Sorting Algorithms

We all know that Quicksort is one of the fastest algorithms for sorting. It's not often, however, that we get a chance to see exactly how fast Quicksort really is. The following applets chart the progress of several common sorting algorthms while sorting an array of data using constant space algorithms. (This is inspired by the algorithm animation work at Brown University and the video Sorting out Sorting from the University of Toronto (circa 1970!).)

Click on each applet to see the algorithm run. Click on the name of the algorithm to see the source.

If you're going to make a copy of this demo, you'll need to also copy the the SortAlgorithm class and the SortItem class.
