思路1:使用DFS对二叉树进行后序遍历,将每个节点的左右子树的深度求出来,然后判断该节点的左右子树深度是否不超过1,将结果添加到全局变量isBalance中。最后对isBalance进行遍历,如果存在False,则该二叉树不是平衡二叉树,否则是平衡二叉树。 代码: 点击查看代码 class TreeNode: def __init__(self, val=0,left=Non...
迷宫生成算法之一——深度优先算法python代码详解(One of the maze generation algorithm - Depth First Search ——DFS algorithm Python code detail) 最近接触到了生成迷宫的算法,查找了资料了解了迷宫生成的三大经典算法——深度优先、随机Prim、递归分割,本文就深度优先算法的代码进行详细解析,希望能帮助大家理解。 ...
Graph theory and, in particular, the graph ADT (abstract data type) is widely explored and implemented in the field of Computer Science and Mathematics. Consisting of vertices (nodes) and the edges (optionally directed or weighted) that connect them, the data structure is effectively able to re...

图的深度优先搜索(Depth First Search),是图的一种搜索方法,和树的先序遍历比较类似。 它的思想:假设初始状态是图中所有顶点均未被访问,则从某个顶点v出发,首先访问该顶点,然后依次从它的各个未被访问的邻接点出发深度优先搜索遍历图,直至图中所有和v有路径相通的顶点都被访问到。 若此时尚有其他顶点未被访问到...

Depth-first search (DFS) Previous Quiz Next Depth First Search (DFS) algorithm traverses a graph in a depth ward motion and uses a stack to remember to get the next vertex to start a search, when a dead end occurs in any iteration. As in the example given above, DFS algorithm ...
一,图的遍历基本理论 首先定义图的遍历(Traversing Graph):指从图中某一顶点出发访问图中其余顶点,且使每个顶点仅被访问一次。有两种常用的方法可用来搜索图:即深度优先搜索和广度优先搜索。它们最终都会到达所有连通的顶点。深度优先搜索通过栈来实现,而广度优先搜索通过队列来实现。 1,深度优先图搜索 (DFS,Depth-F...
