 # Grid Illumination

You are given an integer A.
On a A x A grid of cells, each cell (x, y) with 0 <= x < A and 0 <= y < A has a lamp.

Initially, some number of lamps are on. B[i] tells us the location of the i-th lamp that is on. Each lamp that
is on illuminates every square on its x-axis, y-axis, and both diagonals (similar to a Queen in chess).

For the i-th query C[i] = (x, y), the answer to the query is 1 if the cell (x, y) is illuminated, else 0.

After each query (x, y) [in the order given by queries], we turn off any lamps that are at cell (x, y) or
are adjacent 8-directionally (ie., share a corner or edge with cell (x, y).)

Return an array of D. Each value D[i] should be equal to the answer of the i-th query C[i].

Input Format

``````The first argument given is the integer A.
The second argument given is the integer matrix B.
The third argument given is the integer matrix C.
``````

Output Format

``````Return an array of integers D. Each value D[i] should be equal to the answer of the i-th query C[i]
``````

Constraints

``````1 <= A <= 10^9
1 <= B.length , C.length <= 20000
B[i].length = C[i].length = 2
``````

For Example

``````Input 1:
A = 5
B = [[0,4], [4,4]]
C = [[1,1], [1,0]]
Output 1:
D = [1, 0]

Input 2:
A = 6
B = [[1,3], [2,4], [5,4]]
C = [[2,4], [1,2]]
Output 2:
D = [1, 0]
