题目描述

You are given an integer nn . Find a sequence of nn distinct integers a1,a2,,ana_1, a_2, \dots, a_n such that 1ai1091 \leq a_i \leq 10^9 for all ii and $$$$\max(a_1, a_2, \dots, a_n) - \min(a_1, a_2, \dots, a_n)= \sqrt{a_1 + a_2 + \dots + a_n}. $$$$

It can be proven that there exists a sequence of distinct integers that satisfies all the conditions above.

输入格式

The first line of input contains tt ( 1t1041 \leq t \leq 10^4 ) — the number of test cases.

The first and only line of each test case contains one integer nn ( 2n31052 \leq n \leq 3 \cdot 10^5 ) — the length of the sequence you have to find.

The sum of nn over all test cases does not exceed 31053 \cdot 10^5 .

输出格式

For each test case, output nn space-separated distinct integers a1,a2,,ana_1, a_2, \dots, a_n satisfying the conditions in the statement.

If there are several possible answers, you can output any of them. Please remember that your integers must be distinct!

说明/提示

In the first test case, the maximum is 33 , the minimum is 11 , the sum is 44 , and 31=43 - 1 = \sqrt{4} .

In the second test case, the maximum is 2929 , the minimum is 1818 , the sum is 121121 , and 2918=12129-18 = \sqrt{121} .

For each test case, the integers are all distinct.
