Description:

You are given a number $$$n$$$ and an array $$$b_1, b_2, \ldots, b_{n+2}$$$, obtained according to the following algorithm:

some array $$$a_1, a_2, \ldots, a_n$$$ was guessed;
array $$$a$$$ was written to array $$$b$$$, i.e. $$$b_i = a_i$$$ ($$$1 \le i \le n$$$);
The $$$(n+1)$$$-th element of the array $$$b$$$ is the sum of the numbers in the array $$$a$$$, i.e. $$$b_{n+1} = a_1+a_2+\ldots+a_n$$$;
The $$$(n+2)$$$-th element of the array $$$b$$$ was written some number $$$x$$$ ($$$1 \le x \le 10^9$$$), i.e. $$$b_{n+2} = x$$$; The
array $$$b$$$ was shuffled.

For example, the array $$$b=[2, 3, 7, 12 ,2]$$$ it could be obtained in the following ways:

For the given array $$$b$$$, find any array $$$a$$$ that could have been guessed initially.

The first line contains a single integer $$$t$$$ ($$$1 \le t \le 10^4$$$). Then $$$t$$$ test cases follow.

The first line of each test case contains a single integer $$$n$$$ ($$$1 \le n \le 2 \cdot 10^5$$$).

The second row of each test case contains $$$n+2$$$ integers $$$b_1, b_2, \ldots, b_{n+2}$$$ ($$$1 \le b_i \le 10^9$$$).

It is guaranteed that the sum of $$$n$$$ over all test cases does not exceed $$$2 \cdot 10^5$$$.

For each test case, output:

If there are several arrays of $$$a$$$, you can output any.
