TransitCalculator.java

//determine best fare option during a visit to NYC. When travelling for different reasons, the period of stay and total number of rides vary. Given that there are several price plans for tickets (i.e. pay-per-ride, 7daysUnlimited, 30daysUnlimited), I made the code to not just find the best plan, but the best combination of plans to maximize savings. You're Welcome!
