Educators and students consider recursion one of the most difficult topics in introductory programming courses. The limited number of recursive examples in the textbooks is not sufficient for most students. This text is designed to help students in CS I or CS II courses to practice writing recursive code in Java. It may be helpful for instructors teaching those courses, as well. For them it can serve as a poll of test examples, or as a base to create projects that include variations of existing methods. The book provides a collection of over 150 recursive examples on integers, arrays, linked lists, linked trees, and graphical examples. Each example includes a problem specified in English, solution at the algorithm level, and recursive code implemented in Java. Graphical examples have also a picture of the outcome that should be drawn in addition to code. Most of examples were given to my students on tests and final exams. The remaining problems are for advanced students who grasped the topic and want to be challenged to do more.

Educators and students consider recursion one of the most difficult topics in introductory programming courses. The limited number of recursive examples in the regular textbooks is not sufficient for most students. This text is designed to help students in CS I or CS II courses to practice writing recursive code in JavaFX. It may be helpful for instructors teaching those courses, as well. For them it can serve as a poll of test examples, or as a base to create projects that include variations of existing methods. The book provides collection of over 150 recursive examples on integers, arrays, linked lists, linked trees, and graphical examples. Each example includes a problem specified in English, solution at the algorithm level, and recursive code implemented in JavaFX. Graphical examples have also the picture of the outcome drawn by application in addition to code. Ninety percent of examples were given to students on tests and final exams. The remaining ten percent of the problems are for advanced students who grasped the topic and want to be challenged to do more. We start to practice recursion by writing code for simple examples which can also be done iteratively in slightly more efficient way. Recursion requires several calls before reaching the base case. Each invocation requires putting the method name and parameters on the activation stack, and upon completion, removing it from the stack when the results are passed back. This approach is chosen to help learners to adjust to new way of solving problems. Writing code recursively requires a paradigm shift from being used to specifying the steps explicitly, in the order how they are performed, to specifying them implicitly. Recursive problems have base case part where we specify code to provide the desired result without calling any sub-problems, and in addition there is recursive step part where we specify how to obtain the result by invoking one or more sub-problems of the same type as the original problem, plus we perform some additional code to combine the sub-problems and produce the result. Recursion is so difficult to learn because each problem has its own way of formulating base case and recursive step. Sometimes there is one base case, sometimes there are ten base cases, sometimes we do nothing in base case and just return from the method. Recursive steps range from one to many, they vary how we express sub-problems, and each time the way to combine the solutions for sub-problems in order to produce result for original problem, is different as well. When learners start by learning to write recursive code for simple examples, their only challenge is to figure out how to formulate the solution for the given problem recursively. Examples are ordered from simpler to more difficult ones. Many problems are analogous to those done before. This spiral approach allows learners to master recursion at their individual pace. Some should do most of the examples, others can skip similar problems and spend more time on harder problems. Chapter devoted to recursive graphical examples is done in JavaFX which is the latest version of Java. Graphics provides additional advantage because drawing shapes on graphical surface provides visualization of steps performed by recursion.Learning recursion on integers, arrays, linked lists, and graphics, facilitates a smooth transition to writing code recursively on more advanced data structures such as trees and graphs.

Recursion is one of the most fundamental concepts in computer science and a key programming technique that allows computations to be carried out repeatedly. Despite the importance of recursion for algorithm design, most programming books do not cover the topic in detail, despite the fact that numerous computer programming professors and researchers in the field of computer science education agree that recursion is difficult for novice students. Introduction to Recursive Programming provides a detailed and comprehensive introduction to recursion. This text will serve as a useful guide for anyone who wants to learn how to think and program recursively, by analyzing a wide variety of computational problems of diverse difficulty. It contains specific chapters on the most common types of recursion (linear, tail, and multiple), as well as on algorithm design paradigms in which recursion is prevalent (divide and conquer, and backtracking). Therefore, it can be used in introductory programming courses, and in more advanced classes on algorithm design. The book also covers lower-level topics related to iteration and program execution, and includes a rich chapter on the theoretical analysis of the computational cost of recursive programs, offering readers the possibility to learn some basic mathematics along the way. It also incorporates several elements aimed at helping students master the material. First, it contains a larger collection of simple problems in order to provide a solid foundation of the core concepts, before diving into more complex material. In addition, one of the book's main assets is the use of a step-by-step methodology, together with specially designed diagrams, for guiding and illustrating the process of developing recursive algorithms. Furthermore, the book covers combinatorial problems and mutual recursion. These topics can broaden students' understanding of recursion by forcing them to apply the learned concepts differently, or in a more sophisticated manner. The code examples have been written in Python 3, but should be straightforward to understand for students with experience in other programming languages. Finally, worked out solutions to over 120 end-of-chapter exercises are available for instructors.

A completely revised edition, offering new design recipes for interactive programs and support for images as plain values, testing, event-driven programming, and even distributed programming. This introduction to programming places computer science at the core of a liberal arts education. Unlike other introductory books, it focuses on the program design process, presenting program design guidelines that show the reader how to analyze a problem statement, how to formulate concise goals, how to make up examples, how to develop an outline of the solution, how to finish the program, and how to test it. Because learning to design programs is about the study of principles and the acquisition of transferable skills, the text does not use an off-the-shelf industrial language but presents a tailor-made teaching language. For the same reason, it offers DrRacket, a programming environment for novices that supports playful, feedback-oriented learning. The environment grows with readers as they master the material in the book until it supports a full-fledged language for the whole spectrum of programming tasks. This second edition has been completely revised. While the book continues to teach a systematic approach to program design, the second edition introduces different design recipes for interactive programs with graphical interfaces and batch programs. It also enriches its design recipes for functions with numerous new hints. Finally, the teaching languages and their IDE now come with support for images as plain values, testing, event-driven programming, and even distributed programming.
