Seat Reservation prog for the theatre. Write a function for
seat allocation for the movie tickets. Total no of seats
available are 200. 20 in each row. Each row is referred by
the Character, "A" for the first row and 'J' for the last.
And each seat in a row is represented by the no. 1-20. So
seat in diffrent rows would be represented as
A1,A2....;B1,B2.....;........J1,J2... Each cell in the
table represent either 0 or 1. 0 rep would seat is
available , 1 would represent seat is reserved.
Booking should start from the last row (J) to the first
row(A). At the max 20 seats can be booked at a time. if
seats are available, then print all the seat nos like "B2"
i.e (2 row, 3 col) otherwise Print "Seats are not
available." and we must book consecutive seats only.
