Divisible Array
Description
You are given a positive integer $n$. Please find an array $a_1, a_2, \ldots, a_n$ that is perfect.
A perfect array $a_1, a_2, \ldots, a_n$ satisfies the following criteria:
- $1 \le a_i \le 1000$ for all $1 \le i \le n$.
- $a_i$ is divisible by $i$ for all $1 \le i \le n$.
- $a_1 + a_2 + \ldots + a_n$ is divisible by $n$.
Each test contains multiple test cases. The first line contains the number of test cases $t$ ($1 \le t \le 200$). The description of the test cases follows.
The only line of each test case contains a single positive integer $n$ ($1 \le n \le 200$) — the length of the array $a$.
For each test case, output an array $a_1, a_2, \ldots, a_n$ that is perfect.
We can show that an answer always exists. If there are multiple solutions, print any.

Note
In the third test case:
- $a_1 = 1$ is divisible by $1$.
- $a_2 = 2$ is divisible by $2$.
- $a_3 = 3$ is divisible by $3$.
- $a_1 + a_2 + a_3 = 1 + 2 + 3 = 6$ is divisible by $3$.
In the fifth test case:
- $a_1 = 3$ is divisible by $1$.
- $a_2 = 4$ is divisible by $2$.
- $a_3 = 9$ is divisible by $3$.
- $a_4 = 4$ is divisible by $4$.
- $a_5 = 5$ is divisible by $5$.
- $a_1 + a_2 + a_3 + a_4 + a_5 = 3 + 4 + 9 + 4 + 5 = 25$ is divisible by $5$.
