Luckily, Serval got onto the right bus, and he came to the kindergarten on time. After coming to kindergarten, he found the toy bricks very funny.

翻译中…

He has a special interest to create difficult problems for others to solve. This time, with many $1 \times 1 \times 1$ toy bricks, he builds up a 3-dimensional object. We can describe this object with a $n \times m$ matrix, such that in each cell $(i,j)$, there are $h_{i,j}$ bricks standing on the top of each other.

However, Serval doesn't give you any $h_{i,j}$, and just give you the front view, left view, and the top view of this object, and he is now asking you to restore the object. Note that in the front view, there are $m$ columns, and in the $i$-th of them, the height is the maximum of $h_{1,i},h_{2,i},\dots,h_{n,i}$. It is similar for the left view, where there are $n$ columns. And in the top view, there is an $n \times m$ matrix $t_{i,j}$, where $t_{i,j}$ is $0$ or $1$. If $t_{i,j}$ equals $1$, that means $h_{i,j} \gt 0$, otherwise, $h_{i,j}=0$.

However, Serval is very lonely because others are bored about his unsolvable problems before, and refused to solve this one, although this time he promises there will be at least one object satisfying all the views. As his best friend, can you have a try?

Input

翻译中…

The first line contains three positive space-separated integers $n, m, h$ ($1\leq n, m, h \leq 100$) — the length, width and height.

翻译中…

The second line contains $m$ non-negative space-separated integers $a_1,a_2,\dots,a_m$, where $a_i$ is the height in the $i$-th column from left to right of the front view ($0\leq a_i \leq h$).

翻译中…

The third line contains $n$ non-negative space-separated integers $b_1,b_2,\dots,b_n$ ($0\leq b_j \leq h$), where $b_j$ is the height in the $j$-th column from left to right of the left view.

翻译中…

Each of the following $n$ lines contains $m$ numbers, each is $0$ or $1$, representing the top view, where $j$-th number of $i$-th row is $1$ if $h_{i, j} \gt 0$, and $0$ otherwise.

翻译中…

It is guaranteed that there is at least one structure satisfying the input.

Output

翻译中…

Output $n$ lines, each of them contains $m$ integers, the $j$-th number in the $i$-th line should be equal to the height in the corresponding position of the top view. If there are several objects satisfying the views, output any one of them.
