Implementation of Sets (I)

This lecture focuses on the implementation of sets, starting with a naive list-based approach and then moving on to a more efficient hash table-based implementation. The instructor explains the design of classes and interfaces, such as the S7 interface for simplified sets and the S abstract 7 class. The lecture covers methods like add, remove, contains, and iterator, emphasizing the differences between sets and lists. The S abstract 7 class is described as similar to S abstract list but tailored for sets. The lecture concludes by introducing the S list 7 class, a simplified version of the hash table-based implementation SH7, setting the stage for further exploration in subsequent videos.
