FBI树的后序遍历：C++代码实现

{/'title/': /'FBI树的后序遍历：C++代码实现/', /'description/': /'本文介绍了一种名为FBI树的二叉树，并提供C++代码实现，用于构建FBI树并输出其后序遍历序列。FBI树的节点类型分为三种：B节点（全“0”串）、I节点（全“1”串）和F节点（既含“0”又含“1”的串）。/', /'keywords/': /'FBI树, 后序遍历, C++代码, 二叉树, 数据结构, 算法/', /'content/': /'#include ///'iostream///'//n#include ///'string///'//nusing namespace std;//n//nstruct Node{//n char type;//n Node* left;//n Node* right;//n};//n//nNode* buildTree(string s){//n int n = s.length();//n if(n == 1){//n Node* node = new Node();//n if(s[0] == '0'){//n node->type = 'B';//n }else{//n node->type = 'I';//n }//n node->left = nullptr;//n node->right = nullptr;//n return node;//n }//n //n int mid = n/2;//n string s1 = s.substr(0, mid);//n string s2 = s.substr(mid, n-mid);//n //n Node* node = new Node();//n node->type = 'F';//n node->left = buildTree(s1);//n node->right = buildTree(s2);//n //n return node;//n}//n//nvoid postOrderTraversal(Node* root){//n if(root == nullptr){//n return;//n }//n //n postOrderTraversal(root->left);//n postOrderTraversal(root->right);//n cout << root->type;//n}//n//nint main(){//n int n;//n cin >> n;//n string s;//n cin >> s;//n //n Node* root = buildTree(s);//n postOrderTraversal(root);//n //n return 0;//n}/
