Your contribution cannot be approved because it does not follow the Utopian Rules.

• Design or video editing related tutorials, gameplay, simple on-screen instructions, ubiquitous functions (Save, Open, Print, etc.) or basic programming concepts (variables, operators, loops, etc.) will not be accepted.
• Even if abstract data types are not basic programming concepts as one of the stated above, they are still basic features for programming languages and there are lots of simple documentation about them. Since this kind of tutorials don't really add value to the community, they are not approved.
