Unique Binary Search Trees: To generate the number of two-fork sort trees.Given N, how many structurally unique BST's (binary search trees) that store values 1 ... n?For example,Given N = 3, there is a total of 5 unique BST ' s. 1 3 3 2 1 \// /\ 3 2 1 1 3 2
only once. The trick of Method 3 is to limit the range of node values in the subtree so that each node is accessed only once. The initial range of node values can be limited to int_min and Int_max.Determine if the BSTBOOL Isbst (node* Node){Return (Isbstutil (node, int_min, Int_max));}Returns true if it is a binary lookup tree with a value range of [Min,max]BOOL Isbstutil (node* Node, int min, int max)Code
Binary search tree:1. Each node has a key code (key) as a search basis, the key code is different.2. All key codes of the left subtree are smaller than the key code of the root node.3. All key codes of the right subtree are greater than the key code of the root node.4. The left and right sub-trees are two-fork
Given A binary search tree (BST), find the lowest common ancestor (LCA) of the Given nodes in the BST.According to the definition of the LCA in Wikipedia: "The lowest common ancestor is defined between," nodes V and W as the L Owest node in T, have both V and W as descendants (where we allow a node to be a descendant of itself).

Corresponding to Chapter 12th of Introduction to algorithms. Compared with a common Binary Tree, BST meets the unique condition: the Key of any node> the key of the left child, and the key of the right child.1. node class:

child of the precursor node is empty, set its right child to the current node. The current node is updated to the left child of the current node. b) If the right child of the precursor node is the current node, reset its right child to null. The reverse output is from the left child of the current node to all nodes on this path of the precursor node .The current node is updated to the right child of the current node. 3. Repeat the above 1, 2 until the current node is empty.Analysis of Complex

OverviewThis chapter first introduces the relevant theoretical knowledge of two-fork tree, then gives the detailed implementation of C language. On the learning of binary tree, it is necessary to explain: it is not difficult, not only not difficult, but it is very simple. The first contact with the tree, I also think i
Problem Description:Enter a binary search tree and now convert the two-fork search tree into a sorted doubly linked list. And in the process of conversion, you cannot create any new nodes, only the point of the node pointer in the tree
