Binary Search Tree Iterator
Implement an iterator over a binary search tree (BST). Your iterator will be initialized with the root node of a BST. Calling next() will return the next smallest number in the BST. Note: next()...

Leetcode 230 Kth Smallest Element in a BST
1. 问题描述  给定一个二叉搜索树,找出第k小的元素。注意:可以假设k总是存在,1≤k≤BST总元素数1 \le k \le BST总元素数。2. 方法与思路  根据二叉搜索树的特点,中序遍历的结果即是排序好的数组。那么找出第k小的数,只需要先进行一次中序遍历即可。   /** * Definition for a binary tree node. * struct TreeNode {...
