## foreach
|
||
|
|
|
||
|
|
### Instructions
|
||
|
|
|
||
|
|
Write a function `ForEach` that, for an `int` slice, applies a function on each element of that slice.
|
||
|
|
|
||
|
|
### Expected function
|
||
|
|
|
||
|
|
```go
|
||
|
|
func ForEach(f func(int), a []int) {
|
||
|
|
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
### Usage
|
||
|
|
|
||
|
|
Here is a possible program to test your function :
|
||
|
|
|
||
|
|
```go
|
||
|
|
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 :
|
||
|
|
|
||
|
|
```console
|
||
|
|
$ go run .
|
||
|
|
123456
|
||
|
|
$
|
||
|
|
```
|
||
|
