Collections of Cars Solutions
Given an arbitrary number of collections of cars, find the set of cars that is common to all collections (based on make and model):
Also:
- Identify cars that do not exist in any other collection
- Solve for two collections first, then if possible generalize your solution to handle any number of collections
Optional: For each collection of cars eliminate all but the most expensive instance of each make and model (add another attribute for price)
