This lecture provides a recap before the Algorithms exam, covering topics such as problem-solving strategies, algorithm implementation, and theoretical concepts. Students are reminded of exam rules, including the use of handwritten notes, and are presented with sample problems to solve. The problems involve array manipulation, stack and queue operations, binary search trees, flow networks, and cardinality-constrained disjoint intervals. The lecture emphasizes clear explanations and understanding of algorithms to prepare students for the exam.
