Solution: Total Number of Words in a Trie

To determine the total number of words in a trie, the algorithm traverses the trie structure starting from the root node and counts the nodes that mark the end of a word. This is achieved through a recursive exploration of child nodes, ensuring efficient access based on common prefixes. The time complexity is O(n), where n is the total number of nodes, while the space complexity is O(m), with m representing the total number of characters across all words.
