How to write the code of C++ to realize binary search tree?

Most people do not understand the knowledge points of this article "how to write the code for C++ to achieve a binary search tree", so the editor summarizes the following contents for you. The content is detailed, the steps are clear, and it has a certain reference value. I hope you can get something after reading this article. Let's take a look at this "C++ to achieve binary search tree code how to write" article.

The specific code is as follows:

Class BST {public: value Node* left; Node* right; int N of the key int value;// node of the struct Node {key node / number of leaf nodes of the node Node (int _ key, int _ value, int _ N) {key = _ key; value = _ value; N = _ N;}; BST (); ~ BST (); void put (int key, int value) Int get (int key); int deleteKey (int key); private: Node* _ deleteKey (int key, Node* x); Node* _ deleteMin (Node* x); int size (Node* x); int _ get (int key, Node* x); Node* _ put (int key, int value,Node * x); Node* min (Node* x); Node* root;}; inline int BST::size (Node* x) {if (x = nullptr) return 0; return x-> N } int BST::_get (int key, Node * x) {if (x = = nullptr) return 0; if (x-> key)

< key)_get(key, x->

Right); else if (x-> key > key) _ get (key, x-> left); else {return x-> value;} return 0;} BST::Node* BST::_put (int key, int value, Node* x) {if (x = = nullptr) {Node* tmp = new Node (key, value, 1); return tmp;} if (x-> key > key) {x-> left=_put (key, value, x-> left);} else if (x-> key)

< key) { x->

Right=_put (key, value, x-> right);} else x-> key = key; x-> N = size (x-> left) + size (x-> right) + 1; return x;} BST::Node* BST::min (Node* x) {if (x-> left = = nullptr) return x; return min (x-> left);} BST::BST () {} BST::~BST () {} void BST::put (int key, int value) {root=_put (key, value, root) } int BST::get (int key) {return _ get (key, root);} BST::Node* BST::_deleteKey (int key, Node* x) {if (x-> key > key) x-> left = _ deleteKey (key, x-> left); else if (x-> key)

< key)x->

Right = _ deleteKey (key, x-> right); else {if (x-> left = = nullptr) return x-> right; else if (x-> right = = nullptr) return x-> left; else {Node * tmp = x; x = min (tmp- > right); x-> left = tmp- > left; x-> right = _ deleteMin (tmp- > right);} x-> N = size (x-> left) + size (x-> right) + 1; return x } BST::Node* BST::_deleteMin (Node* x) {if (x-> left = = nullptr) return x-> right; x-> left = _ deleteMin (x-> left); x-> N = size (x-> left) + size (x-> right) + 1; return x;} int BST::deleteKey (int key) {return _ get (key, root) } the above is about the content of this article, "how to write the code for C++ to achieve a binary search tree".
