使用flood fill遍历网格,当遇到陆地时,我们触发递归使其返回当前陆地以及四周区域陆地(如果有)的面积 代码 这里的递归函数也需要返回值,逻辑如下: 如果调用递归函数后发现当前方格是陆地,那么记录当前面积至累加值,然后递归遍历其四周 如果不是陆地,则结束递归 class Solution { public: int dx[4] = {-1,0,1,0...

To perform a flood fill, consider the starting pixel, plus any pixels connected 4-directionally to the starting pixel of the same color as the starting pixel, plus any pixels connected 4-directionally to those pixels (also with the same color), and so on. Replace the color of all of the...
