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=
An alternative algorithm called breadth-first search provides us with the ability to return the same results as DFS, but with the added guarantee of returning the shortest path first. This algorithm is a little more tricky to implement in a recursive manner; instead, using the queue data struct...

【算法】图的 深度优先搜索 广度优先搜索 复杂度分析 python代码实现 Breadth-First-Search,BFS。 一种“地毯式”层层推进的搜索策略,先查找离起始顶点最近的,然后是次近的,依次往外搜索。 s 表示起始顶点,t 表示终止顶点。搜索一条从 s 到 t...复的,最多遍历全部顶点,所以复杂度是O(n)。 中间的三个辅助...

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
Depth-first search (DFS) is an algorithm for searching in non-linear data structures. There are a few different ways to implement DFS, but here you're going to implement a recursive DFS as part of a Minesweeper game. We'll discuss more about how to do this recursive search later. ...
whenever a Python program encounters the continue statement in a loop, it skips the remainder of the body of the loop and begins the next iteration. One can also combine the last three lines of code into one using the lists’s extend function in combination with a list comprehension. This ...
