Link Nodes Practice Exercises
=============================

createList
----------

.. extrtoolembed:: 'createList'
   :module: Links2
   :long_name: createList
   :learning_tool: code-workout
   :launch_url: https://opendsa-server.cs.vt.edu/lti/launch_extrtool/192900
   :id: 114835



One can easily write a loop to iterate through all the Links on a
chain, without needing to know how many there actually are.

.. inlineav:: linkNodes3CON ss
   :output: show


iterateOverList
---------------
.. extrtoolembed:: 'iterateOverList'
   :module: Links2
   :long_name: iterateOverList
   :learning_tool: code-workout
   :launch_url: https://opendsa-server.cs.vt.edu/lti/launch_extrtool/192901
   :id: 114836



One can remove a Link from a chain.

.. inlineav:: linkNodes4CON ss
   :output: show


changePointeeNext1
------------------

.. extrtoolembed:: 'changePointeeNext1'
   :module: Links2
   :long_name: changePointeeNext1
   :learning_tool: code-workout
   :launch_url: https://opendsa-server.cs.vt.edu/lti/launch_extrtool/192902
   :id: 114837




Finally, we can also insert new Links.

.. inlineav:: linkNodes5CON ss
   :output: show


addNodeAtHead
-------------

.. extrtoolembed:: 'addNodeAtHead'
   :module: Links2
   :long_name: addNodeAtHead
   :learning_tool: code-workout
   :launch_url: https://opendsa-server.cs.vt.edu/lti/launch_extrtool/192903
   :id: 114838
