{ "data": { "question": { "questionId": "1737", "questionFrontendId": "1614", "categoryTitle": "Algorithms", "boundTopicId": 439873, "title": "Maximum Nesting Depth of the Parentheses", "titleSlug": "maximum-nesting-depth-of-the-parentheses", "content": "

A string is a valid parentheses string (denoted VPS) if it meets one of the following:

\n\n\n\n

We can similarly define the nesting depth depth(S) of any VPS S as follows:

\n\n\n\n

For example, "", "()()", and "()(()())" are VPS's (with nesting depths 0, 1, and 2), and ")(" and "(()" are not VPS's.

\n\n

Given a VPS represented as string s, return the nesting depth of s.

\n\n

 

\n

Example 1:

\n\n
\nInput: s = "(1+(2*3)+((8)/4))+1"\nOutput: 3\nExplanation: Digit 8 is inside of 3 nested parentheses in the string.\n
\n\n

Example 2:

\n\n
\nInput: s = "(1)+((2))+(((3)))"\nOutput: 3\n
\n\n

 

\n

Constraints:

\n\n\n", "translatedTitle": "括号的最大嵌套深度", "translatedContent": "

如果字符串满足以下条件之一，则可以称之为 有效括号字符串（valid parentheses string，可以简写为 VPS）：

\n\n\n\n

类似地，可以定义任何有效括号字符串 S 的 嵌套深度 depth(S)：

\n\n\n\n

例如：\"\"、\"()()\"、\"()(()())\" 都是 有效括号字符串（嵌套深度分别为 0、1、2），而 \")(\" 、\"(()\" 都不是 有效括号字符串 。

\n\n

给你一个 有效括号字符串 s，返回该字符串的 s 嵌套深度 。

\n\n

 

\n\n

示例 1：

\n\n
\n输入：s = \"(1+(2*3)+((8)/4))+1\"\n输出：3\n解释：数字 8 在嵌套的 3 层括号中。\n
\n\n

示例 2：

\n\n
\n输入：s = \"(1)+((2))+(((3)))\"\n输出：3\n
\n\n
