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

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

#include <iostream>
#include <math.h>
#include <string>
#include <algorithm>
#include <vector>
	using namespace std;

	int main() {

		int A, B, C;
		cin >> A >> B >> C;

		if (A < C&&C < B) {
			cout << "Yes" << endl;
		}
		else if (A > C&&C > B) {
			cout << "Yes" << endl;
		}
		else{
			cout << "No" << endl;
		}
		return 0;
