使用Trie树,将单词放入空的Trie树中,然后遍历字符数组,递归查找,每当找到Trie树的单词节点(可以组成一个单词的节点),就将单词放入数组中,最后返回该数组即可。 实现如下: Trie树的构造方式: classTrieNode{public:intcount;//该节点代表的单词的个数,由此判断当前节点是否构成一个单词vector<TrieNode*> children;//...

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...
