- What is recursion and when should I use it? - Stack Overflow
There are a number of good explanations of recursion in this thread, this answer is about why you shouldn't use it in most languages * In the majority of major imperative language implementations (i e every major implementation of C, C++, Basic, Python, Ruby,Java, and C#) iteration is vastly preferable to recursion
- What are the advantages and disadvantages of recursion?
With respect to using recursion over non-recursive methods in sorting algorithms or, for that matter, any algorithm what are its pros and cons?
- How to understand the concept of recursion in java?
This is regardless of a method calling itself or another method When the call returns, the stack frame is popped of the stack, the state of the method is restored and execution continues in the calling method Recursion is when a method (directly or indirectly) calls itself The general form of a recursive method is:
- java - What is recursion - Stack Overflow
Recursion is a programming technique where a method can call itself as part of its calculation (sometimes you can have more than one method - the methods would then normally call each other circularly)
- recursion - How can I build a recursive function in python? - Stack . . .
Recursion in Python works just as recursion in an other language, with the recursive construct defined in terms of itself: For example a recursive class could be a binary tree (or any tree):
- algorithm - Understanding recursion - Stack Overflow
Recursion is one of the harder parts of programming to grasp, and while it does require instinct, it can be learned But it does need a good description, good examples, and good illustrations
- recursion - Are recursive functions used in R? - Stack Overflow
Another common algorithm that is expressed naturally in a recursive way is Quicksort This can, like all algorithms be implemented without recursion, but is quite complex to do so There is little benefit in using a non-recursive Quicksort and so it's common to use the naive recursive implementation Recursion is a good implementation choice:
