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=

Depth First Search is a recursive algorithm for searching all the vertices of a graph or tree data structure. In this tutorial, you will learn about the depth-first search with examples in Java, C, Python, and C++.
The implementation below uses the stack data structure to build up and return a set of vertices that are accessible within the subject’s connected component. Using Python’s overloading of the subtraction operator to remove items from a set, we are able to add only the unvisited adjacent ve...
The Python logging module comes with the standard library and provides basic logging features. By setting it up correctly, a log message can bring a lot of useful information about when and where the log is fired as well as the log context such as the ru
