map

Instructions

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

Expected function

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

}

Usage

Here is a possible program to test your function :

package main

import (
	"fmt"
	"piscine"
)

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

And its output :

$ go run .
[false true true false true false]
$
