Score : 100 points

Problem Statement

There are three houses on a number line: House 1, 2 and 3, with coordinates A, B and C, respectively.
Print Yes if we pass the coordinate of House 3 on the straight way from House 1 to House 2 without making a detour, and print No otherwise.

Constraints

0\leq A,B,C\leq 100

A, B and C are distinct integers.

Input

Input is given from Standard Input in the following format:

A B C

Output

Print Yes if we pass the coordinate of House 3 on the straight way from House 1 to House 2 without making a detour, and print No otherwise.

Sample Input 1

3 8 5

Sample Output 1

7 3 1

Sample Output 2

No

Sample Input 3

10 2 4

Sample Output 3

Yes

Sample Input 4

Solution in C# (Mono 4.6.2.0) (judge verdict: Wrong Answer)

using System;

public class Program
{
    public static void Main()
    {
        string[]array=Console.ReadLine().Split(' ');
        var num1=int.Parse(array[0]);
        var num2=int.Parse(array[1]);
        var num3=int.Parse(array[2]);
        
        if(num2>num1&&num2>num3)Console.WriteLine("Yes");
        else if(num2<num1&&num2<num3)Console.WriteLine("Yes");
        else Console.WriteLine("No");
        
    }
}
