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.

此项为LM339测试程序,该四电压比较器LM339简介 LM339集成块内部装有四个独立的电压比较器,该电压比较器的特点是:1)失调电压小,典型值为2mV;2)电源电压范围宽,单电源为2-36V,双电源电压为±1V-±18V;3)对比较信号源的内阻限制较宽;4)共模范围很大,为0~(Ucc-1.5V)Vo;5)差动输入电压范围较大,大到可以等于电源电压;6)输出端电位可灵活方便地选用。 LM339集成块采用C-14型封装,由于LM339使用灵活,应用广泛,所以世界上各大IC生产厂、公司竟相推出自己的四比较器,如IR2339、ANI339、SF339等,它们的参数基本一致,可互换使用

8051单片机内部定时器的重叠使用。在某些情况下,两个定时器在程序中都投入使用,由于定时时间长(如1min以上或更长),使两个定时器定时出现重叠时间,即t0定时还未完成,t1也进入定时。如果在软件上处理不好两个定时器间的关系,程序就不可能正常执行下去。

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).
