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.

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).

很好的,装置中阅读器、应答器均具有无线传输功能，频率和调制方式自由选定。不得使用现有射频识别卡或用于识别的专用芯片。装置中的耦合线圈为圆形空芯线圈，用直径不大于1mm的漆包线或有绝缘外皮的导线密绕10圈制成。线圈直径为6.6±0.5 cm（可用直径6.6 cm左右的易拉罐作为骨架，绕好取下，用绝缘胶带固定即可）。线圈间的介质为空气。两个耦合线圈最接近部分的间距定义为D。 阅读器、应答器不得使用其他耦合方式
