) {
	fmt.Print(n)
}

func main() {

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

And its output :

$ go run .
123456
$
