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

Solution in Rust (1.15.1) (judge verdict: Accepted)

fn read<T: ::std::str::FromStr>() -> T {
    let mut s = String::new();
    ::std::io::stdin().read_line(&mut s).ok();
    s.trim().parse().ok().unwrap()
}

fn read_vec<T: ::std::str::FromStr>() -> Vec<T> {
    let mut s = String::new();
    ::std::io::stdin().read_line(&mut s).ok();
    s.trim().split_whitespace()
        .map(|e| e.parse().ok().unwrap()).collect()
}

pub fn main() {
    let ABC = read_vec();
    let A: i32 = ABC[0];
    let B: i32 = ABC[1];
    let C: i32 = ABC[2];
    if (A <= C && B >= C) || (A >= C && B <= C) {
        println!("Yes");
    } else {
        println!("No");
    }
}
