Rules:

1. This is a grouped assignment. Only the team leader has to submit the solution.
2. The attached source code should be modified and submitted.
3. Your submission WILL BE REJECTED if you used any other language or created a separate project. You must make changes to this current source code.
4. Once the code is complete, run your test cases before submitting the code.

Objective:

1. The program should input two strings: start and destination
2. The output of the program should be a Path containing a list of BusRoute objects specifying Origin as where to take bus from and Terminus as where to drop off.
3. The output should also mention the length of the path in terms of number of stops which occurred during travel.
4. Secondary objective is to provide an optimal solution, i.e. the shortest path which has minimum length, or number of stops in between.

Code:
