A parentheses string is a non-empty string consisting only of '(' and ')'. It is valid if any of the following conditions is true:
().AB (A concatenated with B), where A and B are valid parentheses strings.(A), where A is a valid parentheses string.You are given an m x n matrix of parentheses grid. A valid parentheses string path in the grid is a path satisfying all of the following conditions:
(0, 0).(m - 1, n - 1).Return true if there exists a valid parentheses string path in the grid. Otherwise, return false.
\n
Example 1:
\n\n\nInput: grid = [["(","(","("],[")","(",")"],["(","(",")"],["(","(",")"]]\nOutput: true\nExplanation: The above diagram shows two possible paths that form valid parentheses strings.\nThe first path shown results in the valid parentheses string "()(())".\nThe second path shown results in the valid parentheses string "((()))".\nNote that there may be other valid parentheses string paths.\n\n\nExample 2:
\n![\"\"](\"https://assets.leetcode.com/uploads/2022/03/15/example2drawio.png\")
\n\nInput: grid = [[")",")"],["(","("]]\nOutput: false\nExplanation: The two possible paths form the parentheses strings "))(" and ")((". Since neither of them are valid parentheses strings, we return false.\n\n\n\n
Constraints:
\n\nm == grid.lengthn == grid[i].length1 <= m, n <= 100grid[i][j] is either '(' or ')'.一个括号字符串是一个 非空 且只包含 '(' 和 ')' 的字符串。如果下面 任意 条件为 真 ，那么这个括号字符串就是 合法的 。
() 。AB（A 连接 B），A 和 B 都是合法括号序列。(A) ，其中 A 是合法括号序列。给你一个 m x n 的括号网格图矩阵 grid 。网格图中一个 合法括号路径 是满足以下所有条件的一条路径：
(0, 0) 。(m - 1, n - 1) 。如果网格图中存在一条 合法括号路径 ，请返回 true ，否则返回 false 。
\n\n
示例 1：
\n\n
\n输入：grid = [[\"(\",\"(\",\"(\"],[\")\",\"(\",\")\"],[\"(\",\"(\",\")\"],[\"(\",\"(\",\")\"]]\n输出：true\n解释：上图展示了两条路径，它们都是合法括号字符串路径。\n第一条路径得到的合法字符串是 \"()(())\" 。\n第二条路径得到的合法字符串是 \"((()))\" 。\n注意可能有其他的合法括号字符串路径。\n\n\n
示例 2：
\n\n
\n输入：grid = [[\")\",\")\"],[\"(\",\"(\"]]\n输出：false\n解释：两条可行路径分别得到 \"))(\" 和 \")((\" 。由于它们都不是合法括号字符串，我们返回 false 。\n\n\n
\n\n
提示：
\n\nm == grid.lengthn == grid[i].length1 <= m, n <= 100grid[i][j] 要么是 '(' ，要么是 ')' 。\\u7248\\u672c\\uff1a \\u7f16\\u8bd1\\u65f6\\uff0c\\u5c06\\u4f1a\\u91c7\\u7528
