## SortArgs

### Instructions

Create a file named `SortArgs.java`.

Write a function `sort` that sorts the given array specified in the parameters and print the sorted array into the standard ouput. The elements should be separated by spaces with a new line at the end. All the given elements are correct numbers.


### Expected Functions

```java
public class SortArgs {
    public static void sort(String[] args) {
        // your code here
    }
}
```

### Usage

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

```java
import java.io.*;

public class ExerciseRunner {
    public static void main(String[] args) throws IOException {
        ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
        PrintStream printStream = new PrintStream(outputStream);
        System.setOut(printStream);
        SortArgs.sort(new String[]{"4","2","1","3"});
        String output = outputStream.toString();
        System.out.println(output.equals("1 2 3 4\n"));
    }
}
```

and its output :

```shell
$ javac *.java -d build
$ java -cp build ExerciseRunner
true
$
```
