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

Yes

We pass the coordinate 5 on the straight way from the house at coordinate 3 to the house at coordinate 8.

Sample Input 2

7 3 1

Sample Output 2

No

Sample Input 3

10 2 4

Sample Output 3

Yes

Sample Input 4

31 41 59

Sample Output 4

No

using System;

using System.Collections.Generic;
using System.Linq;

class myon
{
    public static void Main(string[] args)
    {
        var myon = new myon();
    }

    public myon()
    {
        string[] input = Console.ReadLine().Split(' ');

        int[] intin = new int[3];
        for (int i = 0; i < 3; i++)
        {
            intin[i] = int.Parse(input[i]);
        }

        if (intin[0] < intin[1] && intin[0] < intin[2] && intin[1] > intin[2]) Console.WriteLine("Yes");
        else if (intin[1] < intin[0] && intin[1] < intin[2] && intin[0] > intin[2]) Console.WriteLine("Yes");
        else Console.WriteLine("No");
    }
