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

Solution in Scala (2.11.7) (judge verdict: Accepted)

import java.util.Scanner

object Main {
  def read() = {
    val sc = new Scanner(System.in)
    val a, b, c = sc.nextInt()

    //val h = for (_ <- 0 until n) yield sc.nextInt()
    (a, b, c)
  }

  def solve(n: Int): Int = {
    0
  }


  def main(args: Array[String]): Unit = {
    val (a, b, c) = read()
    if ((a < c && c < b) ||(b < c && c < a)) {
      println("Yes")
    } else {
      println("No")
    }
  }
