Input

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

Output

Sample Output 2

No

Solution in Scala (judge verdict: Accepted)

import java.util.Scanner

object Main {
  def main (args: Array[String]) = {
    val in = new Scanner(System.in)
    val a = in.nextInt()
    val b = in.nextInt()
    val c = in.nextInt()
    val result = if (a < b && b < c) "Yes" else "No"

    println(result)
  }
}
