数据结构和算法面试题：实现一个函数，将一棵二叉树转换为它的镜像。（递归或者非递归实现）

数据结构和算法面试题：实现一个函数，将一棵二叉树转换为它的镜像。（递归或者非递归实现）简介：实现一个函数，将一棵二叉树转换为它的镜像。（递归或者非递归实现）该算法的实现思路如下：对于当前节点，交换其左右子树。递归地对该节点的左右子树进行镜像转换。下面是使用C++实现将一棵二叉树转换为它的镜像（非递归...

算法面试真题详解：输出二叉树

描述按照以下规则在 m*n 二维字符串数组中打印二叉树：行号m应该等于给定二叉树的高度。列号n始终为奇数。根节点的值（以字符串格式）应该放在它可以放入的第一行的正中间。根节点所属的列和行将剩余空间分成两部分（左下部分和右下部分）。您应该在左下部分打印左子树，并在右下部分打印右子树。左下部和右...

算法面试真题详解：二叉树的层次遍历 II

给出一棵二叉树，返回其节点值从底向上的层次序遍历（按从叶节点所在层到根节点所在的层遍历，然后逐层从左往右遍历）在线评测地址：领扣题库官网例1: 输入: {1,2,3} 输出: [[2,3],[1]] 解释: 1 / \ 2 3 它将被序列化为 {1,2,3} 层次遍历例2: 输入: {3,9,2...

[算法总结] 20 道题搞定 BAT 面试——二叉树

本文首发于我的个人博客：尾尾部落 0. 几个概念完全二叉树：若二叉树的高度是h，除第h层之外，其他（1h-1）层的节点数都达到了最大个数，并且第h层的节点都连续的集中在最左边。想到点什么没？实际上，完全二叉树和堆联系比较紧密哈~~ 满二叉树：除最后一层外，每一层上的所有节点都有两个子节点，最后一层...
