#part 1: define the variables used in the diagram
#total_slots - type integer -> contains the total slots available in the parking.
#                      Intialy, i am using 20 slots to simplify the tests and the coding. we must change to 375 before the presentation.
#parking_slot - dictionary -> create the dictionary which will have all the parking data.
#
#part2: defining functions. i separated by functions each part of the program to make easer to understand.
#edit.plot- function that edit the dicitonary parking_lot.
#    inputs: slot: integer with the slot number
#             free: boolean with the slot status - true=free false=occupied
#             cat: string with vehicle type
#             platenum: string with plate number
#             entry: string with entry time
#checkfreeslot: search for the next free slot, from the last to the first, return0 if it is full
#     output: integer with the next available slot number
#checkplate: searchthe slot where the given plate number is parked
#       input: platenum - string
#     outputs: slot - integer
#
