Regular Bracket Sequence

1000ms 524288K

Description:

A bracket sequence is called regular if it is possible to obtain correct arithmetic expression by inserting characters + and 1 into this sequence. For example, sequences (())(), () and (()(())) are regular, while )(, (() and (()))( are not. Let's call a regular bracket sequence "RBS".

You are given a sequence $$$s$$$ of $$$n$$$ characters (, ), and/or ?. There is exactly one character ( and exactly one character ) in this sequence.

You have to replace every character ? with either ) or ( (different characters ? can be replaced with different brackets). You cannot reorder the characters, remove them, insert other characters, and each ? must be replaced.

Determine if it is possible to obtain an RBS after these replacements.

Input:

The first line contains one integer $$$t$$$ ($$$1 \le t \le 1000$$$) — the number of test cases.

Each test case consists of one line containing $$$s$$$ ($$$2 \le |s| \le 100$$$) — a sequence of characters (, ), and/or ?. There is exactly one character ( and exactly one character ) in this sequence.

Output:

For each test case, print YES if it is possible to obtain a regular bracket sequence, or NO otherwise}.

You may print each letter in any case (for example, YES, Yes, yes, yEs will all be recognized as positive answer).

Sample Input:

5
()
(?)
(??)
??()
)?(?

Sample Output:

YES
NO
YES
YES
NO

Note:

In the first test case, the sequence is already an RBS.

In the third test case, you can obtain an RBS as follows: ()() or (()).

In the fourth test case, you can obtain an RBS as follows: ()().
