Kevin has recently learned the definition of variance. For an array $$$a$$$ of length $$$n$$$, the variance of $$$a$$$ is defined as follows:

- Let $$$x=\dfrac{1}{n}\displaystyle\sum_{i=1}^n a_i$$$, i.e., $$$x$$$ is the mean of the array $$$a$$$;
- Then, the variance of $$$a$$$ is $$$$$$ V(a)=\frac{1}{n}\sum_{i=1}^n(a_i-x)^2. $$$$$$

Now, Kevin gives you an array $$$a$$$ consisting of $$$n$$$ integers, as well as an integer $$$k$$$. You can perform the following operation on $$$a$$$:

- Select an interval $$$[l,r]$$$ ($$$1\le l\le r\le n$$$), then for each $$$l\le i\le r$$$, increase $$$a_i$$$ by $$$k$$$.

For each $$$1\le p\le m$$$, you have to find the minimum possible variance of $$$a$$$ after exactly $$$p$$$ operations are performed, independently for each $$$p$$$.

For simplicity, you only need to output the answers multiplied by $$$n^2$$$. It can be proven that the results are always integers.

Input format:
Each test contains multiple test cases. The first line of the input contains a single integer $$$t$$$ ($$$1\le t\le 100$$$) — the number of test cases. The description of test cases follows.

The first line of each test case contains three integers $$$n$$$, $$$m$$$, and $$$k$$$ ($$$1\le n,m\le 5000$$$, $$$\color{red}{n\cdot m\le 2\cdot 10^4}$$$, $$$1\le k\le 10^5$$$) — the length of the array $$$a$$$, the maximum number of operations, and the number you add to $$$a_i$$$ each time, respectively.

The second line contains $$$n$$$ integers $$$a_1,a_2,\ldots, a_n$$$ ($$$1\le a_i\le 10^5$$$) — the elements of the array $$$a$$$.

It is guaranteed that the sum of $$$n\cdot m$$$ over all tests does not exceed $$$2\cdot 10^4$$$.
Output format:
For each test case, output $$$m$$$ integers in a single line, the $$$p$$$-th integer denoting the minimum possible variance of $$$a$$$ when exactly $$$p$$$ operations are performed, multiplied by $$$n^2$$$.

Notes:
In the first test case:

- For $$$p = 1$$$, you can perform the operation on $$$[1, 1]$$$, changing $$$a$$$ from $$$[1, 2, 2]$$$ to $$$[2, 2, 2]$$$. Since all of the elements are equal, the variance is equal to $$$0$$$.
- For $$$p = 2$$$, you can perform the operation on $$$[1, 3]$$$ and then $$$[1, 1]$$$, changing $$$a$$$ from $$$[1, 2, 2]$$$ to $$$[2, 3, 3]$$$ to $$$[3, 3, 3]$$$. Since all of the elements are equal, the variance is equal to $$$0$$$.

In the second test case, some possible optimal choices are:

- $$$p=1$$$: $$$[\underline{1,}\,2,2]\to [3,2,2]$$$;
- $$$p=2$$$: $$$[1,\underline{2,2}] \to [\underline{1,}\,4,4] \to [3,4,4]$$$.

In the third test case, some possible optimal choices are:

- $$$p=1$$$: $$$[10,\underline{1,1,1,1,10,1,1,1,1}]\to[10,2,2,2,2,11,2,2,2,2]$$$;
- $$$p=2$$$: $$$[10,1,1,1,1,10,\underline{1,1,1,1}] \to [10,\underline{1,1,1,1},10,2,2,2,2] \to [10,2,2,2,2,10,2,2,2,2]$$$.

In the eighth test case, the optimal choice for all $$$p$$$ is to perform the operation on the whole array $$$p$$$ times.
