Description: 数字翻译问题
设有输入3个数组:
String x[]={ "one",“two", "three",four", "five","six",seven","eight","nine"}
String y[]={ten","eleven","twelve","thirteen","fourteen","fifteen", "sixteen","seventeen","eighteen","nineteen" }
String z[]={"twenty","thirty","fourty","fifty", "sixty","seventy", "eighty","ninety" }
输入一个大于0，小于100的整数，将整数翻成英文。
例如：输入32，输出：thirty two

Description: 同一个数会由于采用不同的基数而使得其表现的形式是完全不一样的，在我们的学习中，我们熟悉的基数有10进制、12进制、60进制、2进制、8进制和16进制。比如数据12，如果我们用2进制表示，则它就是1100；如果用3进制表示就是110；如果用8进制表示则是14。我们的编程任务就是与数的进制（也就是基数）有关。
程序中我们会给大家很多个数对（假设每个数对的数用X和Y表示），程序需要解决的问题就是为X和Y各选择一个最小的基数，以使得这两个数在其选择的基数上是一对相等的数。
例如，12和5这个数对，我们可以为12选择基数3，为5选择基数6，这样一来12（base 3）=5（base 6），因为12（base 3）就是10进制数5，而5（base 6）也是10进制数中的5。
程序的输入是通过文件完成的。
文件中的每一行都包含一个数对X和Y,两个数通过一个或多个空格符分割，与X和Y相关联的有效基数值范围为2~36。X和Y的合理数值表示字符包括0—9和A-Z（表示数值10-35）。
文件的最后一行用一个数字0表示输入的结束。-same number will be different because of the base and make its performance in the form of a completely different, In our study, we are familiar with the base 229 10, 229 12, 229 60, 229 2. 8-band 16-band. For example, 12 data, if we use the two-band said, it is 1100; If three-band said is 110; If eight 229 said it is 14. Our task is programming with a number of 229 (or base). We will process all of the many numbers (on the assumption that each number on the number of X-and Y said), procedures need to address the issue of the X and Y choose a minimum base, This makes two to a few in their chosen base is the equivalent of a few. For example, 12 and 5, the figure right, we will be able to choose 12 base 3 to 6 base 5 choice, This one to 12 (base 3) = 5 (base 6), because 12 (base 3) 229 10

Description: 德州仪器(TI)宣布推出业界首款带硬件定位引擎的片上系统(SoC)解决方案 CC2431，以
满足低功耗 ZigBee/IEEE802.15.4 无线传感器网络应用的需求。这款来自 Chipcon 产品系列
的器件可满足多种应用要求，其中包括资产和设备跟踪、库存控制、病患监护、远程控制、
安全监控网络等应用，此外，TI领先的 ZigBee协议栈 Z-Stack 还提供有关支持。
CC2431 建立在业界首款针对低功耗 RF 应用的 SoC 解决方案 CC2430 的基础之上。上
述两款器件将业界领先的CC2420 RF收发器内核与增强型8051微控制器的出色性能完美结
合，具有高达 128kB 的闪存、8kB的 RAM 以及许多附加功能，而这一切仅采用一个 7 毫米
x7 毫米小型封装就实现了。
CC2431基于RSSI(Received Signal Strength Indicator)的定位引擎能根据接收信号强度与
已知 CC2430参考节点位置准确计算出有关节点位置，然后将位置信息发送给接收端，如电
脑、PDA、手机等。相比于集中型的定位系统，RSSI 功能降低了网络流量与通信延迟，在
典型应用中可实现 3 至5 米的精度。-The CC2431 is a true System-On-Chip (SOC)
for wireless sensor networking ZigBee™ /
802.15.4 solutions with location detection
engine hardware onboard allowing location
accuracy of around 3 meters or less. It
enables ZigBee™ nodes to be built with very
low total bill-of-material costs. The CC2431
combines the excellent performance of the
leading CC2420 RF transceiver with an
industry-standard enhanced 8051 MCU, 128
KB flash memory, 8 KB RAM and many other
powerful features. Combined with the industry
leading ZigBee™ protocol stack (Z-Stack™ )
from Figure 8 Wireless/Chipcon, the CC2431
provides the market’s most competitive
ZigBee™ solution.
The CC2431 is highly suited for systems where
ultra low power consumption is required. This
is achieved by various operating modes. Short
transition times between these modes further
ensure low power consumption.
