Luca has a cypher made up of a sequence of nn wheels, each with a digit aiai written on it. On the ii-th wheel, he made bibi moves. Each move is one of two types:
- up move (denoted by UU): it increases the ii-th digit by 11. After applying the up move on 99, it becomes 00.
- down move (denoted by DD): it decreases the ii-th digit by 11. After applying the down move on 00, it becomes 99.
Example for n=4n=4. The current sequence is 0 0 0 0.
Luca knows the final sequence of wheels and the moves for each wheel. Help him find the original sequence and crack the cypher.
Input
The first line contains a single integer tt (1≤t≤1001≤t≤100) --- the number of test cases.
The first line of each test case contains a single integer nn (1≤n≤1001≤n≤100) --- the number of wheels.
The second line contains nn integers aiai (0≤ai≤90≤ai≤9) --- the digit shown on the ii-th wheel after all moves have been performed.
Then nn lines follow, the ii-th of which contains the integer bibi (1≤bi≤101≤bi≤10) and bibi characters that are either UU or DD --- the number of moves performed on the ii-th wheel, and the moves performed. UU and DD represent an up move and a down move respectively.
Output
For each test case, output nn space-separated digits --- the initial sequence of the cypher.

In the first test case, we can prove that initial sequence was 2,1,12,1,1. In that case, the following moves were performed:
- On the first wheel: 2→D1→D0→D92→D1→D0→D9.
- On the second wheel: 1→U2→D1→U2→U31→U2→D1→U2→U3.
- On the third wheel: 1→D0→U11→D0→U1.
The final sequence was 9,3,19,3,1, which matches the input.

Luca 有一个由 n 个转轮组成的密码，每个转轮上都写有一个数字 ai。在第 i 个转轮上，他进行了 bi
移动。每次移动都有两种类型：
向上移动（用 U 表示）：将第 i 个数字增加 1。在 9 上应用向上移动后，它变为 0。
向下移动（用 D 表示）：将第 i 个数字减少 1。在 0 上应用向下移动后，它变为 9。
n=4 的示例。当前序列为 0 0 0 0。
Luca 知道转轮的最终序列以及每个转轮的移动。帮助他找到原始序列并破解密码。
输入
第一行包含一个整数 t
(1≤t≤100
) --- 测试用例的数量。
每个测试用例的第一行包含一个整数 n
(1≤n≤100
) --- 轮子的数量。

个整数 ai
(0≤ai≤9
) --- 完成所有移动后第 i 个轮子上显示的数字。
接下来是 n

要么是 D
--- 在第 i

注意
在第一个测试用例中，我们可以证明初始序列是 2,1,1
。在这种情况下，执行了以下移动：
在第一个轮子上：2→D1→D0→D9
。
在第二个轮子上：1→U2→D1→U2→U3
。
在第三个轮子上：1→D0→U1
。
最终序列是 9,3,1
，与输入相匹配。
