平衡二叉树也叫自平衡二叉搜索树(Self-Balancing Binary Search Tree),所以其本质也是一颗二叉搜索树,不过为了限制左右子树的高度差,避免出现倾斜树等偏向于线性结构演化的情况,所以对二叉搜索树中每个节点的左右子树作了限制,左右子树的高度差称之为平衡因子,树中每个节点的平衡因子绝对值不大于1,此时二叉搜索树称之为...

上面这棵Trie树包含的字符串集合是{in, inn, int, tea, ten, to}。每个节点的编号是我们为了描述方便加上去的。树中的每一条边上都标识有一个字符。这些字符可以是任意一个字符集中的字符。比如对于都是小写字母的字符串,字符集就是’a’-‘z’;对于都是数字的字符串,字符集就是’0’-‘9’;对于二进制...
