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]):Unit={
		val input =io.StdIn.readLine split " "
		if(input(0).toInt < input(1).toInt && input(1).toInt < input(2).toInt )
			println("Yes")
		else
			println("No")

	}
}
