Answer 1

import scala.concurrent.duration._
import scala.concurrent.{Await, Future}
import scala.concurrent.ExecutionContext.Implicits.global

object CountdownApp extends App {
  def countdown(seconds: Int): Unit = {
    println(s"Total time: $seconds seconds")

    var remaining = seconds
    while (remaining > 0) {
      Thread.sleep(1000) // Sleep for 1 second
      remaining -= 1
      println(s"Time remaining: $remaining seconds")
    }
  }

  val sec = 5
  
  countdown(sec)
}
