［抄题］: 求挖掉一些区域后,能允许出现的最大十字架 In a 2D grid from (0, 0) to (N-1, N-1), every cell contains a 1, except those cells in the given list mines which are 0. What is the largest axis-aligned plus sign of 1s contained in the grid? Return the order of the plus s…

题目如下: In a 2D grid from (0, 0) to (N-1, N-1), every cell contains a 1, except those cells in the given list mines which are 0. What is the largest axis-aligned plus sign of 1s contained in the grid? Return the order of the plus sign. If there is none…

题目大意: 就是一个由1和0组成的正方形矩阵,求里面最大的加号的大小,这个大小就是长度. 什么鬼啊,本来想自己想的,结果看了半天没看懂具体什么意思,然后查了下题解,希望有人说一下意思,结果一上来就是思路,还直接动态规划四个大字,我也是呵呵了 思路一:暴力Brute Force 就是用i, j 循环每一个位置,判断该位置的上下左右的最长“1序列”,复杂度大概是n3 ***这个据说过不了 思路二:动态规划Dynamic Programming 说实话看完源码才想到的,感觉挺好的,直接看源码大把,很好…
