https://leetcode.com/problems/balanced-binary-tree/ 题意分析: 判断一棵树是不是平衡树。 题目思路: 如果左子树高度和右子树高度差小于等于1,并且左子树是平衡树,右子树是平衡树,那么这棵树是平衡树。那么我们先用一个新的函数返回树的高度和是否平衡树。 代码(python): View Code...
AVL 树2-3查找树伸展树红黑树B树（也写成B-树，B-tree，中间的“-”代表杠）B+ 树 AVL 树 也叫平衡二叉树（Balanced Binary Tree），AVL是提出这种数据结构的数学家。概念是对于所有结点，BF 的绝对值小于等于1，即左、右子树的高度之差的绝对值小于等于1 在各种平衡查找树当中，AVL 树和 2-3 树已经成为...

Python Exercises, Practice and Solution: Write a Python program to create a Balanced Binary Search Tree (BST) using an array of elements where array elements are sorted in ascending order.
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. 题目分析: 平衡二叉树:(1)要么为空,要么左右子树的深度差值不超过1;(2)左右两个子树都是一棵平衡二叉树,即子树也都要都满足条件(1...

GoLLRB is a Left-Leaning Red-Black (LLRB) implementation of 2-3 balanced binary search trees in Go Language. Overview As of this writing and to the best of the author's knowledge, Go still does not have a balanced binary search tree (BBST) data structure. These data structures are quite...
