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<bits/stdc++.h>
using namespace std;

int main(){
    int a,b,c;
    cin>>a>>b>>c;
    bool ok;
    if(a<=c){
        if(a<=b && b<=c) ok=true;
        else ok=false;
    }
    if(a>=c){
        if(a>=b && b>=c) ok=true;
        else ok=false; 
    }
    if(ok)cout<<"Yes"<<endl;
    else cout<<"No"<<endl;
