Solution in C# (judge verdict: Accepted)

using System;
using System.Linq;

namespace paizaTest
{
    internal class Program
    {
        private static void Main(string[] args)
        {
            var readLine = Console.ReadLine().Split(' ').Select(int.Parse).ToList();
            var resultFlag = true;
            for (var i = 0; i < readLine.Count() - 1; i++)
            {
                if (readLine[i] >= readLine[i + 1])
                {
                    resultFlag = false;
                }
            }

            Console.WriteLine(resultFlag ? "Yes" : "No");
        }
    }
