Tries Data Structure Overview
A trie (derived from retrieval) is a multiway tree data structure used for storing strings over an alphabet. It is used to store a large amount of strings. The pattern matching can be done efficiently using tries.
Different operations in Tries:-
Advantages of Using Tries
- In tries the keys are searched using common prefixes. Hence it is faster. The lookup of keys depends upon the height in case of binary search tree.
- Tries take less space when they contain a large number of short strings. As nodes are shared between the keys.
- Tries help with longest prefix matching, when we want to find the key.
