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

Sample Output 2

No

Solution in Scala (judge verdict: Accepted)

import scala.io.StdIn

/**
  * AOJ
  */
object Main {

  def main(args: Array[String]): Unit = {

    val in = StdIn.readLine().split(" ").map(s => s.toInt)

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