题目描述

Tired of his stubborn cowlick, Farmer John decides to get a haircut. He has
$N$ ($1\le N\le 10^5$) strands of hair arranged in a line, and strand $i$ is
initially $A_i$ micrometers long ($0\le A_i\le N$). Ideally, he wants his hair
to be monotonically increasing in length, so he defines the "badness" of his
hair as the number of inversions: pairs $(i,j)$ such that $i < j$ and $A_i >
A_j$.
For each of $j=0,1,\ldots,N-1$, FJ would like to know the badness of his hair
if all strands with length greater than $j$ are decreased to length exactly
$j$.
(Fun fact: the average human head does indeed have about $10^5$ hairs!)

输入格式

The first line contains $N$.
The second line contains $A_1,A_2,\ldots,A_N.$

输出格式

For each of $j=0,1,\ldots,N-1$, output the badness of FJ's hair on a new line.
Note that the large size of integers involved in this problem may require the
use of 64-bit integer data types (e.g., a "long long" in C/C++).
