LeetCode ProblemMaximum Number of Points From Grid Queries
You are given an m x n integer matrix grid and an array queries of size k. 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: 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. Return the resulting array answer.
