2 _ _ _ x
3 _ _ _ _
4 _ _ _ _
5 _ _ _ _
6 _ _ _ _
7 _ _ x _

write a program that can display availability of airplane seats (in the format shown above), take customer’s booking of seats and update seat availability after taking customer’s booking. if a customer requests in a seat that is already reserved, your program should say that that seat is occupied and ask for another choice.
