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