會務(wù)管理系統(tǒng)，運行平臺 Windows Server 2003 Windows 2000 Windows XP Windows 9*/ME Windows NT 簡單得一個網(wǎng)上會務(wù)管理系統(tǒng)，主要是用JAVABEAN組件開發(fā)的，數(shù)據(jù)庫是SQL SERVER 2000，JDBC-ODBC連數(shù)據(jù)庫。
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.
