In a novel execution model, all data sources are tries. Two or more input tries are combined in accordance with the respective set operation, to obtain the set of keys associated with the nodes of a respective resulting trie. An intersection operation performed in this way can be used for ...
Since this data structure is a prefix tree,trieis commonly used in Dictionaries, Phone Directories and matching algorithms.Trieis best-suited for phone directory (any matching application for that matter) because it is very efficient in matching strings. 因为这个数据结构是一个前缀树,Trie通常被用在...
The array is much faster in most cases, But sometimes the array need a huge space in comparison with the pointer approach, Look at this problem on SpojLink You may get MemoryLimitExceeded if you solve this problem using array in some online judges. ...

Trie, also called digital tree and sometimes radix tree or prefix tree (as they can be searched by prefixes), is a kind of search tree—an ordered tree data structure that is used to store a dynamic set or associative array where the keys are usually strings. It is one of those data-...
