Solution in Scala (2.11.7) (judge verdict: Accepted)

import scala.io._

// e.g
// 1 2 3
// val Array(a, b) = readLine.split(" ").map(_.toInt) => Array(1, 2, 3)
// 5
// 1 2 3
// 4 5 6
// 7 8 9
// val lines = Source.stdin.getLines()
// データ個数読み取り
// val n = lines.next().toInt
// データ行n個読み取り
// val data = lines.take(n).map{ line => line.split(" ").map(_.toInt).toList }.toList => List(List(1, 2, 3), List(4, 5, 6), List(7, b, 9))

object Main {
  def main(args: Array[String]): Unit = {
    val s: String = readLine
    if (s(1) == '9' || s(0) == '9') {
      println("Yes")
    }else {
      println("No")
    }

  }
