Description

Input

Each test contains multiple test cases. The first line contains the number of test cases $t$ ($1 \le t \le 10^5$). The description of the test cases follows.

The first line of each test case has a single integer $n$ ($1 \leq n \leq 10^5$).

The next line contains $n$ integers $a_1, a_2, \ldots, a_n$ ($1 \leq a_i \leq 10^9$).

It is guaranteed that the sum of $n$ across all test cases does not exceed $2 \cdot 10^5$.

Output

For each test case, output $n$ integers $b_1, b_2, \ldots, b_n$ — a valid rival to $a$ such that $b_1 + b_2 + \cdots + b_n$ is maximal.

If there exist multiple rivals with the maximum sum, output any of them.

Note

For the first test case, one rival with the maximal sum is $[2, 4, 2, 3, 3]$.

$[2, 4, 2, 3, 3]$ can be shown to be a rival to $[1, 4, 1, 3, 3]$.

All possible subarrays of $a$ and $b$ and their corresponding powers are listed below:

• The power of $a[1:1] = [1] = 0$, the power of $b[1:1] = [2] = 0$.
• The power of $a[1:2] = [1, 4] = 4$, the power of $b[1:2] = [2, 4] = 4$.
• The power of $a[1:3] = [1, 4, 1] = 4$, the power of $b[1:3] = [2, 4, 2] = 4$.
• The power of $a[1:4] = [1, 4, 1, 3] = 4$, the power of $b[1:4] = [2, 4, 2, 3] = 4$.
• The power of $a[1:5] = [1, 4, 1, 3, 3] = 4$, the power of $b[1:5] = [2, 4, 2, 3, 3] = 4$.
• The power of $a[2:2] = [4] = 4$, the power of $b[2:2] = [4] = 4$.
• The power of $a[2:3] = [4, 1] = 4$, the power of $b[2:3] = [4, 2] = 4$.
• The power of $a[2:4] = [4, 1, 3] = 4$, the power of $b[2:4] = [4, 2, 3] = 4$.
• The power of $a[2:5] = [4, 1, 3, 3] = 4$, the power of $b[2:5] = [4, 2, 3, 3] = 4$.
• The power of $a[3:3] = [1] = 0$, the power of $b[3:3] = [2] = 0$.
• The power of $a[3:4] = [1, 3] = 0$, the power of $b[3:4] = [2, 3] = 0$.
• The power of $a[3:5] = [1, 3, 3] = 3$, the power of $b[3:5] = [2, 3, 3] = 3$.
• The power of $a[4:4] = [3] = 0$, the power of $b[4:4] = [3] = 0$.
• The power of $a[4:5] = [3, 3] = 3$, the power of $b[4:5] = [3, 3] = 3$.
• The power of $a[5:5] = [3] = 0$, the power of $b[5:5] = [3] = 0$.

It can be shown there exists no rival with a greater sum than $2 + 4 + 2 + 3 + 3 = 14$.
