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 in = readLine.split(" ").map(_.toInt)
		val a = in(0)
		val b = in(1)
		val c = in(2)
		
		if( a < b && b < c) {
			println("Yes")
		} else {
			println("No")
		}
	}
}
