【LeetCode】【Python】Binary Tree Inorder Traversal
Given a binary tree, return the inorder traversal of its nodes' values. For example: Given binary tree {1,#,2,3}, 比较简单,就是转化成中序遍历即可,访问顺序是中序遍历左子树,根节点,中序遍历右子树 Python编程的时候需要注意,要在返回单一数字的时候加...

leetcode第一刷_Binary Tree Inorder Traversal
递归实现当然太简单,也用不着为了ac走这样的捷径吧。。非递归实现还挺有意思的。树的非递归遍历一定要借助栈,相当于把原来编译器做的事情显式的写出来。对于中序遍历,先要訪问最左下的节点,一定是进入循环后,不断的往左下走,走到不能走为止,这时候,能够从栈中弹出訪问的节点,相当于“左根右”过程的“根”,然后...

C++ implementation of DF Traversal
如下图:     这里我们实现DFS中的三种遍历方法。 相关的如下: 相关算法的介绍不再赘述。 首先对于preorder traversal 的步骤为: 其他两种算法略。 具体递归调用分析, 注意学会画stack frame的图分析。 这里不再赘述。 代码如下: /* Binary Tree Traversal - Preorder, Inorder, Postor...
