This is my C# sharp code.

        string[] s1 = Console.ReadLine().Split(' ');
        int n = int.Parse(s1[0]);
        int k = int.Parse(s1[1]);

        string[] s = Console.ReadLine().Split(' ');
        int[] array = new int[n];

        ////pre-rotation of array method:
        //-----------------------------------Right rotation
        //for (int i = 0; i < n; i++)
        //{
        //    array[(i + k) % n] = int.Parse(s[i]);
        //}

        //------------------------------------Left rotation
        for (int i = 0; i < n; i++)
        {
            array[(i + (n-k)) % n] = int.Parse(s[i]);
        }

        for (int i = 0; i < n; i++)
        {
            Console.WriteLine(array[i]+" ");
        }
