What is a Trie primarily used for?

• Encrypting data

• Sorting data

• Searching for entries that match a prefix string

• Storing large datasets

Which operation is NOT typically associated with Tries?

• Find Prefix

• Delete

• Find Word

• Insert

What does the 'word' variable in a Trie node indicate?

• The number of children nodes

• The total number of words in the Trie

• Whether a word ends at that node

• The character stored in the node

In the context of Tries, what does the term 'n-ary tree' refer to?

• A tree with a fixed number of children

• A tree where each node can have multiple children

• A tree that only stores integers

• A binary tree structure

What is the first step in the insert operation of a Trie?

• Traverse through the existing nodes

• Create a new node for each character

• Set the current node as a word

• Check if the string is empty

How does the find operation in a Trie differ from the insert operation?

• It sets the word variable to 1

• It requires a different data structure

• It creates new nodes

• It returns false if a character is not found

What is the purpose of the findPrefix function?

• To list all possible words with a certain prefix

• To locate a word in the Trie

• To delete a word from the Trie

• To insert a new word into the Trie

What does the 'newnode' function do in the context of Tries?

• It deletes a node from the Trie

• It creates a new Trie node

• It finds a word in the Trie

• It initializes the Trie structure

Which of the following is an application of Tries?

• Database indexing

• Image processing

• Google autocomplete feature

• Data compression

What character is associated with the root node of a Trie?

• The null character

• The last character of the last word
