🏡Bed & Breakfast Ravelin – quiet and exclusive on the Lower Rhine

**Solution Explanation** The task is simply to output a fixed birthday greeting in six different languages, one line per language. There is no input to read and no computation needed – we just have to print the exact strings shown in the statement. **Algorithm** 1. Prepare a list containing the six required lines (in the exact order). 2. Print each line, followed by a newline. **Correctness Proof** We must show that the program prints exactly the required output. * Let `L` be the list of strings defined in the algorithm: ``` L[0] = "Happy Birthday!" L[1] = "생일 축하합니다!" L[2] = "お誕生日おめでとうございます!" L[3] = "祝你生日快乐!" L[4] = "¡Feliz cumpleaños!" L[5] = "Joyeux anniversaire!" ``` * The algorithm iterates over `L` in order and prints each element followed by a newline. * Therefore, the output consists of the six strings exactly as listed, each on its own line, in the required order. * This matches the specification, so the algorithm is correct. **Complexity Analysis** The algorithm prints six constant‑size strings. Time complexity: `O(1)` Memory usage: `O(1)`. **Reference Implementation (Python 3)** ```python import sys def solve() -> None: # The six greeting lines, exactly as required. greetings = [ "Happy Birthday!", "생일 축하합니다!", "お誕生日おめでとうございます!", "祝你生日快乐!", "¡Feliz cumpleaños!", "Joyeux anniversaire!" ] # Write each line followed by a newline. out = sys.stdout for line in greetings: out.write(line + "\n") if __name__ == "__main__": solve() ``` The program follows the algorithm described above and conforms to the required output format.
