### Prompt

Generate a Cpp solution to the following problem:

A running competition is going to be held soon. The stadium where the competition will be held can be represented by several segments on the coordinate plane:

  * two horizontal segments: one connecting the points (0, 0) and (x, 0), the other connecting the points (0, y) and (x, y); 
  * n + 1 vertical segments, numbered from 0 to n. The i-th segment connects the points (a_i, 0) and (a_i, y); 0 = a_0 < a_1 < a_2 < ... < a_{n - 1} < a_n = x. 



For example, here is a picture of the stadium with x = 10, y = 5, n = 3 and a = [0, 3, 5, 10]:

<image>

A lap is a route that goes along the segments, starts and finishes at the same point, and never intersects itself (the only two points of a lap that coincide are its starting point and ending point). The length of a lap is a total distance travelled around it. For example, the red route in the picture representing the stadium is a lap of length 24.

The competition will be held in q stages. The i-th stage has length l_i, and the organizers want to choose a lap for each stage such that the length of the lap is a divisor of l_i. The organizers don't want to choose short laps for the stages, so for each stage, they want to find the maximum possible length of a suitable lap.

Help the organizers to calculate the maximum possible lengths of the laps for the stages! In other words, for every l_i, find the maximum possible integer L such that l_i mod L = 0, and there exists a lap of length exactly L.

If it is impossible to choose such a lap then print -1.

Input

The first line contains three integers n, x and y (1 ≤ n, x, y ≤ 2 ⋅ 10^5, n ≤ x).

The second line contains n + 1 integers a_0, a_1, ..., a_n (0 = a_0 < a_1 < a_2 < ... < a_{n - 1} < a_n = x).

The third line contains one integer q (1 ≤ q ≤ 2 ⋅ 10^5) — the number of stages.

The fourth line contains q even integers l_1, l_2, ..., l_q (4 ≤ l_i ≤ 10^6) — the lengths of the stages. 

Output

Print q numbers. The i-th number should be equal to the maximum possible length of a suitable lap for the i-th stage, or -1 if it is impossible to choose a lap for that stage.

Example

Input


3 10 5
0 3 5 10
6
24 30 14 16 18 10


Output


24 30 14 16 -1 -1
