Countingsort The discussion of Quicksort in my previous post mentions that the fastest possible sorting algorithms that use comparisons take on the order of N * log(N) steps. Countingsort does not use comparisons so it is not bound by that … Continue reading →

This post begins a series of articles about sorting algorithms. Much of the text originally appeared in the December 1995 issue of Visual Basic Developer magazine, a publication that seems to no longer exist. All of these posts include the … Continue reading →

Implement an interface in C#

Posted on September 14, 2014 by Rod Stephens

Before you can implement an interface, you need to know what an interface is. An interface defines properties, methods, and events that an object must provide to satisfy the interface without providing any implementation of those features. If a class … Continue reading →
