Problem:
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 scala.io.StdIn


object Main extends App {

  val Array(a, b, c)  = StdIn.readLine().split(" ").map(_.toInt)

  def solve(A: Int, B: Int, C: Int): String = {
    if (a < c & b > c) {
      "Yes"
    } else if (a > c & b < c) {
      "Yes"
    } else {
      "No"
    }
  }

  println(solve(a, b, c))
}
