## 문제

You are given an integer $K$ such that $1 \le K \le 10^6$. Construct any array $A$ of numbers for which the following properties hold:

• The size of $A$ is between $1$ and $30$;
• All elements are integers between $-10^{16}$ and $10^{16}$;
• Let $N$ be the size of $A$. Then there are exactly $K$ subsets $S$ (possibly empty) of set $\{1, 2, \ldots, N\}$ for which $\sum_{i \in S} A_i = 0$.

It can be shown that, under the constraints above, such array $A$ always exists.

## 입력

The first line contains a single integer $t$ ($1 \le t \le 1000$), the number of test cases.

Each of the next $t$ lines contains a single integer $K$ ($1 \le K \le 10^6$).

## 출력

For each test case, on the first line, output a single integer $N$ ($1 \le N \le 30$), the size of your array.

On the second line, output $N$ integers $A_1, A_2, \ldots, A_N$ ($-10^{16} \le A_i \le 10^{16}$), the elements of the array.

Note that the elements of the array don't have to be distinct.
