map

Instructions

Write a function Map that, for an int array, applies a function of this type func(int) bool on each elements of that array and returns an array of all the return values.

Expected function

func Map(f func(int) bool, arr []int) []bool {

}

Usage

Here is a possible program to test your function :

package main

import (
	"fmt"
	piscine ".."
)

func main() {
	arr := []int{1, 2, 3, 4, 5, 6}
	result := piscine.Map(piscine.IsPrime, arr)
	fmt.Println(result)
}

And its output :

student@ubuntu:~/piscine-go/test$ ./test
[false true true false true false]
