Welcome!

Here you find articles on the subjects of data structures, algorithms and programming concepts. Each and every article is supplemented with code snippets in both C++ and Java, so you can turn to the practice right after reading a tutorial. For the very beginners we developed articles about how to install a development environment and to write simple applications.
