Task: Final Project: (Airplane Seating Assignment) Write a program that can be used to
assign seats for a commercial airplane. The airplane has 13 rows, with six
seats in each row. Rows 1 and 2 are first class, rows 3 through 7 are business
class, and rows 8 through 13 are economy class. program must prompt the user to enter the following information:
a. Ticket type (first class, business class, or economy class)
b. Desired seat
