## Chifoumi

### Prerequisite

Create a file `ChifoumiAction.java` and paste the following code inside it:

```java
public enum ChifoumiAction {
    ROCK, PAPER, SCISSOR
}
```

### Instructions

Create a file `Chifoumi.java`.

Write a function `getActionBeatenBy` which takes an action as a parameter, and returns the action which is beaten by the argument.

The actions:

- `ROCK` will return `SCISSOR`
- `PAPER` will return `ROCK`
- `SCISSOR` will return `PAPER`

Use the `switch` operator.

### Expected Functions

```java
public class Chifoumi {
    public static ChifoumiAction getActionBeatenBy(ChifoumiAction chifoumiAction) {
        // your code here
    }
}
```

### Usage

Here is a possible ExerciseRunner.java to test your function :

```java
public class ExerciseRunner {
    public static void main(String[] args) {
        System.out.println(Chifoumi.getActionBeatenBy(ChifoumiAction.ROCK));
        System.out.println(Chifoumi.getActionBeatenBy(ChifoumiAction.PAPER));
        System.out.println(Chifoumi.getActionBeatenBy(ChifoumiAction.SCISSOR));
    }
}
```

and its output :

```shell
$ javac *.java -d build
$ java -cp build ExerciseRunner
SCISSOR
ROCK
PAPER
$
```
