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 sc = new java.util.Scanner(System.in)
    val a = sc.nextInt
    val b = sc.nextInt
    val c = sc.nextInt
    if (isSorted(a, b, c)) println("Yes") else println("No")
  }
  def isSorted(a: Int, b: Int, c: Int) = {
    if (a < b && b < c) true else false
  }
}
