In some English accents, when you say "two for" quickly, it sounds like "two fer". Two-for-one is a way of saying that if you buy one, you also get one for free. So the phrase "two-fer" often implies a two-for-one offer.
Imagine a bakery that has a holiday offer where you can buy two cookies for the price of one ("two-fer one!"). You take the offer and (very generously) decide to give the extra cookie to someone else in the queue.
Your task is to determine what you will say as you give away the extra cookie.
If you know the person's name (e.g. if they're named Do-yun), then you will say:
One for Do-yun, one for me.
If you don't know the person's name, you will say you instead.
One for you, one for me.
Here are some examples:
| Name | Dialogue |
|---|---|
| Alice | One for Alice, one for me. |
| Bohdan | One for Bohdan, one for me. |
| One for you, one for me. | |
| Zaphod | One for Zaphod, one for me. |
In Cairo, the Option enumeration is used to represent the concept of a value being absent or present.
There are two variants:
Option::None takes no asssociated value and represents no data being present.Option::Some takes an associated value and represents that value being represented like Option::Some(value).
