You are given an m x n integer matrix grid and an array queries of size k.

\n\n

Find an array answer of size k such that for each integer queries[i] you start in the top left cell of the matrix and repeat the following process:

\n\n\n\n

After the process, answer[i] is the maximum number of points you can get. Note that for each query you are allowed to visit the same cell multiple times.

\n\n

Return the resulting array answer.

\n\n

 

\n

Example 1:

\n\"\"\n
\nInput: grid = [[1,2,3],[2,5,7],[3,5,1]], queries = [5,6,2]\nOutput: [5,8,1]\nExplanation: The diagrams above show which cells we visit to get points for each query.
\n\n

Example 2:

\n\"\"\n
\nInput: grid = [[5,2,1],[1,1,2]], queries = [3]\nOutput: [0]\nExplanation: We can not get any points because the value of the top left cell is already greater than or equal to 3.\n
\n\n

Constraints:

\n\n\n", "translatedTitle": "矩阵查询可获得的最大分数", "translatedContent": "

给你一个大小为 m x n 的整数矩阵 grid 和一个大小为 k 的数组 queries

\n\n

找出一个大小为 k 的数组 answer ,且满足对于每个整数 queries[i] ,你从矩阵 左上角 单元格开始,重复以下过程:

\n\n\n\n

在过程结束后,answer[i] 是你可以获得的最大分数。注意,对于每个查询,你可以访问同一个单元格 多次

\n\n

返回结果数组 answer

\n\n

 

\n\n

示例 1:

\n\"\"\n
\n输入:grid = [[1,2,3],[2,5,7],[3,5,1]], queries = [5,6,2]\n输出:[5,8,1]\n解释:上图展示了每个查询中访问并获得分数的单元格。
\n\n

示例 2:

\n\"\"\n
\n输入:grid = [[5,2,1],[1,1,2]], queries = [3]\n输出:[0]\n解释:无法获得分数,因为左上角单元格的值大于等于 3 。\n
