Rotate an Array to the Right.

Write a method to rotate an input array by n positions to the right.

Assume that n < size of the array.

Example:



Input Array : {1, 2, 3, 4, 5, 6, 7, 8}  
Input n     : 2
Output      : {7, 8, 1, 2, 3, 4, 5, 6}

The key here is to take the last n elements and add them to the beginning. This can be done in following steps.

1. Copy last n elements to a temporary array.

2. Shift all the elements in an input array to the right by n positions.

3. Insert all the elements from the temporary array to the beginning of the input array.

public static int[] rotate(int[] a, int m)
    {
        



        
    }
