Solution in C# (judge verdict: Accepted)

using System;
using System.Linq;

namespace _1_2_B {
    class Program {
        static void Main(string[] args)
        {
            var input = Console.ReadLine();
            var array = input.Split(' ').Select(x => int.Parse(x)).ToArray();
            if (array[0] < array[1] && array[1] < array[2])
                Console.WriteLine("Yes");
            else
                Console.WriteLine("No");
        }
    }
}
