题目描述

You are given a permutation a1,a2,,ana_1,a_2,\ldots,a_n of the first nn positive integers. A subarray [l,r][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 kk in the range \[0,n\] , print out the maximum number of copium subarrays of aa over all ways of rearranging the last nkn-k elements of aa$$.

输入格式

Each test contains multiple test cases. The first line contains the number of test cases tt ( 1t1041 \le t \le 10^4 ). The description of the test cases follows.

The first line of each test case contains a single integer nn ( 1n21051\le n\le 2\cdot 10^5 ).

The second line of each test case contains nn integers a1,a2,,ana_1, a_2, \ldots, a_n ( 1ain1 \le a_i \le n ). It is guaranteed that the given numbers form a permutation of length nn .

It is guaranteed that the sum of nn over all test cases does not exceed 21052\cdot 10^5 .

输出格式

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

说明/提示

In the first test case, the answer permutations for each kk are [1,2,3,4,5][1,2,3,4,5] , [5,4,3,2,1][5,4,3,2,1] , [5,2,3,4,1][5,2,3,4,1] , [5,2,1,3,4][5,2,1,3,4] , [5,2,1,4,3][5,2,1,4,3] , [5,2,1,4,3][5,2,1,4,3] .

In the second test case, the answer permutations for each kk are [1,2,3,4][1,2,3,4] , [2,1,3,4][2,1,3,4] , [2,1,3,4][2,1,3,4] , [2,1,4,3][2,1,4,3] , [2,1,4,3][2,1,4,3] .
