Solution in C# (judge verdict: Accepted)

using System;

public class SmallOrLarge
{
    //?????????????????§?°????????????????
    static void Main(string[] args)
    {
        /*---??£?¨???¨---*/
        int num1;
        int num2;
        int num3;
        string[] num_unit;
        /*---??£?¨???¨---*/

        /*??°???????????????????????§??????*/
        num_unit = Console.ReadLine().Split(' ');
        num1 = int.Parse(num_unit[0]);
        num2 = int.Parse(num_unit[1]);
        num3 = int.Parse(num_unit[2]);

        /*???????????????????????????[a<b<c]??????Yes*/
        if (num1 < num2 && num2 < num3){
            Console.WriteLine("Yes");
        }
        else{
            Console.WriteLine("No");
        }

    }
