题目描述

Kiyora has $n$ whiteboards numbered from $1$ to $n$ . Initially, the $i$ -th whiteboard has the integer $a_i$ written on it.

Koxia performs $m$ operations. The $j$ -th operation is to choose one of the whiteboards and change the integer written on it to $b_j$ .

Find the maximum possible sum of integers written on the whiteboards after performing all $m$ operations.

输入格式

Each test consists of multiple test cases. The first line contains a single integer $t$ ( $1 \leq t \leq 1000$ ) — the number of test cases. The description of test cases follows.

The first line of each test case contains two integers $n$ and $m$ ( $1 \le n,m \le 100$ ).

The second line of each test case contains $n$ integers $a_1, a_2, \ldots, a_n$ ( $1 \le a_i \le 10^9$ ).

The third line of each test case contains $m$ integers $b_1, b_2, \ldots, b_m$ ( $1 \le b_i \le 10^9$ ).

输出格式

For each test case, output a single integer — the maximum possible sum of integers written on whiteboards after performing all $m$ operations.
