Solution in C# (judge verdict: Accepted)

using System;

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