Minimum Path Sum - LeetCode 注意点 数字很大,结果可能会溢出 解法 解法一:dp,走到某一格的位置dp值等于它左边和上面格子中较小的dp值加上该位置的值。其实只需要一个一维数组也可以实现。时间复杂度O(mn) class Solution { public: int minPathSum(vector<vector<int>>& grid) { if(grid.size() ==...
DP: 我们每个点(x,y)都可以表示为dp[x][y] = max( grid[x][y] + dp[x-1][y],grid[x][y] + dp[x][y-1] ) 第一行和第一列需要特殊处理(因为第一行上面没有数,第一列左边没有数) classSolution {publicintminPathSum(int[][] grid) {intdp[][] =newint[grid.length][grid[0].len...
