Llama 3.3 70B × fizzbuzz

```python
def fizzbuzz(n: int) -> list[str]:
    """
    Returns a list of strings for numbers 1 through n, following the FizzBuzz rules:
    - 'Fizz' for multiples of 3
    - 'Buzz' for multiples of 5
    - 'FizzBuzz' for multiples of both
    - The number as a string otherwise

    Args:
        n (int): The upper limit of the FizzBuzz sequence.

    Returns:
        list[str]: A list of strings representing the FizzBuzz sequence.

    Example:
        >>> fizzbuzz(5)
        ['1', '2', 'Fizz', '4', 'Buzz']
    """
    result = []
    for i in range(1, n + 1):
        # Check for multiples of both 3 and 5
        if i % 3 == 0 and i % 5 == 0:
            result.append('FizzBuzz')
        # Check for multiples of 3
        elif i % 3 == 0:
            result.append('Fizz')
        # Check for multiples of 5
        elif i % 5 == 0:
            result.append('Buzz')
        # If none of the above, append the number as a string
        else:
            result.append(str(i))
    return result

# Test the function
if __name__ == "__main__":
    print(fizzbuzz(15))
```

In this code:

*   The `fizzbuzz` function generates a list of strings for numbers 1 through `n`.
*   The function applies the FizzBuzz rules: 'Fizz' for multiples of 3, 'Buzz' for multiples of 5, 'FizzBuzz' for multiples of both, and the number as a string otherwise.
*   The example demonstrates how to call the function and displays the output for `n = 5`.
*   The main block tests the function with `n = 15` and prints the result.
