Extracting a Column from a 2D Array

Question

Consider the following client code and method:

```java
int[][] grid = {{5,5,5},{10,10,10},{15,15,15}};
int[] arr = mystery(grid, 2);
for (int num : arr)
   System.out.print(num + " ");

public static int[] mystery(int[][] arr, int n)
{
   int[] m = new int[arr.length];
   for (int i = 0; i < arr.length; i++)
      m[i] = arr[i][n];
   return m;
}
```

What will be printed after the code executes?
