前缀表达树(Trie, Prefix Tree)又称单词查找树是一种多叉树结构, 前缀表达式的主要思路是,根节点开始 根节点不包含字符, 除根节点外每一个子节点都包含一个字符,将从根到某一节点的 字符连接起来形成对应的字符串, 最后在节点中设置一个标记,标记该节点之前的路径是否构成一个单词, 从而实现单词查找。 前缀表达...

红黑树是一种更加实用的非严格的平衡二叉树。红黑树更关注局部平衡而非整体平衡,确保没有一条路径会比其他路径长出 2 倍,所以是接近平衡的,但减少了许多不必要的旋转操作,更加实用。前面提到过,Java 8 的 HashMap 中就应用了红黑树来解决散列冲突时的查找问题。TreeMap 也是通过红黑树来保证有序性的。
