4NF OONF News October 2002 November 2002
Last week's Nut's Weekly described an elegant improvement of the Quicksort algorithm. Nice, this splitting into
  • less than or equal
  • and greater than or equal.
But does it really work? This week a java demo of the elegant SUMit Quicksort, with the free java source code.
  1. Enter a string of characters.
  2. See the sorted version.
  3. Study the steps of the sorting algorithm.
Quicksort Demo, Java Applet

This Quicksort demo needs a Java plug-in.
