Question

I\'m trying to write a function which will recursively find the largest element in a list of integers. I know how to do this in Java, but can\'t understand how to do this at Sca

Answer 1

You could use pattern matching like that

def max(xs: List[Int]): Int = xs match {
  case Nil => throw new NoSuchElementException("The list is empty")
  case x :: Nil => x
  case x :: tail => x.max(max(tail)) //x.max is Integer's class method
}
