Answer 1

object SeqAccessElements   {
  def main(args: Array[String]): Unit = {
    val seq = Seq(321, 90, 89, 10, 17)

    val element = seq(2) // Accesses the third element
    println(element) 

    // Retrieves the first element and the rest of the sequence.
    val first = seq.head 
    println(first) 
    
    val rest = seq.tail 
    println(rest) 

    // Retrieves the last element.
    val lastElement = seq.last 
    println(lastElement) 
  }
}
