红黑树(Red-Black Tree,以下简称RBTree)的实际应用非常广泛,比如Linux内核中的完全公平调度器、高精度计时器、ext3文件系统等等,各种语言的函数库如Java的TreeMap和TreeSet,C++ STL的map、multimap、multiset等。 RBTree也是函数式语言中最常用的持久数据结构之一,在计算几何中也有重要作用。值得一提的是,Java 8中Ha...
private void delete_red_leaf(TreeNode node, boolean needDel) 最后就是最麻烦的删除的删除黑色叶子(非Nil)节点的情况,找出兄弟节点,找出远侄子节点,找出近侄子节点。 private void delete_black_leaf(TreeNode node, boolean needDel) 删除叶子节点包含了另外一个参数booleanneedDel,因为上面提到的有些情况需要继续...
红黑树(Red Black Tree - RB Tree)就是这样一种数据结构,和很多数据结构一样,红黑树也有自己的一套事先规定好的规则,无论在什么状态下,一颗红黑树都必须满足以下五个规则(定义), 破坏任何一条规则都不再是一颗红黑树。 1. 红黑树的节点不是红色的就是黑色的 ...
红黑树(Red-Black Tree)也是一种自平衡二叉查找树,在前面的文当中,我们已经描述了AVL树了。AVL树与红黑树很像,因此也经常被放到一起比较。 与其他平衡二叉树不同,红黑树的每个节点有个额外的位来存储节点的颜色(红色或者黑色)。这些颜色位保证了在树的插入和删除时能保持平衡。
First choice for BST is a Red-Black tree as it is most universal data structure. However if your tree will be used mostly for search then take a look at AVL tree. If mostly the same elements are retrieved again and again then Splay tree can be even better. If sometimes there is a ...
