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).

這是一個用PL2303轉(zhuǎn)接的JTAG ICE，雖說還是串行通訊，但是我認(rèn)為的確是方便和小巧。驅(qū)動芯片我這裡的74HC245比較多，所以沒用244，其實是一樣的。Mega16L選用的是TQFP封裝。

look1為電子看板的第二個芯片，使用自制的握手信號與look通訊，可以進(jìn)行數(shù)據(jù)傳送，以及控制16個數(shù)碼管顯示，此案例已成功用於生產(chǎn)現(xiàn)志，所用的元件很少，功能較大呢
