A14910 | Prove Him Wrong

Recently, your friend discovered one special operation on an integer array $a$ :

1. Choose two indices $i$ and $j$ ( $i \neq j$ );
2. Set $a_i = a_j = |a_i - a_j|$ .

After playing with this operation for a while, he came to the next conclusion:

- For every array $a$ of $n$ integers, where $1 \le a_i \le 10^9$ , you can find a pair of indices $(i, j)$ such that the total sum of $a$ will decrease after performing the operation.

This statement sounds fishy to you, so you want to find a counterexample for a given integer $n$ . Can you find such counterexample and prove him wrong?

In other words, find an array $a$ consisting of $n$ integers $a_1, a_2, \dots, a_n$ ( $1 \le a_i \le 10^9$ ) such that for all pairs of indices $(i, j)$ performing the operation won't decrease the total sum (it will increase or not change the sum).

The first line contains a single integer $t$ ( $1 \le t \le 100$ ) — the number of test cases. Then $t$ test cases follow.

The first and only line of each test case contains a single integer $n$ ( $2 \le n \le 1000$ ) — the length of array $a$ .

For each test case, if there is no counterexample array $a$ of size $n$ , print NO.

Otherwise, print YES followed by the array $a$ itself ( $1 \le a_i \le 10^9$ ). If there are multiple counterexamples, print any.
