For DSA there will be easy-medium level

1st round question: The Challenge Rent different kinds of vehicles such as cars and bikes. Features: *Rental service has multiple branches throughout the city. *Each branch has a limited number of different kinds of vehicles. *Each vehicle can be booked with a predefined fixed price. *Each vehicle can be booked in multiples of 1-hour slots each. (For simplicity, assume slots of a single day) Requirements: *Onboard a new branch with available vehicles. *Onboard new vehicle(s) of an existing type to a particular branch. *Rent a vehicle for a time slot and a vehicle type(the lowest price as the default choice extendable to any other strategy). *Display available vehicles for a given branch sorted on price. *The vehicle will have to be dropped at the same branch where it was picked up. Bonus question: *Dynamic pricing – demand vs supply. If 80% of cars in a particular branch are booked, increase the price by 10%. Other Details: *Use the in-memory store. *Do not create any UI for the application. *Write a driver class for demo purposes. Which will execute all the commands in one place in the code and test cases. *Please prioritize code compilation, execution, and completion. *Work on the expected output first and then add good-to-have features of your own. Expectations: *Make sure that you can execute your code and show that it is working. *Make sure that the code is functionally correct. *Work on the expected output first and then add good-to-have features of your own. *Code should be modular and readable. *Separation of concern should be addressed. *Code should easily accommodate new requirements with minimal changes. *Code should be easily testable. *Input can be taken in your desired format[not necessary to follow the same grammar], but the API’s *should remain as is(should contain all the input params) Things to keep in mind while submitting the code: *Coding solution should be in Java. *Working code is required. *Code is evaluated for proper domain modeling and design, need not be optimized. *Separation of concerns must be taken care. *Solution should be extensible. *Writing all the necessary Unit tests is expected. *Necessary design patterns must be implemented. *Naming variable conventions. *Input needs to be read from a text file, and output should be printed to console. Your program should *execute and take the location to the test file as a parameter.
