浅谈算法和数据结构: 九平衡查找树之红黑树

定义红黑树的主要是像是对2-3查找树进行编码，尤其是对2-3查找树中的3-nodes节点添加额外的信息。红黑树中将节点之间的链接分为两种不同类型，红色链接，他用来链接两个2-nodes节点来表示一个3-nodes节点。黑色链接用来链接普通的2-3节点。特别的，使用红色链接的两个2-nodes来表示...

浅谈算法和数据结构: 九平衡查找树之红黑树

原文:浅谈算法和数据结构: 九平衡查找树之红黑树前面一篇文章介绍了2-3查找树，可以看到，2-3查找树能保证在插入元素之后能保持树的平衡状态，最坏情况下即所有的子节点都是2-node，树的高度为lgN，从而保证了最坏情况下的时间复杂度。但是2-3树实现起来比较复杂，本文介绍一种简单实现2-3树的...

浅谈算法和数据结构: 十平衡查找树之B树

原文:浅谈算法和数据结构: 十平衡查找树之B树前面讲解了平衡查找树中的2-3树以及其实现红黑树。2-3树种，一个节点最多有2个key，而红黑树则使用染色的方式来标识这两个key。维基百科对B树的定义为“在计算机科学中，B树（B-tree）是一种树状数据结构，它能够存储数据、对其进行排序并允许以...

浅谈算法和数据结构: 八平衡查找树之2-3树

原文:浅谈算法和数据结构: 八平衡查找树之2-3树前面介绍了二叉查找树(Binary Search Tree)，他对于大多数情况下的查找和插入在效率上来说是没有问题的，但是他在最差的情况下效率比较低。本文及后面文章介绍的平衡查找树的数据结构能够保证在最差的情况下也能达到lgN的效率，要实现这一目...
