Flowcharting recursion based on data flow
Sabah Al‐Fedaghi · 2015
Since the sixties of the previous century, recursion has developed as a programming design option and has become established as an influential instrument for specifying algorithms. The use of visual representations has become a necessary tool for understanding the mechanics of recursion; however, current diagramming methods are not based on a systematic foundation that visualizes the recursion process. This paper presents such a method that describes the recursive process in a precise, visual way that assists in teaching and documentation.
