Karen Smith is one of those gifted teens with the power of ESPN. For us normal people, this skill is also known
as telepathy. She can read the minds of people around her, which helps her out because she loves gossip. She
frequently just sits in crowded areas around North Shore High School and uses her ESPN to read the minds of
the people around her. After picking up gossip, she goes to her friends Cady, Regina, and Gretchen to tell
them all these "fetch" stories.
However, the range of her ESPN is limited. Before she starts collecting gossip, she must prepare a certain
amount of ESPN energy E before starting to read people's minds. If she accumulates E energy, she can read
the minds of the people who are at most E units away from her. Distance between two points (x1, y₁) and
(2, 2) is defined as the Manhattan distance
D = |x1 - x2| + |y1 - y2|
Karen goes to the cafeteria to start collecting gossip. She positions herself at the coordinates (K, Ky) and
prepares E energy. Given the positions of the N people in the cafeteria, how many people can Karen collect
gossip from?
Input Format
Input consists of one test case beginning with three space-separated integers N, K₂, and K, which are the
number of people in the cafeteria, and Karen's location respectively.
N lines follow, the ith of which containing two space-separated integers X; and Y₁ denoting the coordinates
of the ith person.
The next line contains a single integer Q. You must answer Q queries.
The next Q lines contain an integer E, which is the energy of Karen for that query.
Constraints
0 ≤N≤ 105
0≤K, K₂, X, Y| ≤ 108
0 ≤E≤ 4.108
1≤Q≤ 105
Output Format
For each query, output one line containing a single integer which denotes the number of people within range
of Karen's ESPN.

The distances of the 3 people are 19, 19, and 2.
With E=30, Karen can use ESPN on all 3 of them.
With E= 6, she can only reach the one 2 units away.
With E = 1, she can't reach any of them with her ESPN.
