======Project: SLL2======

=====Errata=====
This section will document any updates applied to the project since original release:

  * __revision 1__: In anticipation for the release of our next project (**dll0**), I have made some tweaks to the base Makefile to allow for a smoother transition at project upgrade time. (20141026)
  * __revision 2__: Typo in my original tweak preventing it from working. Now that I've tested it, we have a working solution, and dll0 can now be properly upgraded to... be sure to update before upgrading! (20141027)
  * __revision 3__: Typo with for loop iterations (one too many) in unit-sortlist... now fixed. It makes a backup copy of the original, should any additional local changes have been made. (20141028)
  * __revision 4__: Base Makefile aesthetic enhancements (20141103)

=====Objective=====
In this project, we wrap up our singly-linked list implementation by exploring the reverse display and sorting of nodes in a list, along with writing a few application programs to see our list in action.

=====Project Overview=====

For this project, we're going to be implementing the following functions:

<code c>
List *sortlist(List *, int);  // sort list (according to mode)
void  displayb(List *, int);  // display list in reverse order
</code>

====list library====
In **src/list/**, you will find 2 new C files:

  * **sort.c**     - which will house the list sort function
  * **displayb.c** - which will handle displaying the list backwards

Take a look at the code there. These are the files that contain functions which will be compiled and archived into the node library (**liblist.a**) we will be using in this and future projects.

Figure out what is going on, make sure you understand it.

====List library unit tests====
In **testing/list/unit/**, you will find these new files:

  * **unit-sortlist.c** - unit test for **sortlist()** library function
  * **unit-displayb.c** - unit test for **displayb()** library function

These are complete runnable programs (when compiled, and linked against the list library, which is all handled for you by the **Makefile** system in place).

Of particular importance, I want you to take a close look at:

  * the source code to each of these unit tests
    * the purpose of these programs is to validate the correct functionality of the respective library functions
    * follow the logic
    * make sure you understand what is going on
    * ask questions to get clarification!
  * the output from these programs once compiled and ran
    * analyze the output
    * make sure you understand what is going on
    * ask questions to get clarification!

====list testing applications====

===palindrome===
Now that we've completed our list functionality, we can use these individual functions to piece together solutions to various everyday problems where a list could be effective. After all, that's a big aspect to learning data structures- they open doors to new algorithms and problem solving capabilities.

Our first endeavor will be that of palindromes (ie words/phrases that, when reversed, spell the same thing).

This implementation will be considered an extra credit opportunity, so as to offer those who have fallen behind (but working to get caught up) a reprieve on some of the credit they've lost.

It is also highly recommended to undertake as it will give you further experience working with these concepts.
=====Submission Criteria=====
To be successful in this project, the following criteria must be met:

  * Project must be submit on time, by the posted deadline.
    * The late submission window, if any, will be far shorter and once closed, will see no project evaluations done.
  * Code must compile cleanly (no warnings or errors)
    * all requested functions must be implemented in the related library
    * all requested functionality must conform to stated requirements (either on this project page or in comment banner in source code files themselves).
  * Executed programs must display in a manner similar to provided output
    * output formatted, where applicable, must match that of project requirements
  * Processing must be correct based on input given and output requested
  * Output must be correct (i.e. the list visualization, where applicable) based on values input
  * Code must be nicely and consistently indented (you may use the **indent** tool)
  * Code must be commented
    * Any "to be implemented" comments **MUST** be removed
    * Sufficient comments explaining the point of provided logic **MUST** be present
  * Track/version the source code in a repository
  * Submit a copy of your source code to me using the **submit** tool (**make submit** will do this) by the deadline.
