After graduating from the University of Notre Dame, you obtained a job at Top Shelf Software, Inc., as an entry-level computer engineer. On the first day, your manager sits down with you and tasks you with the following job: “We want to see how well you understand computer programming and the abstract science behind it. As an evaluation for all of our new hires, we require them to write a program to determine the relationship between pairs of sets. I’m quite sure that you’ll do well; my confidence is high. Here’s a list of requirements for what the program should do. Good luck.”
Your program should accept an even number of lines of text. Each pair of lines will represent two sets; the first line represents set A, the second line represents set B. Each line of text (set) will be a list of distinct integers.
After each pair of lines has been read in, the sets should be compared and one of the following responses should be output:
An empty line denotes the empty set. Apply equality and proper-subset classifications before disjointness; thus two empty sets are equal, and an empty set is a proper subset of a nonempty set.

A equals B B is a proper subset of A A is a proper subset of B A and B are disjoint I'm confused!
