Input

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

Output

No

Solution in Scala (judge verdict: Accepted)

object Main {
  def main(args: Array[String]) {
    val s = io.StdIn.readLine().split(" ") map (i => Integer.parseInt(i))
    println("%s".format(if (s(0)<s(1) && s(1)<s(2)) "Yes" else "No"))
  }
}
