可以看出,Trie树的关键字一般都是字符串,而且Trie树把每个关键字保存在一条路径上,而不是一个结点中。另外,两个有公共前缀的关键字,在Trie树中前缀部分的路径相同,所以Trie树又叫做前缀树(Prefix Tree)。 解题方法 本文写成前缀树入门教程。 从二叉树说起 ...
trie(pronounced as "try") or prefix tree is a tree data structure used to efficiently store and retrieve keys in a dataset of strings. There are various applications of this data structure, such as autocomplete and spellchecker. Implement the Trie class: ...
Trie (我们读作“try”)或prefix tree是一种树形数据结构,它被用作检索字符串数据集的密钥。这有关于这个高效的数据结构的不同应用: 1 . 自动补全 2 . 拼写检查 3 . IP路由 4 . T9文字输入法 5 . 解决单词游戏 这里有很多别的数据结构,比如说平衡树和哈希表,它们都可以给我们在字符串数据集中搜索一个...
