C++ program for a system of movie ticket reservations

• Input number of test cases for one of the following types of reservation commands:
• • add-screen: Adds a screen to the cinema system, with the specified number of rows and columns, along with the seat numbers which are the aisle seats in that theatre/screen. prints success if a new screen has been created, and failure if it already exists.
• • reserve-seat: Reserves seats in a particular screen, with given row number and seat numbers. prints failure if not possible and success otherwise.
• • get-unreserved-seats: Prints all the unreserved seat numbers for a particular row at a specified screen.
• • suggest-contiguous seats: Suggests specified number of contiguous unreserved seats in a particular row, taking into account aisle seats, and one preferred seat number which should be necessarily included. prints 'none' if this is not possible in that row
• These commands should be executed in the following fashion:
• • add-screen name-of-screen number-of-rows number-of-columns space-separated-aisle-seats
• • reserve-seat name-of-screen row-number space-separated-seats-to-be-reserved
• • get-unreserved-seats name-of-screen row-number
• • suggest-contiguous-seats name-of-screen number-of-seats row-number choice-of-seat
