MList notes

MList-- kinda like SList except the parameters are vars instead of vals, so the list is mutable

case class MList(var item, var next: MList)

The MList is basically the same except the header node contains the size of the list which is different.

======

def take(list: MList, n: Int): Unit {

}

(5,1,2,3,4,5) take 3
5,1  D  (2,3,4,5)
list.item,list.next.item | list.next.next
(3,1,2,3)
