DefinedDictionary tree, also known as the word search tree, Trie tree, is a tree structure, the typical application is used for statistics, sorting and saving a large number of strings, so often used by the search engine system for text word frequency statistics. Its advantages are: the use of the common prefix of the string to save storage space, the maximum reduction of meaningless string comparisons, query efficiency than hash table high.ExplainThi
