func Map(f func(int) bool, a []int) []bool {
}
```
### Usage
Here is a possible program to test your function :
```go
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 :
```console
student@ubuntu:~/[[ROOT]]/test$ go build
student@ubuntu:~/[[ROOT]]/test$ ./test
[false true true false true false]
student@ubuntu:~/[[ROOT]]/test$
```
