Description

Presents a slideshow walking through an example of Quick Sort. Pseudocode follows along with the prsentation, and an array shows values (letters) and two index pointers. A second version of the presentation is available that focusses on the divide-and-conquer aspects of the algorithm.

Evaluation

Not very compelling, compared to many other alternatives. As the animation progresses, the left and right bounds indexes move under an array, and the pseudocode changes color to show the corresponding step. Not particularly intuitive, no clear sense of the array being broken into subarrays.

HowToUse

For detailed instructions on how to install Animal and run Animal AVs, see: http://www.algoanim.info/Animal2/?q=node/290. Once you have installed the Animal .jar file and downloaded/unpacked the .zip file of Animal animations, you are now ready to run Animal. Run the .jar file to start Animal. Then go to the "Open" menu item, and browse to where you put the animal animations you got in the .zip file. Pick this AV from the list. You can then step through the animation, or use "kiosk mode" to have the steps fed to you at a constant pace.
