At this stage in the process the customer’s vehicle is sent to one of the available mechanics on dutyfor a preliminary assessment.assessVehicle: CustomerRegister, CID, SCL -> HHMMDuring this preliminary assessment, the mechanic will take into consideration some key factors thatwill affect the price of the service. The customer would have already indicated what the limit is thatthey are willing to pay (Pay Limit - PL). If the cost of the servicing goes over that limit by more than5%, the mechanic’s assessment cost should make a note on the register but remove the lowest costsfrom the list until it is within that 5% threshold.There is a servicing cost list which denotes the general cost for certain tasks or jobs to be done on avehicle based on the make (MK) of the vehicle. The servicing cost list is of the format🙁"CL", ([Mk, (FH, ET), (TC, ET), (ShT, ET)]))The servicing cost list is a tagged tuple with two elements; the first element is a tag "CL", andthe second element is a tuple of lists of servicing costs per each make of vehicle:• Mk – Make of Vehicle• FH – Full house check cost (float)• TC – Tyre Change cost (float)• ShT – shocks test cost (float)• ET – Estimated time for the service activity.Write a function assessVehicle()that accepts a customer register, customer Id and a servicingcost list as parameters, updates service cost and the estimated time for servicing in the customerrecord that matches the given customer Id, and returns the estimated pickup time HHMM as a stringin 24-hour format• If the vehicle is more than five years old and the make (Mk) is not a Benz, then the mechanicwill have to do a full house check.• A mileage over 100,000 will incur a shocks test if a full house is not being done.• Tyres will need to be changed if the last service date is more than 10 months ago.The estimated pickup time is five (5) minutes before the calculated time between the customer’sarrival time and service time.
