Trie is a tree data structure used to efficiently store and retrieve keys in a dataset of strings. There are various applications of this data structure, such as autocomplete and spellchecker. The Trie data structure is the classic data structure that is widely used in text searching. We need to implement Trie with the following method: Trie() and Trie.insert(). In the real example of Trie we had to introduce a small part of the data structure which consists of smaller pieces called **Tree. nodes.
