Select a desired algorithm from the Algorithm menu.
Start by setting up a list.
Once the list is generated, choose any of the other algorithms.
Use the speed control to slow down the animation if desired.
Alternatively, use the pause button.
When execution pauses inside of an algorithm, press the "step" button to single-step through
the code or use the "play" button to resume continual execution.
