ScalaのStreamで書いたFizzBuzz

FizzBuzz.scala

def fizzbuzz(table: Seq[(Int, String)])(i: Int): String = {
  val s = table.map { case (num, mes) =>
    if (i % num == 0) mes else ""
  }.mkString("")
  (if (s.isEmpty) i.toString else s)
}

def fizzbuzzStream(table: Seq[(Int, String)]): Stream[String] =
  Stream.from(1).map(fizzbuzz(table)(_))

object FizzBuzz extends App {
  val t = Seq((3, "Fizz"), (5, "Buzz"))
  println(fizzbuzzStream(t).take(100).mkString(" "))

  // val fb = fizzbuzz(Seq((3, "Fizz"), (5, "Buzz")))_
  // println((1 to 10).map(fb).mkString(" "))
