# Given a schedule of flight departure times and arrival times, write # a program which determines the maximum number of flights in the air at any # one time. # # In this scenario, you run an airport and are responsible for hiring pilots # to manage incoming and outgoing flights. There is a strict requirement that # you must have at least one pilot for each flight concurrently in the air. # # For example, if Flight A takes off at 9AM and lands # at 11AM, Flight B takes off at 10AM and lands at 1PM, and Flight C takes off # a 3PM and lands at 5PM then from the hours of 9AM-10AM one flight will be in # the air, from 10AM-11AM two flights will be in the air, from 11AM-1PM one # flight will be in the air, from 1PM-3PM no flights will be in the air, and # from 3PM-5PM one flight will be in the air. This flight schedule can be # visualized as follows: # # Sample Schedule # --------------- # DEPART ARRIVE # 9:00AM 1:00PM # 10:00AM 11:00AM # 3:00PM 5:00PM # # ________ # | | # | 2 | # -----| |---------- ----------- # | | | | # | 1 | 1 | | 1 | # ------------------------------------------------ # 9:00AM 11:00AM 1:00PM 3:00PM 5:00PM # # # FILE FORMAT # ----------- # " " # " " # " " # " " # " " #
