Types

type Trie

type Trie struct {
	// contains filtered or unexported fields
}

Trie 是便于 word 插入与查找的数据结构

func Constructor

func Constructor() Trie

func (*Trie) Insert

func (this *Trie) Insert(word string)

func (*Trie) Search

func (this *Trie) Search(word string) bool

func (*Trie) StartsWith

func (this *Trie) StartsWith(prefix string) bool
