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

No

Solution in C# (Mono 4.6.2.0) (judge verdict: Accepted)

using System;
using System.Collections.Generic;
public class Tebka1Begginer2019A {
    public static void Main() {
        int A, B, C;
        string[] str = System.Console.ReadLine().Split(' ');
        A = int.Parse(str[0]);
        B = int.Parse(str[1]);
        C = int.Parse(str[2]);

        if (A < C && C < B) {
            System.Console.WriteLine("Yes");
        } else if (A > C && C > B) {
            System.Console.WriteLine("Yes");
        } else {
            System.Console.WriteLine("No");
        }
    }
