STM32芯片与蓝牙HC-05通讯
蓝牙（Bluetooth）：是一种无线技术标准，可实现固定设备、移动设备和楼宇个人域网之间的短距离数据交换（使用2.4—2.485GHz的ISM波段的UHF无线电波）。蓝牙技术最初由电信巨头爱立信公司于1994年创制，当时是作为RS232数据线的替代方案， 蓝牙可连接多个设备，在与单片机连接使用也得到了广泛应用。
Communication between STM32 Chip and Bluetooth HC-05
Bluetooth: A wireless technology standard that enables short-range data exchange between fixed devices, mobile devices and building personal area networks (using UHF radio waves in ISM bands of 2.4-2.485 GHz). Bluetooth technology was originally created in 1994 by Ericsson, a telecommunications giant, as an alternative to RS232 data line. Bluetooth can connect multiple devices, and it has been widely used in connection with microcontrollers. (2019-06-27, C/C++, 18KB, 下载4次)
ucGUI与emWin是众多嵌入式工程师编写显示界面的首选，但是随着版本的升级，对于商用GUI提出了专利费的要求，这也是国内小型企业所不愿意接受的。于是，编写了一份属于自己的独特GUI界面代码。作品采用stm32作为主MCU，驱动LCM12864进行显示。我们的任务是写自己的GUI，因此对其他外设资源要求不高,包含源代码和原理图。
UcGUI and emWin are the first choice for many embedded engineers to write the display interface, but with the upgrade of the version, the requirement for the patent fee for commercial GUI is put forward, which is also not acceptable to the small enterprises in China. So, I wrote a unique GUI interface code. The work uses STM32 as the main MCU and drives LCM12864 to display. Our task is to write our own GUI, so we have little demand for other peripheral resources.

In addition, because the programming data to be programmed to the target can be saved in the programmer’s non-volatile storage, this programmer is able to work stand-alone without host (PC) intervention. This feature is especially useful in the field without a PC.

组装齿轮问题
譬如，在这个玩具中包含了 6 齿、12 齿和 30 齿的齿轮，而你的弟弟希望搞一个转速比为 5:4 的传动装置。下图就显示了一种可能的方案：
这个传动方案使用了四个齿轮，第一跟轴上是 30 齿和 12 齿的，第二跟轴上是 6 齿和 12 齿的。转速比可以通过如下公式获得：
(30 / 12) * (6 / 12) = (5 / 2) * (1 / 2) = 5 / 4 = 5:4
然而，使用以上三种齿轮，就没法组装出转速比为 1:6 的传动装置。
题目
给定齿轮的大小（齿轮有多少个齿），判断通过这些齿轮能否组成一定的转速比。我们假定每种齿轮的数量都足够多。
输入
输入的第一行是一个数字 n，它表示在玩具中有几种齿轮（1 <= n <= 20）。下一行包含了 n 个数字 c1...cn，以空白符隔开，他们表示了玩具中的 n 种齿轮的大小（5 <= ci <= 100，其中 1 <= i <= n）。你可以假定在玩具中所有齿轮的大小都是最小齿轮大小的倍数。
再下一行有一个整数 m，它表示所需的实现的转速比有多少组，而之后的 m 行中每行都有两个整数 a 和 b，它们表示要实现的转速比为 a:b，其中 1 <= a, b <= 10000。
