Problem:
Range

Write a program which reads three integers a, b and c, and prints "Yes" if a < b < c, otherwise "No".

Input

Three integers a, b and c separated by a single space are given in a line.

Output

Print "Yes" or "No" in a line.

Constraints

0 ≤ a, b, c ≤ 100

Sample Input 1

1 3 8

Sample Output 1

Yes

Sample Input 2

3 8 1

Sample Output 2

No

Solution in Scala (judge verdict: Accepted)

import scala.io.StdIn

object Main {
  def main(args:Array[String]):Unit = {
    val in = StdIn.readLine().split(" ").map(s => s.toInt)

    if (in(0) < in(1) && in(1) < in(2)) {
      println("Yes")
    } else {
      println("No")
    }
  }
}
