It is sufficient to check if \(b\) comes in the second place when \(a, b\), and \(c\) are sorted in the increasing order.

The answer is Yes if \(a \leq b \leq c\) or \(a \geq b \geq c\), and No otherwise.

Sample code (C++):

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

int main() {
    int a, b, c;
    cin >> a >> b >> c;
    if ((a <= b and b <= c) or (a >= b and b >= c)) {
        cout << "Yes\n";
    } else {
        cout << "No\n";
    }
    return 0;
}

Sample code (Python) :

a, b, c = map(int, input().split())
print("Yes" if a <= b <= c or a >= b >= c else "No")
