The Penn Vet Working Dog center maintains a growing 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]

In the Marvel show Moon Knight Marc frequently experiences blackouts and wakes up in unfamiliar places with no memory of what happened. He sometimes speaks and behaves as entirely different people, including a British man named Steven and a ruthless vigilante named Jake. Marc’s symptoms are most consistent with:

You have been give three data definition classes, Home, NewBuild, and FixerUpper.  NewBuild and FixerUpper extend the Home superclass. All three classes are concrete classes. Your client states that they need to be able to calcuate the minimum deposit amount for each home type. You decide that a method should be added in the Home superclass that will force the FixUpper and NewBuild subclasses to overwrite it. In Java, write the appropriate method called depositNeeded for the Home superclass. The depositNeeded method should return a double. Also, using course terminology, explain any other changes in the Home class that would be needed in order for the Home class to successfully compile.
