        return n
    return calculate_fibonacci(n-1) + calculate_fibonacci(n-2)

Claude:

# Claude code includes more error handling and comments
def calculate_fibonacci(n: int) -> int:
    """
    Calculate the nth Fibonacci number.
    
    Args:
        n: Position in Fibonacci sequence (0-indexed)
        
    Returns:
        The nth Fibonacci number
        
    Raises:
        ValueError: If n is negative
    """
    if n < 0:
        raise ValueError("n must be non-negative")
    if n <= 1:
        return n
    return calculate_fibonacci(n-1) + calculate_fibonacci(n-2)
