Binary Tree Puzzles and Interview Questions Many of the "programming puzzle of the day", or "dev job interview questions" relate to binary trees. This repo contains a binary tree implementation in a Go package, as well as code that solves puzzle-or-problem-of-the-day questions....
Given an integer arraynumswhere the elements are sorted inascending order, convertit to aheight-balancedbinary search tree. Example 1: Input:nums = [-10,-3,0,5,9]Output:[0,-3,9,-10,null,5]Explanation:[0,-10,5,null,-3,null,9] is also accepted: Example 2: Input:nums = [1,3]...
给你一个含重复值的二叉搜索树(BST)的根节点root,找出并返回 BST 中的所有众数(即,出现频率最高的元素)。 如果树中有不止一个众数,可以按任意顺序返回。 假定BST 满足如下定义: 结点左子树中所含节点的值小于等于当前节点的值 结点右子树中所含节点的值大于等于当前节点的值 ...
The solution of the iterator applies to a lot of related questions. So make sure you practise this question until you are perfect. You WILL BE ASKED this question at times. You could read my other post[Question] Iterator of Binary Search Tree. Solution We only need to keep 1 variable in...
314. Binary Tree Vertical Order Traversal https://leetcode.com/problems/binary-tree-vertical-order-traversal/#/description Given a binary tree, return the vertical order traversal of its nodes' values. (ie, from top to bottom, column by column). If two nodes are in the same row and ...

Input:root = [4,2,7,1,3], val = 5Output:[] Constraints: The number of nodes in the tree is in the range[1, 5000]. 1 <= Node.val <= 107 rootis a binary search tree. 1 <= val <= 107 FindTabBarSize FindBorderBarSize
Given a binary tree, find the lowest common ancestor (LCA) of two given nodes in the tree. According to thedefinition of LCA on Wikipedia: “The lowest common ancestor is defined between two nodespandqas the lowest node inTthat has bothpandqas descendants (where we allowa node to be a ...

Maximum Depth of Binary Tree Given a binary tree, find its maximum depth. The maximum depth is the number of nodes along the longest path from the root node down to the farthest leaf node. Solution - Recursion The recursion algorithm is easy to come up: ...
