<p><b>NOTE: This project is divided into two parts (Part I and
Part II). For the Programming Exam you only need to complete
Part I. Part II will be completed after the Programming
Exam.</b></p>
<h3>Overview</h3>
<p>Most non-trivial programs use data structures to store and
access information. Common examples are lists, stacks, queues,
trees, etc. Data structures are also called "collections"
because they are used to manage groups (or collections) of
objects. For this assignment you will write two collection
classes in C++. You will write a class named
<tt>LinkedList</tt> that implements a doubly-linked list and a
class named <tt>BST</tt> that implements a binary search tree.
Unlike the previous projects, you will not be asked to deliver
a complete running program. Rather, the deliverables for this
project are just the <tt>LinkedList</tt> and <tt>BST</tt>
classes. To pass off your project, we will take your classes
and compile and link them with a test program that will
exercise your code and verify that it works. It is your
responsibility to test your code and make sure that it works
before passing off.</p>
<h3>Project Files</h3>
<p>Header files for the <tt>LinkedList</tt> and <tt>BST</tt>
classes are provided at the following links:</p>
<p><a href="http://students.cs.byu.edu/%7Ecs240ta/winter2008/projects/collections/LinkedList.h">LinkedList.h</a></p>
<p><a href="http://students.cs.byu.edu/%7Ecs240ta/winter2008/projects/collections/BST.h">BST.h</a></p>
<p>Your task is to implement all of the methods on the
<span style="font-family: "Courier New";">LinkedList</span> and
<span style="font-family: "Courier New";">BST</span> classes
according to the comments in the header files. You should place
your <span style="font-family: "Courier New";">LinkedList</span>
and <span style="font-family: "Courier New";">BST</span>
implementations in files named <span style="font-family: "Courier New";">LinkedList.cpp</span> and
<span style="font-family: "Courier New";">BST.cpp</span>,
respectively. You should not modify the public interfaces of
the classes. If you do, the test program that will be used to
pass off your code will not compile. You may (and probably
should) modify the <span style="font-family: "Courier New";">.h</span> files to add private
method and variable declarations, but your method bodies should
go in the <span style="font-family: "Courier New";">.cpp</span>
files.</p>
<p>The test program will assume that your files are named
<span style="font-family: "Courier New";">LinkedList.h</span>,
<span style="font-family: "Courier New";">LinkedList.cpp</span>,
<span style="font-family: "Courier New";">BST.h</span>, and
<span style="font-family: "Courier New";">BST.cpp</span> Since
Linux file names are case sensitive, capitalization does
matter.</p>
<h3>Restrictions</h3>
<p>For this project you <u>are</u> allowed to use the C++
string class defined in the <span style="font-family: "Courier New";"><string></span> header file
(in fact, you must use it to make your code work).</p>
<p>You <u>are not</u> allowed to use the classes and functions
from the Standard Template Library (vector, list, map, set,
etc.). Specifically, the following header files may not be
used:</p>
<ul>
<li><algorithm></li>
<li><deque></li>
<li><list></li>
<li><map></li>
<li><queue></li>
<li><set></li>
<li><stack></li>
<li><vector></li>
</ul>
<h3>Part I</h3>
<p>Implement all of the methods on the <span style="font-family: "Courier New";">LinkedList</span> and <span style="font-family: "Courier New";">BST</span> classes.</p>
<p>For Part I your code will not be tested for memory
management errors. That will come in Part II.</p>
<h3>Part II</h3>
<p>Ensure that your code does not contain any memory management
errors, as described in the <i>Memory Management Errors</i>
section of the Project I specification. The TAs will use
<span style="font-family: "Courier New";">valgrind</span> to
check your code for memory-related errors when you pass off.
You should run <span style="font-family: "Courier New";">valgrind</span> on your code and
fix any reported bugs before attempting to pass off.</p>
<p>Not all memory errors are your fault and there are cases of false positives. We offer a <a href="http://students.cs.byu.edu/%7Ecs240ta/util_docs/string.supp">file</a> to suppress these for you.</p>
