Bài ôn tập: Đồng bộ hoá tiến trìnhTrong giai đoạn thử nghiệm, hầm đường bộ qua đèo Hải Vân chỉ cho phép các phương tiện lưu thông qua hầm với số lượng hạn chế và với những điều kiện nghiêm ngặt. Khi một phương tiện đến đầu hầm sẽ gọi hàm EnterTunnel(direction) để kiểm tra điều kiện vào hầm. Khi đã qua hầm sẽ gọi hàm ExitTunnel(direction) để báo hiệu kết thúc và rời hầm. Giả sử...
