即按照左 -> 根 -> 右的顺序, 先访问子节点(叶子), 然后再访问根节点, 最后右侧节点. 同样节点访问处理可以传递一个通用的回调函数 callback, 同时用一个辅助方法inOrderTraverseNode(node, callback)来接受一个节点和回调函数. // 辅助方法: 节点遍历inOrderTraverseNode(node, callback) {// 基本情况if(...

Three numbers in a BST that adds upto zero 给定一个平衡二叉搜索树 (BST),编写一个函数 isTripletPresent(),如果给定 BST 中有一个三元组且总和等于 0,则返回 true,否则返回 false。预期时间复杂度为 O(n^2),只能使用 O(Logn) 额外空间。您可以修改给定的二叉搜索树。请注意,平衡 BST 的高度始终为 O...
I am beginner at Coldfusion. I remade an entire website that was also coded in Coldfusion. As I am not an expert, I took some of the existing code to make the new website. The new one works all good, ... Is there anyway to avoid repetitive class instantiations for all methods in ...

450. Delete Node in a BST Given a root node reference of a BST and a key, delete the node with the given key in the BST. Return the root node reference (possibly updated) of the BST. Basically, the deletion can be divided into two stages: ...
PAT 甲级 1115 Counting Nodes in a BST (30 分) BST DFS 技术标签: PAT\蓝桥杯刷题原题链接:1115 Counting Nodes in a BST (30 分)题目大意:这个题中的BST和之前的BST的定义有点不一样,所以要看清楚题目的条件。 本题将一系列数字按顺序插入到一个空的二叉搜索树中,然后,请你计算结果树的最低两层...
