A - Median? Editorial by en_translator
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")
