Wоrking аt the Cinemа (20) At the lоcаl theater, yоu've been asked to help manage their seating assignment system. Previously, the theater staff would manually assign all of the seats for a particular showing using a large paper roster which often lead to double-booking. Knowing what you know about CSV files, you offered to help write a program that would let the workers reserve a seat using a shared digital file. Each of the files will contain either an X, representing a reserved seat, or an O, representing an open seat. These values are all separated with commas, each line representing a row within a theater. For example, consider the file as shown below: X,O,O,O,X X,X,O,O,O,X,X O,X,X,X,O,O,O O,O,O,O,O,O,O This file represents a theater with four rows of seats. The first row has five seats and the rest have seven. There are nine seats currently reserved: two in the first row, four in the second, three in the third, and none in the fourth.
