Solution in C# (judge verdict: Accepted)

using System;
using System.Collections.Generic;
namespace ITP1_2_B
{
    class MainClass
    {

        public static List<string[]> getinputdata (){

            List<string[]> list_temp = new List<string[]>();
            string strdata = Console.ReadLine ();

            while (strdata!=null) {

                string[] s_temp = strdata.Split (' ');

                list_temp.Add (s_temp);

                strdata = Console.ReadLine ();

            }

            return list_temp;
        }



        public static void Main (string[] args)
        {
            List<string[]> arr_result = new List<string[]>();
            arr_result = getinputdata ();
        
            int a = int.Parse(arr_result[0][0]);
            int b = int.Parse(arr_result[0][1]);
            int c = int.Parse(arr_result[0][2]);

            if (a < b && b < c)
            {
