Appointment Booking

---

Develop an optimised approach to get the availability of the doctors from their working schedule. Logic can accommodate N number of doctors and existing bookings in the system.

---

• Pseudocode

  • Assumption : parameterised function will be called with list of doctors working schedule, available appointments and number of days. It will return the availability list for given number of days.
  • create day wise list of doctors from their working schedule availability
  • create day wise list of available appointments
  • Loop for each day from current time and check for availability from above two lists.
  • Conditionally produce a list of availability for each doctor (a separate function can be called recursively) and return this list as expected result.

---

• Execution Overview

  • Java main method is called from BookingApplication Class
    • To create dummy data for doctors and appointments, two function called generateDoctorsData() & generateAppointmentsData() .

      List<DoctorScheduleDto> doctorSchedules = generateDoctorsData();
      List<AppointmentsDto> appointments = generateAppointmentsData(); 
      

      • created Dr. Alex works for five days a week and Dr. Peter works on Monday only with standard working schedule from 9am to 6pm.
        • Booked 6 appointments for two users for following date time for both doctors

          • Function will be called with dummy data and expected number of days availability of each doctor we are looking for, expecting for 10 days.

              List<AvailabilityDto> availabilities = getAvailability(appointments, 
                                                                      doctorSchedules,
