Trie
A Trie (prefix tree) is a tree-like data structure used to store a dynamic set of strings, where each node represents a single character. Words that share common prefixes share the same path from the root, making prefix-based lookups extremely efficient. Tries are fundamental to autocomplete systems and spell checkers.
Use Cases
- •Autocomplete and type-ahead suggestions
- •Spell checking and word validation
- •IP routing and longest prefix matching
