今天我们来介绍另一种平衡二叉树:红黑树(Red Black Tree),红黑树由Rudolf Bayer于1972年发明,当时被称为平衡二叉B树(symmetric binary B-trees),1978年被Leonidas J. Guibas和Robert Sedgewick改成一个比较摩登的名字:红黑树。 红黑树和之前所讲的AVL树类似,都是在进行插入和删除操作时通过特定操作保持二叉查找树的...

RedBlackTree 其它数据结构: 树:二叉树 二叉搜索树 AVL树 链表:链表 双链表 简介 红黑树,由红黑两色结点组成的二叉搜索树,并且满足以下条件: 1.树根始终为黑色 2.外部结点均为黑色 3.其余结点若为红色,则其孩子结点必为黑色 4.从任一外部结点到根结点的沿途,黑结点的数目相等 数据结构 红黑树结点的颜色 enum...
c-rbtree Intrusive Red-Black Tree Collection The c-rbtree project implements an intrusive collection based on red-black trees in ISO-C11. Its API guarantees the user full control over its data-structures, and rather limits itself to just the tree-specific rebalancing and coloring operations. For...
PAT 1135 Is It A Red-Black Tree 【C++版】 1.题意 给出一个先序序列,判断由这个先序序列得到的红黑树是否是一棵红黑树。其中红黑树需满足的定义如下: (1) Every node is either red or black. (2) The root is black. (3) Every leaf (NULL) is black. ...
【数据结构】什么是红黑树(Red Black Tree)? 📌红黑树的概念 我们之前学过了二叉搜索树和平衡二叉搜索(AVL)树, 除了它们, 还有一个被广泛运用的平衡二叉搜索树是红黑树(RB-Tree)。 红黑树是一种平衡二叉搜索树的变体, 它的左右子树高差有可能大于 1,所以红黑树不是严格意义上的平衡二叉搜索树(AVL),但对之...
Each set of sibling objects in one level of the containment hierarchy (all child objects under a storage object) is represented as a red-black tree. The parent object of this set of siblings will have a pointer to the top of this tree.A...
