1 S S S S S S S S
2 S S S S S S S S
3 S S S S S S S S
4 S S S S S S S S
5 S S S S S S S S
6 S S S S S S S S
7 S S S S S S S S

Stage 2/5: Calculate the profit

In this stage, two positive integer numbers are read from the input: the number of rows, and the number of seats in each row.

The ticket price is determined by the following rules:

• If the total number of seats in the screen room is not more than 60, then the price of each ticket is 10 dollars.
• In a larger room, the tickets are 10 dollars for the front half of the rows and 8 dollars for the back half.
• For odd number of rows, for example 9, the first half is the first 4 rows, and the second half is the other 5 rows.

The calculated profits from the sold tickets and number of seats is printed at the end.

Stage implementation: ProfitsCalculator.java

Example:

Enter the number of rows:
> 8
Enter the number of seats in each row:
> 9
Total income:
$648

Stage 3/5: Set the ticket price

Two positive integer numbers that represent the number of rows and seats in each row are read from the input. Then, the seating arrangement is printed out, like the first stage

Then, two other integer numbers are read from the input: a row number and a seat number in that row. These numbers represent the coordinates of the seat according to which the program should print the ticket price. The ticket price is determined by the same rules as the previous stage:

After that, the program prints out all the seats in the screen room, and mark the chosen seat by the B symbol.
