Solution in C# (judge verdict: Accepted)

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace Range
{
    class Program
    {
        static void Main(string[] args)
        {
            int a, b, c;
            string[] str = Console.ReadLine().Split(' ');
            a = int.Parse(str[0]);
            b = int.Parse(str[1]);
            c = int.Parse(str[2]);

            if (a < b && b < c)
                Console.WriteLine("Yes");
            else
                Console.WriteLine("No");
        }
    }
