Problem Statement
We have $N$ polygons on the $xy$-plane.
Every side of these polygons is parallel to the $x$- or $y$-axis, and every interior angle is $90$ or $270$ degrees. All of these polygons are simple.
The $i$-th polygon has $M_i$ corners, the $j$-th of which is $(x_{i, j}, y_{i, j})$.
The sides of this polygon are segments connecting the $j$-th and $(j+1)$-th corners. (Assume that $(M_i+1)$-th corner is the $1$-st corner.)
A polygon is simple when... for any two of its sides that are not adjacent, they do not intersect (cross or touch) each other.
You are given $Q$ queries. For each $i = 1, 2, \dots, Q$, the $i$-th query is as follows.
- Among the
$N$polygons, how many have the point$(X_i + 0.5, Y_i + 0.5)$inside them?
Constraints
$1 \leq N \leq 10^5$$4 \leq M_i \leq 10^5$- Each
$M_i$is even. $\sum_i M_i \leq 4 \times 10^5$$0 \leq x_{i, j}, y_{i, j} \leq 10^5$$(x_{i, j}, y_{i, j}) \neq (x_{i, k}, y_{i, k})$if$j \neq k$.$x_{i, j} = x_{i, j+1}$for$j = 1, 3, \dots M_i-1$.$y_{i, j} = y_{i, j+1}$for$j = 2, 4, \dots M_i$. (Assume$y_{i, M_i +1} = y_{i, 1}$.)- The given polygons are simple.
$1 \leq Q \leq 10^5$$0 \leq X_i, Y_i \lt 10^5$- All values in input are integers.
