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。 ...
The second implementation provides the same functionality as the first; however, this time we are using the more succinct recursive form. Due to a common Python gotcha withdefault parameter valuesbeing created only once, we are required to create a new visited set on each user invocation. Anothe...
1、DFS(Depth-First-Search)深度优先搜索算法: 是图与树搜索中用到的一种算法: 遍历的思想是:先从根部进行,一直遍历到最底部的叶节点,然后再返回到根节点,判断,如果该根节点上的...,然后全部出栈 当然实际上是通过递归的操作来实现栈上的搜索。 2、BFS(Breadth First Search):广度优先搜索算法 还是借用上图 ...
