Below please find the trial lesson presentation, you should watch it as instructed.

Please note, stopping the lesson in the middle will require you to re-do it. Thus, the lesson must be completed from start to end (including the questions phase). If you happen to stop the lesson in the middle, you can still watch the presentation as much as you like, but the questions at the end can only be answered twice.

We wish you a pleasant learning experience!

FirstQ*
- None of the above fits the requirement
- Both Singleton and Observer, since these patterns complete each other
- Singleton design pattern
- Observer design pattern
Second Q*
- Design patterns might cause performance impact to their generality
- Design patterns cannot be implemented in some programming languages
- The solutions suggested by the design patterns are not tested, hence, likely broken
- Design patterns encourage creativity
Third Q*
- When writing a new program, I will use as many patterns as possible to improve my program’s quality
- When writing a new program, I will use as known patterns to reduce code lines
- When designing a system, I will try to adjust my system to known design patterns
- When designing a system, I will consider using patterns when encountering a specific problem with a known solution
4 Q*
- Yes, only programmers can understand what are design patterns
- Not certain, design patterns are merely theoretical solutions
- Obviously, design patterns are computer programs per se
- Very likely, since programs are segments of code (though not full programs)
