Chapter 7. Sets: No Duplicates

Within the confines of computer science, sets are typically used as a simple collection of objects that contain no duplicates. In the broader realm of mathematics in general, however, a set is an abstract data structure that can be described as a collection of distinct objects or values stored in no particular order. For the purpose of this discussion, we will choose to view a set as the computer implementation of a mathematically finite set.

When working with problems to which the mathematical concepts of set theory can be applied, set data structures provide a powerful group of tools for combining and examining relationships between collections of similar objects. However, even outside set theory and mathematics, ...
