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 $a_i$ friends will join him for skiing, $b_i$ friends will join him for a movie and $c_i$ 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 ( $a_x + b_y + c_z$ ) is maximized.

输入格式

The first line contains a single integer $t$ ( $1 \le t \le 10^4$ ) — the number of testcases.

The first line of each testcase contains a single integer $n$ ( $3 \le n \le 10^5$ ) — the duration of the winter holidays in days.

The second line contains $n$ integers $a_1, a_2, \dots, a_n$ ( $1 \le a_i \le 10^8$ ) — the number of friends that will join Monocarp for skiing on the $i$ -th day.

The third line contains $n$ integers $b_1, b_2, \dots, b_n$ ( $1 \le b_i \le 10^8$ ) — the number of friends that will join Monocarp for a movie on the $i$ -th day.

The fourth line contains $n$ integers $c_1, c_2, \dots, c_n$ ( $1 \le c_i \le 10^8$ ) — 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 $10^5$ .

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.

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, $a_2 = 10$ friends will join him for skiing, $b_1 = 10$ friends will join him for a movie and $c_3 = 10$ 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.
