CF1896E.Permutation Sorting

You are given a permutation $^\dagger$ $a$ of size $n$ . We call an index $i$ good if $a_i=i$ is satisfied. After each second, we rotate all indices that are not good to the right by one position. Formally,

• Let $s_1,s_2,\ldots,s_k$ be the indices of $a$ that are not good in increasing order. That is, $s_j < s_{j+1}$ and if index $i$ is not good, then there exists $j$ such that $s_j=i$ .
• For each $i$ from $1$ to $k$ , we assign $a_{s_{(i \% k+1)}} := a_{s_i}$ all at once.

For each $i$ from $1$ to $n$ , find the first time that index $i$ becomes good.

$^\dagger$ A permutation is an array consisting of $n$ distinct integers from $1$ to $n$ in arbitrary order. For example, $[2,3,1,5,4]$ is a permutation, but $[1,2,2]$ is not a permutation ( $2$ appears twice in the array) and $[1,3,4]$ is also not a permutation ( $n=3$ but there is $4$ in the array).

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 $n$ ( $1 \le n \le 10^6$ ) — the size of permutation $a$ .

The second line of each test case contains $n$ integers $a_1, a_2, \ldots, a_n$ ( $1 \le a_i \le n$ ) — the elements of permutation $a$ .

It is guaranteed that the sum of $n$ over all test cases does not exceed $10^6$ .

For each test case, output a single line containing $n$ integers where the $i$ -th integer represents the first time that index $i$ becomes good.

In the first test case, $2$ and $5$ are already in the correct position so indices $2$ and $5$ become good at $0$ second. After $1$ second, a cyclic shift will be done with $s=[1, 3, 4]$ , resulting in array $a=[1, 2, 3, 4, 5]$ . Notice that indices $1$ , $3$ and $4$ become good at $1$ second.

In the second test case, $5$ is already in the correct position, so index $5$ becomes good at $0$ second. After $1$ second, a cyclic shift will be done with $s=[1, 2, 3, 4, 6]$ , resulting in array $a=[3, 2, 1, 4, 5, 6]$ . Notice that indices $2$ , $4$ and $6$ become good at $1$ second. After $2$ seconds, a cyclic shift will be done with $s=[1, 3]$ , resulting in array $a=[1, 2, 3, 4, 5, 6]$ . Notice that indices $1$ and $3$ become good at $2$ second.
