Recursion is very intuitive in many cases e.g. trees, graphs and other recursive data structures, for example path finding algorithms rely on recursion. The problem of stackoverflow error can also be solved by tail call optimization and Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-8712770457197348465.post-29872637450996220592014-02-23T20:45:40.744-08:002014-02-23T20:45:40.744-08:00Recursion is not good for production code, it take...Recursion is not good for production code, it takes more memory and space and be careful of creating arrays in recursive code. The amount of space used can pile up very quickly, as can the amount of time required for memory management.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-8712770457197348465.post-77792603822245585182013-02-14T01:11:07.962-08:002013-02-14T01:11:07.962-08:00In order to understand Recursion better or use Rec...In order to understand Recursion better or use Recursion in your code, you should know how to combine result from individual method calls to generate complete result. E.g. In this recursive Fibonacci method you are adding return value of methods. Some time you may need to multiply it e.g. in case of calculating factorial using recursion, you do n*factorial(n-1)Rajninoreply@blogger.comtag:blogger.com,1999:blog-8712770457197348465.post-87290885869483748712013-02-04T17:05:44.996-08:002013-02-04T17:05:44.996-08:00Unless you memoize the results of your Fibonacci c...Unless you memoize the results of your Fibonacci computations, you will be sadly disappointed by the time your application takes. Let's instrument the calls to fibonacci:<br /><br />1. Add a timesCalled variable to the class:<br /><br />private static int timesCalled = 0;<br /><br />2. Insert an increment at the beginning of the fibonacci method:<br /><br />timesCalled++;<br /><br />3.
