Solution in C# (judge verdict: Accepted)

using System;
class Program
{
    public static void Main()
    {
        int[] t = Array.ConvertAll(System.Console.ReadLine().Split(' '),int.Parse);
        int a = t[0]; 
        int b = t[1];
        int c = t[2];
        string s;
        
        if(a < b && b < c)
            s = "Yes";
        else
            s = "No";
        
        System.Console.WriteLine("{0}",s);
    }
}
