Paper Presentation & Seminar On "Linked Lists Concepts"

This document introduces the basic structures and techniques for building linked lists with a mixture of explanations, drawings, sample code, and exercises. The material is useful if you want to understand linked lists or if you want to see a realistic, applied example of pointer-intensive code. A separate document, Linked List Problems (, presents 18 practice problems covering a wide range of difficulty.

Linked lists are useful to study for two reasons. Most obviously, linked lists are a data structure which you may want to use in real programs. Seeing the strengths and weaknesses of linked lists will give you an appreciation of the some of the time, space, and code issues which are useful to thinking about any data structures in general. Somewhat less obviously, linked lists are great way to learn about pointers. In fact, you may never use a linked list in a real program, but you are certain to use lots of pointers. Linked list problems are a nice combination of algorithms and pointer manipulation. Traditionally, linked lists have been the domain where beginning programmers get the practice to really understand pointers.
