We have a group of N items (represented by integers from 1 to N), and we know that there is some total order defined for these items. You may assume that no two elements will be equal (for all a, b: a<b or b<a). However, it is expensive to compare two items. Your task is to make a number of comparisons, and then output the sorted order. The cost of determining if a < b is given by the bth integer of element a of costs (space delimited), which is the same as the ath integer of element b. Naturally, you will be judged on the total cost of the comparisons you make before outputting the sorted order. If your order is incorrect, you will receive a 0. Otherwise, your score will be opt/cost, where opt is the best cost anyone has achieved and cost is the total cost of the comparisons you make (so your score for a test case will be between 0 and 1). Your score for the problem will simply be the sum of your scores for the individual test cases.

Keil c编写的DS1302源代码。DS1302 是美国DALLAS公司推出的一种高性能、低功耗、带RAM的实时时钟电路,它可以对年、月、日、周日、时、分、秒进行计时,具有闰年补偿功能,工作电压为2.5V~5.5V。采用三线接口与CPU进行同步通信,并可采用突发方式一次传送多个字节的时钟信号或RAM数据。DS1302内部有一个31×8的用于临时性存放数据的RAM寄存器。DS1302是DS1202的升级产品,与DS1202兼容,但增加了主电源/后背电源双电源引脚,同时提供了对后背电源进行涓细电流充电的能力。

The XML Toolbox converts MATLAB data types (such as double, char, struct, complex, sparse, logical) of any level of nesting to XML format and vice versa. For example, >> project.name = MyProject >> project.id = 1234 >> project.param.a = 3.1415 >> project.param.b = 42 becomes with str=xml_format(project, off ) "<project> <name>MyProject</name> <id>1234</id> <param> <a>3.1415</a> <b>42</b> </param> </project>" On the other hand, if an XML string XStr is given, this can be converted easily to a MATLAB data type or structure V with the command V=xml_parse(XStr).
