Scala Get First and Last elements of List using Pattern Matching

Question

I am doing a pattern matching on a list. Is there anyway I can access the first and last element of the list to compare?

I want to do something like..

Answer 1

simply:

case head +: _ :+ last => 

for example:

scala> val items = Seq("ham", "spam", "eggs")
items: Seq[String] = List(ham, spam, eggs)

scala> items match {
     |   case head +: _ :+ last => Some((head, last))
     |   case List(head) => Some((head, head))
     |   case _ => None
     | }
res0: Option[(String, String)] = Some((ham,eggs))
