D. Slimestime limit per test2 secondsmemory limit per test256 megabytesinputstandard inputoutputstandard output

There are $n$ slimes placed in a line. The slimes are numbered from $1$ to $n$ in order from left to right. The size of the $i$-th slime is $a_i$.

Every second, the following happens: exactly one slime eats one of its neighbors and increases its size by the eaten neighbor's size. A slime can eat its neighbor only if it is strictly bigger than this neighbor. If there is no slime which is strictly bigger than one of its neighbors, the process ends.

For example, suppose $n = 5$, $a = [2, 2, 3, 1, 4]$. The process can go as follows:

  • first, the $3$-rd slime eats the $2$-nd slime. The size of the $3$-rd slime becomes $5$, the $2$-nd slime is eaten.
  • then, the $3$-rd slime eats the $1$-st slime (they are neighbors since the $2$-nd slime is already eaten). The size of the $3$-rd slime becomes $7$, the $1$-st slime is eaten.
  • then, the $5$-th slime eats the $4$-th slime. The size of the $5$-th slime becomes $5$, the $4$-th slime is eaten.
  • then, the $3$-rd slime eats the $5$-th slime (they are neighbors since the $4$-th slime is already eaten). The size of the $3$-rd slime becomes $12$, the $5$-th slime is eaten.

For each slime, calculate the minimum number of seconds it takes for this slime to be eaten by another slime (among all possible ways the process can go), or report that it is impossible.

Input

The first line contains a single integer $t$ ($1 \le t \le 10^4$) — the number of test cases.

The first line of each test case contains a single integer $n$ ($1 \le n \le 3 \cdot 10^5$) — the number of slimes.

The second line contains $n$ integers $a_1, a_2, \dots, a_n$ ($1 \le a_i \le 10^9$).

The sum of $n$ over all test cases doesn't exceed $3 \cdot 10^5$.

Output

For each test case, print $n$ integers. The $i$-th integer should be equal to the minimum number of seconds it takes for the $i$-th slime to be eaten by another slime or -1 if it is impossible.

题目大意:
这是一道关于直线排列的史莱姆(Slimes)问题的题目。有n个史莱姆按顺序从1到n排列在一条直线上,第i个史莱姆的大小为a_i。每一秒钟,一个史莱姆会吃掉它旁边的一个比它小的史莱姆,并且增加那个史莱姆的大小。如果一个史莱姆没有比它小的邻居,那么这个过程就结束了。要求计算每个史莱姆被吃掉所需的最少秒数,或者报告它不可能被吃掉。

输入输出数据格式:
输入:
- 第一行包含一个整数t(1≤t≤10^4),表示测试用例的数量。
- 每个测试用例的第一行包含一个整数n(1≤n≤3×10^5),表示史莱姆的数量。
- 每个测试用例的第二行包含n个整数a_1, a_2, …, a_n(1≤a_i≤10^9),表示每个史莱姆的大小。
- 所有测试用例的n之和不超过3×10^5。

输出:
- 对于每个测试用例,输出n个整数。第i个整数表示第i个史莱姆被吃掉所需的最少秒数,或者如果它不可能被吃掉,则输出-1。
