Slightly better version of FizzBuzz

FizzBuzzV2.scala

object Main extends App {
  val source = scala.io.Source.fromFile(args(0))
  source.getLines
    	.filter(_.length > 0)
  		.map(_.split(" ").map(_.toInt))
  		.map(x => fizz(x(0), x(1), x(2)))
  		.foreach(println)

  def fizz(a:Int, b:Int, n:Int) = {
  	def buzz(check:Int, fizz:Int, buzz:Int) = {
  		val f = check % fizz == 0
  		val b = check % buzz == 0
  		if(f && b) "FB"
  		else if(f) "F"
  		else if(b) "B"
  		else check.toString
  	}
  	1 to n map(x => buzz(x, a, b))
  }
}
