## Description
2+
3+
There are $n$ brackets, and you want to know whether they are matched.
4+
5+
The brackets will only contain $\{,\},(,),[,]$.
6+
7+
Here is the matching rules.
8+
9+
For example, {{[}]} is not matching, but [{{}}()] is matching.
10+
11+
Please write a program to check whether the given string is matched or not.
12+
13+
## Input
14+
15+
The first line will be an integer $T$, which is the number of test cases. $(1 \leq T \leq 10)$
16+
17+
For each test case, the first line will be an integer $n$ $(1 \leq n \leq 30000)$
18+
19+
Then there is a line with $n$ brackets.
20+
21+
## Output
22+
23+
For each test case, print YES if the test case is a matching case.
24+
25+
Otherwise, print NO.
26+
27+
## Sample Input
28+
29+
``` log

```
46+
47+
## Sample Output
48+
49+
``` log
50+
NO
51+
YES
52+
NO
53+

### 算法分析
60+
61+
本题采用栈结构判断括号序列是否合法. 遍历字符串, 遇到左括号入栈, 遇到右括号判断栈顶是否为对应类型的左括号, 若匹配则弹栈, 否则不合法. 最终栈为空则匹配成功, 否则失败.
62+
63+
该算法时间复杂度为 $O(n)$, 空间复杂度为 $O(n)$.
