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...
6.红黑树中黑色节点的右孩子一定是黑色的(如果右孩子为空,那么它是黑色的;如果右孩子不为空,所连接的节点要么是3节点,要么是2节点,均是根节点,也就是黑色的) RedBlackTree.java(红黑树) //红黑树 public class RedBlackTree<K extends Comparable<K>, V> { private static final boolean RED = true; pri...
简介 红黑树又名Red Black Tree(RBT),是一种自平衡二叉查找树,RBT中的每个节点都有颜色,要么是红色要么是黑色。有以下性质: 根节点是黑色 叶子节点都是不存储数据的黑色空节点 红色节点的儿子节点都是黑色 任何一个节点到其所有叶子节点路径上的黑色节点数都相同 注意: 性质2中的叶子节点是只为空(NIL或null)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。

To improve the performance, when the number of nodes reaches a threshold (default is 8), the LinkedList is converted to RedBlack Tree. When the number of nodes decreases below a threshold (default 6), the tree is converted back to LinkedList. You can read this article to understand the ...
