翻译中…
You are given a positive integer $n$. Please find an array $a_1, a_2, \ldots, a_n$ that is perfect.
翻译中…
A perfect array $a_1, a_2, \ldots, a_n$ satisfies the following criteria:
翻译中…
$1 \le a_i \le 1000$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$n$.

Input
翻译中…
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.
翻译中…
The only line of each test case contains a single positive integer $n$ ($1 \le n \le 200$) — the length of the array $a$.

Output
翻译中…
For each test case, output an array $a_1, a_2, \ldots, a_n$ that is perfect.

In the third test case:
翻译中…
$a_1 = 1$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:
翻译中…
$a_1 = 3$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$5$.
