Hi, i have been solving codingbat exercises in java.

I consider myself a beginner and quite often i have to write each iteration with pen/paper to understand what i am doing, especially when using loops and recursion

as a wanna-be-efficient programmer, i suspect it is possible to automate this process,i.e. write some applet or function that you can give parameters and it will go through array/string and highlight every comparison/check step-by-step.

I already tried to google it, but did not find much, only this:http://en.wikipedia.org/wiki/File:Quicksort-example.gif


is there any educational applet/program that you can give parameters like array to go through, operation to do and it will highlight and show slow /fast speed visualization?

Question:
1. do you know software/applet that does it?
2. if not, this could be another idea - write my own project for myself/educational purposes; in this case, how can i do this?

I'm not quite sure what you're asking, but for various visualizations of algorithms, check out section #24 in the https://coderanch.com/how-to/java/JavaBeginnersFaq.
