from 01204212

You have a string consisting of parentheses ( ), curly braces { }, and brackets [ ]. You want to check if they are properly balanced. The following are examples of balanced strings:

(()())(())((())())
[()[]]
{[]}{[][](()[])}

These are unbalanced strings:

)(
[[))
[{]}
{{{{}}}}}

You want to write a program that performs the balance checking.

Input/Output

Input

• The first line: an integer T, the number of test cases.
• The next T lines: each line contains a string representing each test case.

Output

For each test case, output either yes if the string is balanced, and no if the string is not balanced.

Example

Input

8
()()(())
((((
[[](){{}}]
[][][]()(){}
[[{]}]
[]]
(())[[]]{{}}({[]})
[]][

Output

yes
no
yes
yes
no
no
yes
no

public class Main {

    public static void main(String[] args) throws Exception {
        Main m = new Main();
        m.process();

    private void process() throws Exception {
        BufferedReader reader = new BufferedReader(
                   new InputStreamReader(System.in) );

        int t = Integer.parseInt(reader.readLine());
        
        for(int i=0; i<t; i++) {
            String st = reader.readLine(); 
            
            if(check(st)) {
                System.out.println("yes");
            } else {
                System.out.println("no");                
            }
        }
