Problem: Problem

Given a sequence A with n elements, a sequence B with m elements, q queries each consisting of an integer c.
For each query
The absolute value of the difference between the sum of all [la, ra] in sequence A and the sum of all [lb, rb] in sequence B is c. La, ra, lb, rb (0 ≤ la ≤ ra ≤ ra ≤ Find the number of combinations of n−1, 0 ≤ lb ≤ rb ≤ m−1, sequence numbers start from 0).

Constraints

* 1 ≤ n, m ≤ 4 × 104
* 1 ≤ q ≤ 105
* 1 ≤ ai, bi ≤ 5
* 0 ≤ ci ≤ 2 × 105

Input


n m q
a0 a1 ... an−1
b0 b1 ... bm−1
c0

cq−1


All inputs are given as integers.
The number of elements n and m in the sequence and the number of queries q are given in the first row.
The elements of sequence A are given in the second row, and the elements of sequence B are given in the third row, separated by blanks.
The value ci of each query is given from the 4th line to the q line.
