About this unit
This unit gives an overview of algorithms: expressing algorithms in flow chart and pseudocode, testing their correctness, and measuring their efficiency. We also explore heuristics-based approaches for problems that can’t be solved in a reasonable amount of time, introduce the existence of undecidable problems, and explain the computational methods of parallel and distributed computing. With more than 90 questions, you can practice what you've learned and study for the AP Computer Science Principles exam.
