Trie Implementation
Detailed guide and Python implementation for the 'Trie Implementation' problem.
Problem Statement
Write a function run_trie_operations(commands, arguments) that simulates Trie operations. The function takes a list of command strings and a list of argument lists, executing them in order and returning a list of the execution results. The commands are:
- 'Trie': Initialize a Trie (returns None)
- 'insert': Inserts a string into the Trie (returns None)
- 'search': Returns True if the string is in the Trie, else False
- 'startsWith': Returns True if there is any word in the Trie that starts with the given prefix, else False.
- •1 <= len(commands) <= 1000
- •1 <= len(arguments[i]) <= 1
- •All words and prefixes consist of lowercase English letters.
Examples
run_trie_operations(['Trie', 'insert', 'search', 'startsWith', 'insert', 'search'], [[], ['apple'], ['apple'], ['app'], ['app'], ['app']])
[None, None, True, True, None, True]
1. Initialize Trie -> None 2. Insert 'apple' -> None 3. Search 'apple' -> True 4. StartsWith 'app' -> True 5. Insert 'app' -> None 6. Search 'app' -> True
