vector<int> inorderTraversal(TreeNode* root) { vector<int> vec; if(root == NULL)return vec; inorder(root,vec); return vec; } }; 递归 class Solution { public: void inorder(TreeNode* root, vector<int> & vec) { if(root -> left != NULL) { inorder(root -> left,vec); } vec...
1. Pre-order Traversal(前序遍历): 也就是先访问根节点,然后访问左叶子节点与右叶子节点 2. In-order Traversal(中序遍历):先访问左叶子节点,接着访问根节点,最后访问右叶子节点 3. Post-order Traversal (后序遍历):先访问左叶子节点,再访问右叶子节点,最后访问根节点 值得注意的是当你删除树的某一个节点...
代码长度限制 16000 B 判题程序 Standard 作者 CHEN, Yue Suppose that all the keys in a binary tree are distinct positive integers. Given the postorder and inorder traversal sequences, you are supposed to output the level order traversal sequence of the corresponding binary tree. Input Specification...
in the tree has not been completed. In this case the descent is simply rolled back and retried a short while later. We say that the tree traversal operation “gives up” at this point, and repeats the entire descent, giving the ongoing split some time to be posted in the parent (or ...
Leetcode 144. 二叉树的前序遍历【简单】 给你二叉树的根节点 root ,返回它节点值的 前序 遍历。 中序遍历(Inorder Traversal) 从根节点开始,首先按照中序遍历的方式访问左子树,然后访问根节点,最后访问右子树。中序遍历通常用于访问二叉搜索树中的节点,以升序或降序访问节点值。
