题目描述

A sequence of brackets is called balanced if one can turn it into a valid math expression by adding characters '+' and '1'. For example, sequences '(())()', '()', and '(()(()))' are balanced, while ')(', '(()', and '(()))(' are not.

You are given a binary string ss of length nn . Construct two balanced bracket sequences aa and bb of length nn such that for all 1in1\le i\le n :

  • if si=1s_i=1 , then ai=bia_i=b_i
  • if si=0s_i=0 , then aibia_i\ne b_i

If it is impossible, you should report about it.

输入格式

The first line contains a single integer tt ( 1t1041\le t\le 10^4 ) — the number of test cases.

The first line of each test case contains a single integer nn ( 2n21052\le n\le 2\cdot 10^5 , nn is even).

The next line contains a string ss of length nn , consisting of characters 0 and 1.

The sum of nn across all test cases does not exceed 21052\cdot 10^5 .

输出格式

If such two balanced bracked sequences exist, output "YES" on the first line, otherwise output "NO". You can print each letter in any case (upper or lower).

If the answer is "YES", output the balanced bracket sequences aa and bb satisfying the conditions on the next two lines.

If there are multiple solutions, you may print any.

    NO

说明/提示

In the first test case, a=a= "()()()" and b=b= "((()))". The characters are equal in positions 11 , 33 , 44 , and 66 , which are the exact same positions where si=1s_i=1 .

In the second test case, a=a= "()()((()))" and b=b= "(())()()()". The characters are equal in positions 11 , 44 , 55 , 77 , 88 , 1010 , which are the exact same positions where si=1s_i=1 .

In the third test case, there is no solution.
