Beginning Java Data Structures and Algorithms

By: Kristian Secor

Overview of this book

Learning about data structures and algorithms gives you better insight on how to solve common programming problems. Most of the problems faced every day by programmers have been solved, tried, and tested. By knowing how these solutions work, you can ensure that you choose the right tool when you face these problems. This course teaches you tools that you can use to build efficient applications. It starts with an introduction to algorithms and big O notation, later explains bubble, merge, quicksort, and other popular programming patterns. You'll also learn about data structures such as binary trees, hash tables, and graphs. The course progresses to advanced concepts, such as algorithm design paradigms and graph theory. By the end of the course, you will know how to correctly implement common algorithms and data structures within your applications.

Getting Started with the Boyer-Moore String Searching Algorithm
The Boyer-Moore string searching algorithm was introduced by Robert S. Boyer and J. Strother Moore in 1977, and builds upon the naive search algorithm by intelligently skipping certain sections of the text. One key feature of the algorithm is that it matches the pattern from right to left, instead of left to right, using to its advantage a couple of shift rules that improve its running time. To understand the effect of these rules, let's build the Boyer-Moore algorithm from our naive search algorithm.
