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)

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