In this tutorial for VisualBasic.NET programmers, data structures and algorithms are presented as problem-solving tools that do not require translations from C++ or Java. McMillan (computer information systems, Pulaski Technical College) explains arrays, ArrayLists, linked lists, hash tables, dictionaries, trees, graphs, and sorting and searching with object-oriented representations. He is consistently practical, using, for example, timing tests rather than Big O analysis to compare the performance of data structures and algorithms.
