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 extends App {
	override def main(args: Array[String]) = {
		val sc = new java.util.Scanner(System.in);
		val a,b,c = sc.nextInt();
		
		val res = solve(a,b,c);
		println(res);
		
	}
	
	def solve(a:Int,b:Int,c:Int):String = {
		(a,b,c) match{
			case (x:Int , y:Int, z:Int) if x < y && y < z =>
				"Yes"
			case _ =>
				"No"
		} 
	}
