        A bracket is considered to be any one of the following characters: <strong>(, ), {, }, [, or ]</strong>.
<br><br>
Two brackets are considered to be a matched pair if the an opening bracket (i.e., (, [, or {) occurs to the left of a closing bracket (i.e., ), ], or }) of the exact same type. There are three types of matched pairs of brackets: [], {},and ().
<br><br>
A matching pair of brackets is not balanced if the set of brackets it encloses are not matched. For example, {[(])} is not balanced because the contents in between { and } are not balanced. The pair of square brackets encloses a single, unbalanced opening bracket, (, and the pair of parentheses encloses a single, unbalanced closing square bracket, ].
<br><br>
By this logic, we say a sequence of brackets is balanced if the following conditions are met:
<br><br>
It contains no unmatched brackets.
The subset of brackets enclosed within the confines of a matched pair of brackets is also a matched pair of brackets.<br><br>
Given n strings of brackets, determine whether each sequence of
brackets is balanced. If a string is balanced, return YES. Otherwise, return NO.<br><br>
         <strong>Input:</strong><br><br>
         The first line contains a single integer n, the number of strings.
<br><br>
Each of the next n lines contains a single string s, a sequence of brackets.<br><br>
<strong>Output:</strong><br><br>
For each string, print YES or NO.

1.The string {[()]} meets both criteria for being a balanced string, so we print YES on a new line.
<br><br>
2.The string {[(])} is not balanced because the brackets enclosed by the matched pair { and } are not balanced: [(]).
<br><br>
3.The string {{[[(())]]}} meets both criteria for being a balanced string, so we print YES on a new line.
