object Main {
  def main(args: Array[String]): Unit = {
    val end = 
    var total = 0

    for (number <- 1 to end) {
      total = total + number
    }

    println("end=" + end)
    println("total=" + total)
  }
}

object Main {
  def main(args: Array[String]): Unit = {
    val end = 
    var total = 0

    for (number <- 1 to end) {
      total = total + number
    }

    println("end=" + end)
    println("total=" + total)
  }
}

object Main {

    val end = 
    var total = 0
