This fourth edition of Robert Sedgewick and Kevin Wayne’s Algorithms is the leading textbook on algorithms today and is widely used in colleges and universities worldwide. This book surveys the most important computer algorithms currently in use and provides a full treatment of data structures and algorithms for sorting, searching, graph processing, and string processing--including fifty algorithms every programmer should know. In this edition, new Java implementations are written in an accessible modular programming style, where all of the code is exposed to the reader and ready to use.

 

The algorithms in this book represent a body of knowledge developed over the last 50 years that has become indispensable, not just for professional programmers and computer science students but for any student with interests in science, mathematics, and engineering, not to mention students who use computation in the liberal arts.

 

The companion web site, algs4.cs.princeton.edu, contains

  • An online synopsis
  • Full Java implementations
  • Test data
  • Exercises and answers
  • Dynamic visualizations
  • Lecture slides
  • Programming assignments with checklists

The MOOC related to this book is accessible via the "Online Course" link at algs4.cs.princeton.edu. The course offers more than 100 video lecture segments that are integrated with the text, extensive online assessments, and the large-scale discussion forums that have proven so valuable. Offered each fall and spring, this course regularly attracts tens of thousands of registrants.

 

Robert Sedgewick and Kevin Wayne are developing a modern approach to disseminating knowledge that fully embraces technology, enabling people all around the world to discover new ways of learning and teaching. By integrating their textbook, online content, and MOOC, all at the state of the art, they have built a unique resource that greatly expands the breadth and depth of the educational experience.

by creating a library of static methods, one of which is named main(). Typing java followed by a class name followed by a sequence of strings leads to a call on main() in that class, with an array containing those strings as argument. After the last statement in main() executes, the program terminates. In this book, when we talk of a Java program for accomplishing a task, we are talking about code developed along these lines (possibly also including a data-type definition, as described in Section

track of fundamental operations when analyzing the performance of algorithms. To use a Counter, you need to learn our mechanism for specifying the operations defined in the data type and the Java language mechanisms for creating and manipulating data-type values. Such mechanisms are critically important in modern programming, and we use them throughout this book, so this first example is worthy of careful attention. API for an abstract data type. To specify the behavior of an abstract data type,

on the facing page defines an abstract data type that provides to clients the ability to maintain a running average of data values. For example, we use this data type frequently in this book to process experimental results (see Section 1.4). The implementation is straightforward: it maintains a int instance variable counts the number of data values seen so far and a double instance variable that keeps track of the sum of the values seen so far; to compute the average it divides the sum by the

a boolean value is known as a boolean expression. Such expressions are essential components in conditional and loop statements, as we will see. Other primitive types. Java’s int has 232 different values by design, so it can be represented in a 32-bit machine word (many machines have 64-bit words nowadays, but the 32-bit int persists). Similarly, the double standard specifies a 64-bit representation. These data-type sizes are adequate for typical applications that use integers and real numbers. To

Calls and returns relate to static methods (see page 22), which provide another way to change the flow of execution and to organize code. A program is a sequence of statements, with declarations, assignments, conditionals, loops, calls, and returns. Programs typically have a nested structure : a statement among the statements in a block within a conditional or a loop may itself be a conditional or a loop. For example, the while loop in rank() contains an if statement. Next, we consider each of
