## foreach
##**WARNING! VERY IMPORTANT!**
For this exercise a function will be tested **with the exam own main**. However the student **still needs** to submit a structured program:
This means that:
- The package needs to be named `package main`.
- The submitted code needs one declared function main(```func main()```) even if empty.
- The function main declared needs to **also pass** the `Restrictions Checker`(illegal functions tester). It is advised for the student to just empty the function main after its own testings are done.
- Every other rules are obviously the same than for a `program`.
### Instructions
Write a function `ForEach` that, for an `int` array, applies a function on each elements of that array.
### Expected function
```go
func ForEach(f func(int), arr []int) {
}
```
### Usage
Here is a possible [program](TODO-LINK) to test your function :
```go
package main
func main() {
arr := []int{1, 2, 3, 4, 5, 6}
ForEach(PrintNbr, arr)
}
func PrintNbr(int) {
}
```
And its output :
```console
student@ubuntu:~/test$ go build
student@ubuntu:~/test$ ./test
123456
student@ubuntu:~/test$
```
