You're an employee at a local cafe.

You can serve 3 coffee recipes:

• Black = Black Coffee
• Cubano = Cubano coffee + Brown sugar
• Americano = Americano coffee + Milk with 0.5% fat

... and you can add a lot of extra sugar and milk in any coffee, for example:

• Black coffee + Milk with 3.2% fat + Brown sugar
• Cubano coffee + Brown sugar + Brown sugar + Cane sugar
• Americano coffee + Milk with 3.2% fat + Cane sugar

With the following code provided for you, can you create a Coffee by implementing a CoffeeBuilder struct/class?

You can start from scratch or use the following code as a starting off point:

C++
struct Milk {
  float fat;
};

struct Sugar {
  std::string sort;
};

struct Coffee {
  std::string sort;
  std::vector<Milk> milk;
  std::vector<Sugar> sugar;
};

Rust
#[derive(Debug)]
struct Coffee {
    sort: String,
    milk: Vec<Milk>,
    sugar: Vec<Sugar>,
}

#[derive(Debug)]
struct Milk {
    fat: f32,
}

#[derive(Debug)]
struct Sugar {
    sort: String,
}

struct CoffeeBuilder {
    sort: String,
    milk: Vec<Milk>,
    sugar: Vec<Sugar>,
}

Tests

1. A Black coffee with sugar and milk with 3.2% fat, please.
2. A Cubano coffee, please.
3. An Americano with two brown sugars, please.

Good luck!
