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. Found inside – Page 69720.10. Recursion. vs. Iteration. Recursion is an alternative form of program control. It is essentially repetition without a loop. When you use loops, you specify a loop body. The repetition of the loop body is controlled by the loop control structure. Found insideIt can transform the internal dynamics of applications and has the capacity to transform bad code into good code. This book offers an introduction to refactoring. The goal of this concise book is not just to teach you Java, but to help you think like a computer scientist. You’ll learn how to program—a useful skill by itself—but you’ll also discover how to use programming as a means to an end.
