中序遍历(inorder traversal):左子树,当前结点,然后右子树 后序遍历(postorder traversal):左子树,右子树,然后当前结点 广度优先,第一层,第二层,第三层的所有结点 深度优先 删除 第一步要找到需要被删除的结点和它的父节点 第二步考虑如果被删除结点没有左子树的情况 第三步考虑被删除结点有左子树的情况 当要...
TreeNode root = charArrayToBST(arr); // 打印BST的中序遍历结果,即按顺序输出字符 inorderTraversal(root); } private static void inorderTraversal(TreeNode root) { if (root != null) { inorderTraversal(root.left); System.out.print(root.val + " "); inorderTraversal(root.right); } } }...

The tree is printed in the form of inorder traversal. BST Insertion Iterative To insert a Node iteratively in a BST tree, we will need to traverse the tree using two pointers. public static TreeNode insertionIterative(TreeNode root, int value) { ...
Given preorder and inorder traversal of a tree, construct the binary tree. 本题就是根据前序遍历和中序遍历的结果还原一个二叉树。 题意很简答,就是递归实现,直接参考代码吧。 查询index部分可以使用Map做查询,建议和下一道题 leetcode 106. Construct Binary Tree from Inorder and Postorder Traversal 中...

问使用常量内存对O(n)中的BST进行排序EN这是可能的，人们称它为作业，可能还没有尝试解决它。
Write a Python program to find the kth smallest element in a BST using in-order traversal and then return the element along with its rank. Write a Python script to implement a recursive function that returns the kth smallest element in a BST, handling edge cases where k is o...
