A trie, also known as a prefix tree, is a tree-like data structure that is used to efficiently store and retrieve strings or sequences of characters. It is particularly useful for tasks such as searching for words in a dictionary or implementing autocomplete functionality. In a trie, each node represents a single character, and the edges represent the next possible characters in the sequence. The nodes are typically organized in a hierarchical manner, with each level representing a different character position in the string. This allows for fast searching and retrieval of strings, as well as efficient prefix matching.
