Solution in C# (judge verdict: Accepted)

using System;

namespace AizuOnline
{
    class Program
    {
        static void Main()
        {
            string[] nums = Console.ReadLine().Split();
            int a = Int32.Parse(nums[0]);
            int b = Int32.Parse(nums[1]);
            int c = Int32.Parse(nums[2]);
            if (a < b && b < c)
            {
                Console.WriteLine("Yes");
            }
            else
            {
                Console.WriteLine("No");
            }
        }
    }
