To fix the issue, we need to rewrite the regular expression to eliminate the ambiguity that causes exponential backtracking. Specifically, we can replace the ambiguous [^)(]+ with a more precise sub-expression that avoids overlapping matches. Additionally, we can use a more structured approach to match nested parentheses, such as leveraging a library like xregexp for recursive patterns if necessary.
In this case, we will rewrite the regex to use a non-ambiguous pattern for matching nested parentheses. The updated regex will ensure linear time complexity while preserving the original functionality.
