replaced http://programmers.stackexchange.com/ with https://softwareengineering.stackexchange.com/

I would like to point out that according to the faq this site deals with

algorithm and data structure concepts

These are problems that tend to be reduced to some kind of math problem and many times are best expressed with the help of mathematical notation.

I looked at the solution proposed of using images linked from http://www.codecogs.com/latex/eqneditor.php

but for anything non-trivial this really would be a big PITA.

For instance, I wrote this solution for a problem from Skiena's Algorithm Design Manual.
