Description
The first link is to the Quicksort applet, that is part of a larger tutorial on Quicksort and bubblesort.
Evaluation
Since I can’t read German, I can’t evaluate the quality of the tutorial, nor explain why these two particular algorithms are juxtaposed. However, the Quicksort applet itself, while visually quite appealing, is poor pedagogically. The example is tiny (5 values). The index graphics are hard to comprehend. There is poor sense of the array being broken into subarrays. This is a canned animation, with no user interaction.
Usage Notes
Clicking on the link above will take you to a “table of contents” for the heapsort tutorial. You can click on sections, or you can follow the forward/backward arrows to go through the tutorial.
