题目描述
You are given a permutation $a_1,a_2,\ldots,a_n$ of the first $n$ positive integers. A subarray $[l,r]$ is called copium if we can rearrange it so that it becomes a sequence of consecutive integers, or more formally, if $$$$\max(a_l,a_{l+1},\ldots,a_r)-\min(a_l,a_{l+1},\ldots,a_r)=r-l $$ For each $k$ in the range $\[0,n\]$ , print out the <span class="tex-font-style-bf">maximum</span> number of copium subarrays of $a$ over all ways of rearranging the last $n-k$ elements of $a$$$.
输入格式
Each test contains multiple test cases. The first line contains the number of test cases $t$ ( $1 \le t \le 10^4$ ). The description of the test cases follows.
The first line of each test case contains a single integer $n$ ( $1\le n\le 2\cdot 10^5$ ).
The second line of each test case contains $n$ integers $a_1, a_2, \ldots, a_n$ ( $1 \le a_i \le n$ ). It is guaranteed that the given numbers form a permutation of length $n$ .
It is guaranteed that the sum of $n$ over all test cases does not exceed $2\cdot 10^5$ .

For each test case print $n+1$ integers as the answers for each $k$ in the range $[0,n]$ .
