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.
