Two fork Sorting tree introduction
We know that the binary tree, each node has a maximum of 2 Shang trees, known as the Saozi right subtree.The binary sort tree, apparently also a binary tree, has a more salient feature that renders sorting on the data field .In the two-fork sort tree , the data field of the left subtree of each tree is less than its root node value, and the data field of the right subtree
Each node of a binary tree has a maximum of two Shang trees (no node with a degree greater than 2), and the subtree of the binary tree has a left and right part, and the order cannot be reversed. The first layer of the binary tree has at most 2^{i-1} nodes, and the two-forked tree with a depth of K has at most 2^k-1 nodes; for any binary tree T, if its terminal node number is N_0, and the number of degrees 2 is n_2, then n_0=n_2+1.
A tree with a depth of K, and a 2^k-1 node called full two

Topic
Given the head node of a binary tree, it is known that the values of all the nodes are not the same, find the two fork tree with the most nodes in the search, and return the head node of this subtree.
For example
Max search subtree as right
Analytical
First of all to explain what is the largest search subtree, is the binary search tree, the value of any node must be greater than the maximum number
the data type of the given binary tree is as follows
typedef char Element;
struct Node
{
Element data;
struct Node *lchild;
struct Node *rchild;
typedef struct NODE Btnode;
typedef struct NODE * BTREE;
Two fork tree creation IComplete the Btree create_btree (char s[]) function, the function creates a binary tree from the string s, where the string s is represented by a generalized table of two-forked trees consisting only of ' (', ', ') '
How to get the order of the two-fork tree by the pre-sequence and the middle order of the two-fork tree?First of all, we must understand what is pre-order, middle order, sequence.Binary Tree Pre-order: The traversal sequence is, the root node, the Zuozi, the right subtree; middle order: The traversal order is, the Zuozi, the root node, the right sub-tree; Post order: Traversal sequence is, Zuozi, right subt

This is a tower defense game, the map is a n numbered 1~n node of the tree, node 1 is the enemy base, the other leaf nodes are your base.
The enemy base will continue to come out of the monster, in order to prevent the enemy from attacking your base, you can choose to build towers.
Each node can only build one tower, and the node I may have the Ki species tower for you to choose from, the price and attack the Price_i, respectively, Power_i

meet the above requirements: when we find the ownership of the current new node from top to bottom, we will split the full node along the way, then we can guarantee that whenever we want to split aFull node y, make sure its parents are not full. It can be seen that the only way the tree grows tall is to split the root node.First, create a new node Z and then the original y node of t ... 2t-1 (t-1) to the new node Z, and then put the middle keyword in yThe parent node.Insert the keyword into the

It's annoying to have this kind of error because you don't know which file is causing the entire project error. So we can open the error button below and see what the problem is.If this is because Java compiler level does is not match the version of the installed Java,So we open the project's properties and have an option for project facets,Click Open, select Java version on the right to the latest, then apply, should be OK.It is also possible that the referenced jar package is invalid and can b

problem : Print the binary tree from top to bottom, and the nodes in the same layer are printed to one line from left to right. For example:
Print results:
8
6 10
5 7 9 11
Analysis: In order to print each row of the two-fork tree to a single line, we need two variables: One variable represents the number of nodes that have not been printed in the current layer, and the other represents the next level of nodes.
