This is the hard version of the problem. The only difference is that $$$x=1$$$ in this version. You must solve both versions to be able to hack.

You are given two integers $$$n$$$ and $$$x$$$ ($$$x=1$$$). 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 $$$l$$$ ($$$1 \leq l \lt i$$$) 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 $$$a_l \gt a_r$$$, you set $$$a_l = a_l + a_r$$$ and remove $$$r$$$ from $$$S$$$.
- If $$$a_l \lt a_r$$$, 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

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 $$$x$$$ ($$$1 \leq n \leq 2 \cdot 10^5; x = 1$$$) — 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

For each test case, output $$$n-x+1$$$ space separated integers on a new line, where the $$$j$$$-th integer should represent $$$f(x+j-1)$$$.

Note

In the first test case, below are the possible values of $$$j$$$ for each $$$f(i)$$$ from $$$1$$$ to $$$n$$$.

For $$$f(1)$$$, the only possible value of $$$j$$$ is $$$1$$$.
For $$$f(2)$$$, the only possible value of $$$j$$$ is $$$2$$$.
For $$$f(3)$$$, the possible values of $$$j$$$ are $$$2$$$ and $$$3$$$.
For $$$f(4)$$$, the possible values of $$$j$$$ are $$$2$$$ and $$$3$$$.
For $$$f(5)$$$, the possible values of $$$j$$$ are $$$2$$$, $$$3$$$, and $$$4$$$.
