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 input: String = readLine()
    val list: Array[String] = input.split(" ")
    
    val a: Int = list(0).toInt
    val b: Int = list(1).toInt
    val c: Int = list(2).toInt

    var ans = "No"
    if (a < b && b < c) {
      ans = "Yes"
    }
    println(ans)
  }
  
//  def readLine(): String = {"5 5"}
}
