Trie is a tree-like data structure used to store strings. The tries are also called prefix trees because they provide very efficient prefix-matching operations. Implement a trie data structure with three functions that perform the following tasks:
Insert (word): This inserts a word into the trie.
Search (word): This searches the given word in the trie and returns TRUE if the complete word is found (i.e., all characters match and the last node is marked as the end of a word). Otherwise, return FALSE.
Search prefix (prefix): This searches the given prefix in the trie and returns TRUE if the prefix path exists in the trie (i.e., all prefix characters match), regardless of whether the last node is marked as the end of a word. Otherwise, return FALSE.
Constraints:
word.length, prefix.length ≤500There are multiple data structures that can be used to store strings. However, for a majority of them, searching a string requires a complete traversal of the stored data. A more efficient approach is to use a trie.
A trie is a tree of characters. The trie takes a word as a parameter and creates a new node for each character of that word. This way, the given string is searched character by character and does not require an exhaustive search. Therefore, this problem fits perfectly in the trie pattern.
