Problem Description

Ignatius has just come back school from the 30th ACM/ICPC. Now he has a lot of homework to do. Every teacher gives him a deadline of handing in the homework. If Ignatius hands in the homework after the deadline, the teacher will reduce his score of the final test. And now we assume that doing everyone homework always takes one day. So Ignatius wants you to help him to arrange the order of doing homework to minimize the reduced score.

 

Input

The input contains several test cases. The first line of the input is a single integer T that is the number of test cases. T test cases follow.
Each test case start with a positive integer N(1<=N<=1000) which indicate the number of homework.. Then 2 lines follow. The first line contains N integers that indicate the deadlines of the subjects, and the next line contains N integers that indicate the reduced scores.

 

Output

For each test case, you should output the smallest total reduced score, one line per test case.

问题关键词还是锁定在了学分的身上，我们输出的是最小扣除学分，那么我们就要在有限的时间里边完成最多的高分作业，这个时候我们首先想到了排序.
   
   
     
     
     
     
学分从高到底排序，但这是不够的，还需要把截止时间从小到大排并给每一份作业都预定上做那份作业的时间，预定天数的同时要保证这份作业一定是要价值最高，我们这里就应用了排序的操作，然后就是预定天数的顺序，我们要尽量把作业放在截止的当天去做，能把大量的时间让给重复的作业和之前截止的作业。
