TrieNode Class: Represents individual nodes with
childrenandisEndOfWordattributes and core methods:addChild: Adds a child node for the given character and returns the child node.getChild: Retrieves the child node for the given character, or null if no such child exists.hasChild: Checks if a child node for the given character exists.Trie Class: Implements core methods:
insert: Inserts a word into the Trie.search: Searches for a word in the Trie.startsWith: Finds words starting with a given prefix.delete: Deletes a word from the Trie and recursively removes nodes associated with a word.getWords(): Retrieves all words in the Trie.traverseTrieNode: Recursively collect all words starting from a given node.Unit Tests:
TrieTest.phpincludesPHPUnittests to validate the correct behavior of insertion, search, deletion, and retrieval functions.GitHub Actions
All tests and workflows (in my forked repository) have passed.
