Solution in C# (judge verdict: Accepted)

using System;
using System.Linq;

class P
{
  static void Main()
  {
    var a = Console.ReadLine()
            .Split(' ')
            .Select(x => int.Parse(x))
            .ToList();
    if(a[0] < a[1] && a[1] < a[2]) {
      Console.WriteLine("Yes");
    } else {
      Console.WriteLine("No");
    }
  }
