WHAT IS IT?

This model determines the smallest legal base for a random digit pattern. The quiz will test your understanding of this concept.

HOW IT WORKS

The arrow passes through the digits from one side to the other, remembering the largest digit it finds. The digit pattern will be legal in all bases that are larger than the largest digit found, so the smallest legal base is one more than that largest digit.

Applets on this website were written by Teresa Carrigan in 2004, for use in computer science courses at Blackburn College, with the exception of the Fireworks applet. The applets made with NetLogo require Java 1.4.1 or higher to run. The applets made with NetBeans require Java 1.4.2 or higher to run. Applets might not run on Windows 95 or Mac OS 8 or 9. You may obtain the latest Java plugin from Sun's Java site.
