Solution in C# (judge verdict: Accepted)

using System;
using System.Collections.Generic;
/*using System.Linq;
using System.Text;
using System.Threading.Tasks;*/
class Program
{
    static void Main(string[] args)
    {
        String s = Console.ReadLine();
        String[] sarray = s.Split(' ');          //?????????????????????????´?

        int a = int.Parse(sarray[0]);
        int b = int.Parse(sarray[1]);
        int c = int.Parse(sarray[2]);
                                                 //a??¨b??¨c???????´?????????????
        if (a <b && b < c)
        {
            Console.WriteLine("Yes");
        }
        else
        {
            Console.WriteLine("No");
        }

    }
