Solution in C# (judge verdict: Accepted)

using System;

namespace _2_B
{
    class Program
    {
        static void Main(string[] args)
        {
            var abc = Array.ConvertAll(Console.ReadLine().Split(' '), int.Parse);
            var a = abc[0];
            var b = abc[1];
            var c = abc[2];
            if (a < b && b < c)
            {
                Console.WriteLine("Yes");
            }
            else
            {
                Console.WriteLine("No");
            }
        }
    }
