问在scala中读取多行作为输入

EN

// default condition: string is not empty, not inclusive! 
class TermLines (cond: (String => Boolean) = _ != "") extends Iterator[String] { 
  var s = readLine; 
  def hasNext = cond(s); 
  def next = { var r = s; s = readLine; r } 
} 

println((new TermLines).toVector.mkString("\n")) // till empty

println(new TermLines(_.last != '.').toVector.mkString("\n")) // till last is dot

import scala.io.StdIn

object Solution extends App
{
    val numOfLines = StdIn.readInt()
    def words: Seq[String] = for (_ <- 1 to numOfLines) yield StdIn.readLine()
    def sort = words.map
    {
        case word => word
    }
    sort.foreach(println)
}
