题目描述
Winter holidays are coming up. They are going to last for n days.
During the holidays, Monocarp wants to try all of these activities exactly once with his friends:
- go skiing;
- watch a movie in a cinema;
- play board games.
Monocarp knows that, on the i-th day, exactly ai friends will join him for skiing, bi friends will join him for a movie and ci friends will join him for board games.
Monocarp also knows that he can't try more than one activity in a single day.
Thus, he asks you to help him choose three distinct days x,y,z in such a way that the total number of friends to join him for the activities (ax+by+cz) is maximized.
寒假即将到来,假期将持续 n 天。
在此期间,Monocarp 想要和朋友们恰好各体验一次以下三项活动:
- 去滑雪;
- 去电影院看电影;
- 玩桌游。
Monocarp 已知:在第 i 天,恰好有 ai 位朋友陪他去滑雪,bi 位朋友陪他去看电影,ci 位朋友陪他玩桌游。
Monocarp 还知道,他每天最多只能进行一项活动。
因此,他请你帮他选出三个互不相同的日期 x,y,z,使得参与这三项活动的朋友总人数(即 ax+by+cz)最大化。
输入格式
The first line contains a single integer t (1≤t≤104) — the number of testcases.
The first line of each testcase contains a single integer n (3≤n≤105) — the duration of the winter holidays in days.
The second line contains n integers a1,a2,…,an (1≤ai≤108) — the number of friends that will join Monocarp for skiing on the i-th day.
The third line contains n integers b1,b2,…,bn (1≤bi≤108) — the number of friends that will join Monocarp for a movie on the i-th day.
The fourth line contains n integers c1,c2,…,cn (1≤ci≤108) — the number of friends that will join Monocarp for board games on the i-th day.
The sum of n over all testcases doesn't exceed 105.
第一行包含一个整数 t(1≤t≤104)——测试用例的数量。
每个测试用例的第一行包含一个整数 n(3≤n≤105)——寒假的持续天数。
第二行包含 n 个整数 a1,a2,…,an(1≤ai≤108)——第 i 天将与 Monocarp 一起滑雪的朋友人数。
第三行包含 n 个整数 b1,b2,…,bn(1≤bi≤108)——第 i 天将与 Monocarp 一起看电影的朋友人数。
第四行包含 n 个整数 c1,c2,…,cn(1≤ci≤108)——第 i 天将与 Monocarp 一起玩桌游的朋友人数。
所有测试用例的 n 值之和不超过 105。
输出格式
For each testcase, print a single integer — the maximum total number of friends that can join Monocarp for the activities on three distinct days.
对于每个测试用例,输出一个整数——即最多能与 Monocarp 一起参加这三天不同活动的朋友总数。

说明/提示
In the first testcase, Monocarp can choose day 2 for skiing, day 1 for a movie and day 3 for board games. This way, a2=10 friends will join him for skiing, b1=10 friends will join him for a movie and c3=10 friends will join him for board games. The total number of friends is 30.
In the second testcase, Monocarp can choose day 1 for skiing, day 4 for a movie and day 2 for board games. 30+20+25=75 friends in total. Note that Monocarp can't choose day 1 for all activities, because he can't try more than one activity in a single day.
In the third testcase, Monocarp can choose day 2 for skiing, day 3 for a movie and day 7 for board games. 19+19+17=55 friends in total.
In the fourth testcase, Monocarp can choose day 1 for skiing, day 4 for a movie and day 9 for board games. 17+19+20=56 friends in total.
在第一个测试用例中,Monocarp 可以选择第 2 天滑雪、第 1 天看电影、第 3 天玩桌游。这样,将有 a2=10 位朋友和他一起滑雪,b1=10 位朋友和他一起看电影,c3=10 位朋友和他一起玩桌游。朋友总数为 30。
在第二个测试用例中,Monocarp 可以选择第 1 天滑雪、第 4 天看电影、第 2 天玩桌游,总计 30+20+25=75 位朋友。注意:Monocarp 不能在同一天安排多项活动,因此他不能将所有活动都安排在第 1 天。
在第三个测试用例中,Monocarp 可以选择第 2 天滑雪、第 3 天看电影、第 7 天玩桌游,总计 19+19+17=55 位朋友。
在第四个测试用例中,Monocarp 可以选择第 1 天滑雪、第 4 天看电影、第 9 天玩桌游,总计 17+19+20=56 位朋友。
