Solution in C# (judge verdict: Accepted)

using System;
class aizu{
    public static int Main(){
        int i;
    	int[] n = new int[100];
    	string[] str = new string[100];
    	str = Console.ReadLine().Split(' ');
        for(i=0;i<3;i++)
    	   n[i] = int.Parse(str[i]);
        if(n[0] < n[1] && n[1] < n[2])
            Console.WriteLine("Yes");
        else
            Console.WriteLine("No");
        return 0;
    }
}
