Problem Statement
Given is a sequence $A = [a_0, a_1, a_2, \dots, a_{N-1}]$ that is a permutation of $0, 1, 2, \dots, N - 1$.
For each $k = 0, 1, 2, \dots, N - 1$, find the inversion number of the sequence $B = [b_0, b_1, b_2, \dots, b_{N-1}]$ defined as $b_i = a_{i+k \bmod N}$.
What is inversion number?
The inversion number of a sequence $A = [a_0, a_1, a_2, \dots, a_{N-1}]$ is the number of pairs of indices $(i, j)$ such that $i < j$ and $a_i > a_j$.Constraints
- All values in input are integers.
- $2 ≤ N ≤ 3 \times 10^5$
- $a_0, a_1, a_2, \dots, a_{N-1}$ is a permutation of $0, 1, 2, \dots, N - 1$.
Input
Input is given from Standard Input in the following format:
$N$ $a_0$ $a_1$ $a_2$ $\cdots$ $a_{N-1}$
Output
Print $N$ lines.
The $(i + 1)$-th line should contain the answer for the case $k = i$.
Sample Input 1
4 0 1 2 3
Sample Output 1
0 3 4 3
We have $A = [0, 1, 2, 3]$.
For $k = 0$, the inversion number of $B = [0, 1, 2, 3]$ is $0$.
For $k = 1$, the inversion number of $B = [1, 2, 3, 0]$ is $3$.
For $k = 2$, the inversion number of $B = [2, 3, 0, 1]$ is $4$.
For $k = 3$, the inversion number of $B = [3, 0, 1, 2]$ is $3$.
