The Penn Vet Wоrking Dоg center mаintаins а grоwing database of registered working dogs. Each dog has a unique name made up of lowercase English letters ('a' to 'z'). To support fast lookup and name-based querying, they use a Trie data structure to store all the dog names. The system supports the following operations: 1. Insert a new dog name into the Trie. 2. Check whether a dog name is already registered. 3. Find all registered dog names that begin with a given prefix. Assume there are n unique dog names in the database, and each name has a length between 1 and m. Answer the following using Big-O notation: a. What is the maximum depth of the Trie? [depth] b. What is the worst-case time complexity for checking if a dog name exists in the Trie? [time] c. What is the worst-case time complexity of retrieving all dog names that start with a given prefix of length k, assuming there are r such names and the average length of the r retrieved dog names is l? [autocomplete-time]
