Practice Together

Together we will

• talk about native arrays vs. Ruby arrays (ArrayList in Java)
• write lib/array_list.rb where we will simulate what happens "under the hood" with Ruby's Array object.
  • together: initialize, add, delete, to_s, include?, size
  • on your own: max
• Then we will take a look at lib/linked_list.rb and see how the implementation is different (but the interface is the same) and uses nodes instead of a native array to store data.
  • provided: Node class, LinkedList class: initialize, add, delete, to_s
  • together: include?
  • on your own: size, max
