-/**
- * 921. Minimum Add to Make Parentheses Valid
- *
- * Given a string S of '(' and ')' parentheses, we add the minimum number of parentheses ( '(' or ')', and in any positions )
- * so that the resulting parentheses string is valid.
- *
- * Formally, a parentheses string is valid if and only if:
- * It is the empty string, or
- * It can be written as AB (A concatenated with B), where A and B are valid strings, or
- * It can be written as (A), where A is a valid string.
- * Given a parentheses string, return the minimum number of parentheses we must add to make the resulting string valid.
- *
- * Example 1:
- * Input: "())"
- * Output: 1
- *
- * Example 2:
- * Input: "((("
- * Output: 3
- *
- * Example 3:
- * Input: "()"
- * Output: 0
- *
- * Example 4:
- * Input: "()))(("
- * Output: 4
- *
- * Note:
- * S.length <= 1000
- * S only consists of '(' and ')' characters.
- * */
