dfs算法模板: 1.下一层是多节点的dfs遍历 def dfs(array or root, cur_layer, path, result): if cur_layer == len(array) or not root: result.append(path) return for i in range(cur_layer, len(array)): do something with array[cur_layer:i+1] or nodes with this layer path.a
参考网站:https://blog.csdn.net/ldx19980108/article/details/76324307 这个网站里有动态图给我们体现BFS和DFS的区别:https://www.cnblogs.com/0kk470/p/7555033.html 这个算法还算好理解一点吧,有递归的思路,理解了一个上午~ 感觉还不错,看完代码基本上就懂了,可以自己实现了 Fire Net Suppose that we have a square city with straight str
