题目描述
The hero is addicted to glory, and is fighting against a monster.
The hero has $n$ skills. The $i$ -th skill is of type $a_i$ (either fire or frost) and has initial damage $b_i$ .
The hero can perform all of the $n$ skills in any order (with each skill performed exactly once). When performing each skill, the hero can play a magic as follows:
- If the current skill immediately follows another skill of a different type, then its damage is doubled.
In other words, 1. If a skill of type fire and with initial damage $c$ is performed immediately after a skill of type fire, then it will deal $c$ damage;
2. If a skill of type fire and with initial damage $c$ is performed immediately after a skill of type frost, then it will deal $2c$ damage;
3. If a skill of type frost and with initial damage $c$ is performed immediately after a skill of type fire, then it will deal $2c$ damage;
4. If a skill of type frost and with initial damage $c$ is performed immediately after a skill of type frost , then it will deal $c$ damage.
Your task is to find the maximum damage the hero can deal.

输入格式
Each test contains multiple test cases. The first line contains an integer $t$ ( $1 \leq t \leq 10^5$ ) — the number of test cases. The following lines contain the description of each test case.
The first line of each test case contains an integer $n$ ( $1 \leq n \leq 10^5$ ), indicating the number of skills.
The second line of each test case contains $n$ integers $a_1, a_2, \dots, a_n$ ( $0 \leq a_i \leq 1$ ), where $a_i$ indicates the type of the $i$ -th skill. Specifically, the $i$ -th skill is of type fire if $a_i = 0$ , and of type frost if $a_i = 1$ .
The third line of each test case contains $n$ integers $b_1, b_2, \dots, b_n$ ( $1 \leq b_i \leq 10^9$ ), where $b_i$ indicates the initial damage of the $i$ -th skill.
It is guaranteed that the sum of $n$ over all test cases does not exceed $10^5$ .

In the first test case, we can order the skills by $[3, 1, 4, 2]$ , and the total damage is $100 + 2 \times 1 + 2 \times 1000 + 10 = 2112$ .
In the second test case, we can order the skills by $[1, 4, 2, 5, 3, 6]$ , and the total damage is $3 + 2 \times 6 + 2 \times 4 + 2 \times 7 + 2 \times 5 + 2 \times 8 = 63$ .
In the third test case, we can order the skills by $[1, 2, 3]$ , and the total damage is $1000000000 + 1000000000 + 1000000000 = 3000000000$ .
In the fourth test case, there is only one skill with initial damage $1$ , so the total damage is $1$ .
In the second test case, we can order the skills by $[1, 4, 2, 5, 3, 6]$ , and the total damage is $3 + 2 \times 6 + 2 \times 4 + 2 \times 7 + 2 \times 5 + 2 \times 8 = 63$ .
In the third test case, we can order the skills by $[1, 2, 3]$ , and the total damage is $1000000000 + 1000000000 + 1000000000 = 3000000000$ .
In the fourth test case, there is only one skill with initial damage $1$ , so the total damage is $1$ .
