What is the use of static constructors?
...ment;
static string urlFragment = "foo/bar";
}
Your fullUrl value is now just "http://www.example.com/" since urlFragment hadn't been initialized at the time fullUrl was being set. Not good. So, you add a static constructor to take care of the initialization:

What is stability in sorting algorithms and why is it important?
...vince yourself of that. (by the way, that algorithm is called radix sort)
Now to answer your question, suppose we have a list of first and last names. We are asked to sort "by last name, then by first". We could first sort (stable or unstable) by the first name, then stable sort by the last name....
