1. (30 points) The next image is the seating arrangement of a Bombardier CRJ900 of Delta Connection Fleet 1 2 3 4567 8 9 10 11 12 13 14 15 16 17 18 19 20 The seats in rows A and D are called window seats, and the seats in rows B and C are aisle seats. Unlike in the image above, assume that airplane does contain seats Bi-B4 (in First class).

Assume the seats are represented using a two-dimensional list, called seats. Assume the first 4 rows First class," and the rest form the "Delta Comfort" class. Assume that, if a seat is available, it would have the value of None in it. If a seat is taken, i contain the corresponding ticket number (a string value). are ts corresponding cell in the two-dimensional list seats will In what follows: . The parameter seats is the two-dimensional arrays representing the seats on the airplane. . The parameter seatRow is a value between 0 and 19; and The parameter seatCol is one of the values 0 (for 'A), (1, for 'B'), 2 (for 'C"') or 3 (for D) Define the following functions: indicestoSeat: (seatRow, seatcol) : returns the corresponding seat number on the airplane. For example the statement s indicesFromSeat (8, 1) shall set s to "B7" (5 points) isseatAvailable (seats, seatRow, seatcol): returns True if the seat in the given seatRow and seatCol is available. Otherwise, the function returns False. (5 points) findPairAvailable(seats). This function returns a the first two seats that are next two each other (either An-Bn, or Cn-Dn, where n is a row number) that are available in the "Comfort" class. If no seats can be found, the function then returns -1. (15 points) countAisleSeats (seats). Thi "Comfort" class (5 points). is function returns the number of aisle seats available in the
