Quiz 2: Dialogue Graph

Overview

You run a hair salon and recently adopted a dialogue system to take a call from a customer and book a service for the customer:

S: Hello, how can I help you?
U: Hi, I'd like to book a haircut.
S: Sure. What date and time are you looking for?
U: Tuesday at 2 PM.
S: Your appointment is set. See you!

Your salon provides three services: haircut, hair coloring, and perms. Your system should reject any other service request from the customer:

S: Hello, how can I help you?
U: Can I make an appointment for waxing?
S: Sorry, we do not provide that service.
U: OK then.
S: Goodbye.

Your system should understand the following dates: Monday ~ Saturday. The time is always followed by the date with the following format: <number><space><AM|PM>:

S: Hello, how can I help you?
U: Can I make an appointment for a perm?
S: Sure. What date and time are you looking for?
U: Saturday 10 AM.
S: Your appointment is set. See you!

Only the following times and dates are available for the specific services:

• Haircut:

  • Monday 10 AM, 1 PM, 2 PM

  • Tuesday: 2 PM

• Hair coloring:

  • Wednesday: 10 AM, 11 AM, 1 PM

  • Thursday: 10 AM, 11 AM

• Perms

  • Friday: 10 AM, 11 AM, 1 PM, 2 PM

  • Saturday: 10 AM, 2 PM

Thus, your system should not schedule an appointment for any other slots:

S: Hello, how can I help you?
U: Hi, I'd like to book a haircut.
S: Sure. What date and time are you looking for?
U: Saturday 10 AM.
S: Sorry, that slot is not available for a haircut.
U: OK.
S: Goodbye.

Make sure your system does not throw an exception in any situation.
