题目描述
For an arbitrary grid, Robot defines its beauty to be the sum of elements in the grid.
Robot gives you an array $a$ of length $n$ and an array $b$ of length $m$. You construct a $n$ by $m$ grid $M$ such that $M_{i,j}=a_i\cdot b_j$ for all $1 \leq i \leq n$ and $1 \leq j \leq m$.
Then, Robot gives you $q$ queries, each consisting of a single integer $x$. For each query, determine whether or not it is possible to perform the following operation exactly once so that $M$ has a beauty of $x$:
- Choose integers $r$ and $c$ such that $1 \leq r \leq n$ and $1 \leq c \leq m$
- Set $M_{i,j}$ to be $0$ for all ordered pairs $(i,j)$ such that $i=r$, $j=c$, or both.
Note that queries are not persistent, meaning that you do not actually set any elements to $0$ in the process — you are only required to output if it is possible to find $r$ and $c$ such that if the above operation is performed, the beauty of the grid will be $x$. Also, note that you must perform the operation for each query, even if the beauty of the original grid is already $x$.
Input
The first line contains three integers $n$, $m$, and $q$ ($1 \leq n,m \leq 2\cdot 10^5, 1 \leq q \leq 5\cdot 10^4$) — the length of $a$, the length of $b$, and the number of queries respectively.
The second line contains $n$ integers $a_1, a_2, \ldots, a_n$ ($0 \leq |a_i| \leq n$).
The third line contains $m$ integers $b_1, b_2, \ldots, b_m$ ($0 \leq |b_i| \leq m$).
The following $q$ lines each contain a single integer $x$ ($1 \leq |x| \leq 2\cdot 10^5$), the beauty of the grid you wish to achieve by setting all elements in a row and a column to $0$.
Output
For each testcase, output "YES" (without quotes) if there is a way to perform the aforementioned operation such that the beauty is $x$, and "NO" (without quotes) otherwise.
You can output "YES" and "NO" in any case (for example, strings "yES", "yes" and "Yes" will be recognized as a positive response).

提示
In the second example, the grid is
0 -2 5 0 -3
0 4 -10 0 6
0 -6 15 0 -9
0 0 0 0 0
0 0 0 0 0
By performing the operation with $r=4$ and $c=2$, we create the following grid:
0 0 5 0 -3
0 0 -10 0 6
0 0 15 0 -9
0 0 0 0 0
0 0 0 0 0
which has beauty $4$. Thus, we output YES.
In the second query, selecting $r=3$ and $c=5$ creates a grid with beauty $-3$.
In the third query, selecting $r=3$ and $c=3$ creates a grid with beauty $5$.
