Write a program in Scala that computes the mean of quiz and assignment grades where you have the following defined classes

// simple Scala classes

sealed abstract class Component

case class Quiz (grade:Int) extends Component

// using these classes you can instanciate object lists

val quizzes = List(Quiz(10), Quiz(20), Quiz(30))

// now you can define functions that would work on these lists

def quizMean (l:List[Quiz]):Double = {}

println(quizMean( quizzes))
