P3509 [CF1651B] Prove Him Wrong
入门
题目描述

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).

Input

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 $a$.

Output

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.

提示

In the first test case, the only possible pairs of indices are $(1, 2)$ and $(2, 1)$.

If you perform the operation on indices $(1, 2)$ (or $(2, 1)$), you'll get $a_1 = a_2 = |1 - 337| = 336$, or array $[336, 336]$. In both cases, the total sum increases, so this array $a$ is a counterexample.
