Use the BSTSkeleton.java file to create a Binary Search Tree with generic types. Notice there is a separate key & value. In many examples the key IS the value. But this isnt always the case. When complete, your BST should have:

  • toString in Node to return the nodes key.
  • toString in BST that handles pre-order, in-order, and postorder via the enumeration at the top.
  • Make all traversals recursive.
  • Do not change the skeleton, only add concrete implementation. This may be subject to change.
