Question:

What is a set?

Bruce J.
Answer:

A set put simply is a collection of objects. It is often easier to describe them by looking at them i.e. a set of natural numbers: N = {0,1,2,3,...}. Sets are useful to computer scientists as we often have to deal with large data structures which can have large data collections i.e. lists, trees etc.
