Solution in C# (judge verdict: Accepted)

using System;
using System.Linq;

namespace Range
{
    class Program
    {

        static void Main(string[] args)
        {
            int[] i = Console.ReadLine().Split(' ')
                    .Select(e => int.Parse(e)).ToArray();
            
            int a = i[0];
            int b = i[1];
            int c = i[2];

            Console.WriteLine(a < b && b < c ? "Yes" : "No");
        }
    }
}
