【leetcode】1301. Number of Paths with Max Score 题目如下: You are given a squareboardof characters. You can move on the board starting at the bottom right square marked with the character'S'. You need to reach the top left square marked with the character'E'. The rest of the squares...
the first will be the maximum sum we can collect during the path. and the second is the number of path which there sum is the maximum sum, if overflowed, take module 10^9 + 7. if there is no such path, return the result as [0,0] 也就是说 要找最大加和路径和有多少条这样的路径。
