        int[] tempArray = new int[array.Length];
        array.CopyTo(tempArray, 0);

        for (int i = 0; i < array.Length - index; i++)
        {
            array[index + i] = tempArray[i];
        }

        for (int i = 0; i < index; i++)
        {
            array[i] = tempArray[array.Length -1 - i];
        }
