Given n, how many structurally unique BST's (binary search trees) that store values 1 ... n? Example: 这道题实际上是 卡塔兰数 Catalan Numbe 的一个例子,如果对卡 ...
Given an integern, generate all structurally uniqueBST s binary search trees that store values ...n. Example: 这道题是之前的Unique Binary Search Trees的延伸,之前那个只要求算出所有不同的二叉搜索树的个数,这道题让把那些二叉树都建立出来。这种建树问题一般来说都是用 ...

BST's. 题意:给定数n,二叉树的结点的值分别为1,2....n。问能组成多少种不同的二叉搜索树 ...
Medium! 题目描述: 给定一个整数 n,生成所有由 1 ... n 为节点所组成的二叉搜索树。 示例: 解题思路: 这种建树问题一般来说都是用递归来解,这道题也不例外,划分左右子树,递归构造。至于递归函数中为啥都用的是指针,是参考了http ...
