2 The challenge
3 ---------------
4
5 You own a pet kennel / boarding / hotel business. Weekends and holidays are very busy. You've had a
6 sudden rush of new customer demand and you need to maximize your profits so you can retire early.
7 Determine the maximum profit possible based on the new demand (customer reservation requests
8 sitting in your Inbox waiting for you to confirm or deny their reservation) given the physical
9 constraints of your hotel.
10
11
12 Your hotel
13 ---------------
14 Cage types:
15
16 SMALL - Single pet
17 Your hotel has 4 small cages.
18
19 LARGE - Single pet >= 60 lbs
20 OR two pets between 20-60 lbs
21 OR three pets < 20 lbs.
22 Your hotel has 3 large cages.
23
24
25 Rules
26 ---------------
27
28 You can stick different customers' pets together in the same LARGE cage. They won't mind.
29
30 BUT you can NEVER stick a dog and a cat in the same cage.
31
32
33 Demand
34 ---------------
35
36 Here are the people you need to email/call back. There is no way you can possibly
37 accomodate everyone, so you'll have to turn away some business. WHICH business you turn away determines
38 how much profit you end up with. You love money, you capitalist swine, so maximize it for the win!
39
40 Reservations must be accepted or rejected entirely. You must board ALL of their pets for ALL of the nights they
41 ask for, or reject them entirely.
42
43 Customers tell you the price they are willing to pay. You can choose to accept or reject their business, you
44 can not set the prices or haggle.
45
46 Here's the demand:
