        for (int i = 0; i < arr.Length; i++) {
            for (int j = 0; j < arr[i].Length; j++) {
                Console.Write($"{arr[i][j]}\t");
            }
            Console.Write("\n");
        }
    }
    static void Main() {
        int[][] arr = new int[2][];

        arr[0] = new int[]{1, 9, 7, 8, 0};
        arr[1] = new int[4];

        arr[1][0] = 8;
        arr[1][1] = 2;
        arr[1][2] = 6;
        arr[1][3] = 5;

        Display(arr);
    }
}
