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]): Unit = {
    val a = readLine.split(" ").map(_.toInt)
    var f = "No"
    if(a(0) < a(1) && a(1) < a(2)) {
      f = "Yes"
    }
    printf("%s\n", f)
  }
}
