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