平衡二叉搜索树(Balanced BST): 了解 AVL 树和红黑树 (Red-Black Tree) 的概念。不要求能够手写实现这些复杂的平衡树,但需要理解它们为什么能够通过自平衡操作(如旋转)来保证树的高度大致为 logN,从而确保各种操作的时间复杂度维持在 O(logN) 水平 1。java.util.TreeMap 和 java.util.TreeSet 底层就是用红黑树...
If you know advanced data structures like Trie, B-Tree, AVL tree, then it’s well and good. But, if you don’t know, then I suggest you join a comprehensive course like Data Structures and Algorithms: Deep Dive Using Java, which will teach you everything about all those fundamentals. ...
AVL tree One of the oldest, most well known and most popular tree data structure. It saves additional height information in each node and re balances tree if height of one node is higher than its sibling by 2. That keeps tree rigidly balanced so search is extremely fast on AVL tree. How...

平衡二叉树也叫平衡二叉搜索树(Self-balancing binary search tree)又被称为 AVL 树, 可以保证查询效率较高。具有以下特点:它是一 棵空树或它的左右两个子树的高度差的绝对值不超过 1,并且左右两个子树都是一棵平衡二叉树。平衡二叉树的常用实现方法有红黑树、AVL、替罪羊树、Treap、伸展树等。举例说明, 看看下...

TreeMap和LinkedHashMap是有序的(TreeMap默认升序,LinkedHashMap则记录了插入顺序)。 参照:http://uule.iteye.com/blog/1522291 请你简单说下HashMap的Put()方法. 抽象类和接口的区别,类可以继承多个类么,接口可以继承多个接口么,类可以实现多个接口么。
Self-balancing binary search tree AVL trees In practice: From what I can tell, these aren't used much in practice, but I could see where they would be: The AVL tree is another structure supporting O(log n) search, insertion, and removal. It is more rigidly balanced than red–black ...
An adjacency matrix is a way of representing a graph as a matrix of booleans. In this tutorial, you will understand the working of adjacency matrix with working code in C, C++, Java, and Python.
TreeSet底层是TreeMap,TreeMap是基于红黑树来实现的。 如果想实现一个线程安全的队列,可以怎么实现? 知道LRU 吗,20分钟基于 HashMap 实现一个 LRU 算法,面试官给个地址,进去写代码,面试官远程看 如何设计实现一个LRU Cache? 二叉树的遍历方式,前序、中序、后序和层序 ...
