This is the easy version of the problem. The only difference is that $$$x=n$$$ in this version. You must solve both versions to be able to hack.

You are given two integers $$$n$$$ and $$$x$$$ ($$$x=n$$$). There are $$$n$$$ balls lined up in a row, numbered from $$$1$$$ to $$$n$$$ from left to right. Initially, there is a value $$$a_i$$$ written on the $$$i$$$-th ball.

For each integer $$$i$$$ from $$$1$$$ to $$$n$$$, we define a function $$$f(i)$$$ as follows:

- Suppose you have a set $$$S = \{1, 2, \ldots, i\}$$$.
- In each operation, you have to select an integer $$$l$$$ ($$$1 \leq l < i$$$) from $$$S$$$ such that $$$l$$$ is not the largest element of $$$S$$$. Suppose $$$r$$$ is the smallest element in $$$S$$$ which is greater than $$$l$$$.   If $$$a_l > a_r$$$, you set $$$a_l = a_l + a_r$$$ and remove $$$r$$$ from $$$S$$$.  If $$$a_l < a_r$$$, you set $$$a_r = a_l + a_r$$$ and remove $$$l$$$ from $$$S$$$.  If $$$a_l = a_r$$$, you choose either the integer $$$l$$$ or $$$r$$$ to remove from $$$S$$$:   If you choose to remove $$$l$$$ from $$$S$$$, you set $$$a_r = a_l + a_r$$$ and remove $$$l$$$ from $$$S$$$.  If you choose to remove $$$r$$$ from $$$S$$$, you set $$$a_l = a_l + a_r$$$ and remove $$$r$$$ from $$$S$$$.
- $$$f(i)$$$ denotes the number of integers $$$j$$$ ($$$1 \le j \le i$$$) such that it is possible to obtain $$$S = \{j\}$$$ after performing the above operations exactly $$$i - 1$$$ times.

For each integer $$$i$$$ from $$$x$$$ to $$$n$$$, you need to find $$$f(i)$$$.

Input format:
The first line contains $$$t$$$ ($$$1 \leq t \leq 10^4$$$) — the number of test cases.

The first line of each test case contains two integers $$$n$$$ and $$$x$$$ ($$$1 \leq n \leq 2 \cdot 10^5; x = n$$$) — the number of balls and the smallest index $$$i$$$ for which you need to find $$$f(i)$$$.

The second line of each test case contains $$$a_1, a_2, \ldots, a_n$$$ ($$$1 \leq a_i \leq 10^9$$$) — the initial number written on each ball.

It is guaranteed that the sum of $$$n$$$ over all test cases does not exceed $$$2 \cdot 10^5$$$.
Output format:
For each test case, output $$$n-x+1$$$ space separated integers on a new line, where the $$$j$$$-th integer should represent $$$f(x+j-1)$$$.

Notes:
In the first test case, you are required to calculate $$$f(5)$$$. It can be shown that after $$$4$$$ operations, $$$S$$$ can contain $$$2$$$, $$$3$$$, or $$$4$$$. The following shows the operations required to make $$$S = \{4\}$$$.

- Initially, $$$S = \{1, 2, 3, 4, 5\}$$$ and $$$a = [1, 2, 3, 2, 1]$$$.
- Choose $$$l = 1$$$. Naturally, $$$r = 2$$$. Since $$$a_1 < a_2$$$, we set $$$a_2 = 1 + 2$$$ and remove $$$1$$$ from $$$S$$$. Now, $$$S = \{2, 3, 4, 5\}$$$ and $$$a = [1, 3, 3, 2, 1]$$$.
- Choose $$$l = 4$$$. Naturally, $$$r = 5$$$. Since $$$a_4 > a_5$$$, we set $$$a_4 = 2 + 1$$$ and remove $$$5$$$ from $$$S$$$. Now, $$$S = \{2, 3, 4\}$$$ and $$$a = [1, 3, 3, 3, 1]$$$.
- Choose $$$l = 3$$$. Naturally, $$$r = 4$$$. Since $$$a_3 = a_4$$$, we have a choice whether to remove $$$3$$$ or $$$4$$$. Since we want to preserve $$$4$$$, let's remove $$$3$$$. So, set $$$a_4 = 3 + 3$$$ and remove $$$3$$$ from $$$S$$$. Now, $$$S = \{2, 4\}$$$ and $$$a = [1, 3, 3, 6, 1]$$$.
- Choose $$$l = 2$$$. Naturally, $$$r = 4$$$. Since $$$a_2 < a_4$$$, we set $$$a_4 = 3 + 6$$$ and remove $$$2$$$ from $$$S$$$. Finally, $$$S = \{4\}$$$ and $$$a = [1, 3, 3, 9, 1]$$$.

In the second test case, you are required to calculate $$$f(7)$$$. It can be shown that after $$$6$$$ operations, $$$S$$$ can contain $$$2$$$, $$$4$$$, $$$6$$$, or $$$7$$$.
