A balanced binary tree is something that is used very commonly in analysis of computer science algorithms. In this lesson we cover how to determine the maximum number of items it can accommodate. We follow this with a discussion on the maximum height
1. We can make it to play trick in code. At Dialog's show function, after app has set contentView, we can add a GlobalLayoutListener on decorView's ViewTreeObserver. At the listener, we can check the decorView's height, if over the max height, just t
110.Balanced Binary Tree Given a binary tree, determine if it is height-balanced. For this problem, a height-balanced binary tree is defined as a binary tree in which the depth of the two subtrees of every node never differ by more than 1. 很早以前做的了 准
Given a binary tree, collect a tree's nodes as if you were doing this: Collect and remove all leaves, repeat until the tree is empty. Example:Given binary tree 1 / \ 2 3 / \ 4 5 Returns [4, 5, 3], [2], [1]. Explanation: Removing the leaves [4, 5, 3]
Given a binary tree, determine if it is height-balanced. For this problem, a height-balanced binary tree is defined as a binary tree in which the depth of the two subtrees of every node never differ by more than 1. Example Given binary tree A = {3,9,
Something to learn: Rotation ops in AVL tree does not require recursion. https://github.com/andreimaximov/hacker-rank/blob/master/data-structures/tree/self-balancing-tree/main.cpp node *create_node(int val) { node *pNew = new node; pNew->val = val; p
An AVL tree is a self-balancing binary search tree. In an AVL tree, the heights of the two child subtrees of any node differ by at most one; if at any time they differ by more than one, rebalancing is done to restore this property. Figures 1-4 illu
基础知识(包括但不限于:二叉查找树是啥,SBT又是啥反正又不能吃,平衡树怎么旋转,等等)在这里就不(lan)予(de)赘(duo)述(xie)了. 先贴代码(数组模拟): int seed; int _rand() { +; } template <class T> struct SbtNode { T val; int lSize; int rSize; int lch; int rch; void assignVir() { lSize=rSize=lch=rch=; } void ass
For a undirected graph with tree characteristics, we can choose any node as the root. The result graph is then a rooted tree. Among all possible rooted trees, those with minimum height are called minimum height trees (MHTs). Given such a graph, write
Print a binary tree in an m*n 2D string array following these rules: The row number m should be equal to the height of the given binary tree. The column number n should always be an odd number. The root node's value (in string format) should be put i

Overview AVL tree is a special binary search tree, by definition, any node, its left tree height and right tree height difference is not more than 1. The purpose of AVL tree is to try best to reduce the search time complexity. if the binary search tr
课程回顾 Swarthmore学院16年开的编译系统课,总共10次大作业.本随笔记录了相关的课堂笔记以及第2大次作业. 比较两个lists的逻辑: let rec cmp l ll = match (l,ll) with | [], [] -> 0 | [],_ -> -1 | _,[] -> 1 | (h::t), (hh::tt) -> if h > hh then 1 else if h < hh then -1 else cmp t tt;; 编程作业 1. 平
