Control Flow — FizzBuzz Extended

Implement solve(n) that returns a list of strings for numbers from 1 to n (inclusive) following these rules:

• "FizzBuzz" if divisible by both 3 and 5
• "Fizz" if divisible by 3 only
• "Buzz" if divisible by 5 only
• The number as a string otherwise

Raise ValueError("n must be positive") if n < 1.

Examples

• solve(5) → ["1", "2", "Fizz", "4", "Buzz"]
• solve(15)[-1] → "FizzBuzz"
