CF1758B.XOR = Average
XOR = Average
You are given an integer . Find a sequence of integers such that for all and $$a_1 \oplus a_2 \oplus \dots \oplus a_n = \frac{a_1 + a_2 + \dots + a_n}{n},$$where represents the bitwise XOR.
It can be proven that there exists a sequence of integers that satisfies all the conditions above.
Input
The first line of input contains () — the number of test cases.
The first and only line of each test case contains one integer () — the length of the sequence you have to find.
The sum of over all test cases does not exceed .
Output
For each test case, output space-separated integers satisfying the conditions in the statement.
If there are several possible answers, you can output any of them.
Note
In the first test case, .
In the second test case, $13 \oplus 2 \oplus 8 \oplus 1 = \frac{13 + 2 + 8 + 1}{4} = 6$.
