Problem Statement
翻译中…
We have a grid with $H$ rows and $W$ columns. At first, all cells were painted white.
翻译中…
Snuke painted $N$ of these cells. The $i$-th ( $1 \leq i \leq N$ ) cell he painted is the cell at the $a_i$-th row and $b_i$-th column.

Compute the following:

- For each integer
$j$($0 \leq j \leq 9$), how many subrectangles of size$3×3$of the grid contains exactly$j$black cells, after Snuke painted$N$cells?
