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)

object Main {
    def main(args : Array[String]) : Unit = {
        val a = io.StdIn.readLine().split(" ").map(_.toInt)
        println(if (a(0) < a(1) && a(1) < a(2)) "Yes" else "No")
    }
}
