Zoo Management System

This problem requires you to implement a simple Zoo Management System. The system should maintain information about animals where each animal is identified by its unique name and has associated attributes: species, age, and gender. You will receive a series of commands to manipulate the Zoo database. The operations include adding a new animal, retrieving the details of an animal, updating the animal's information, removing an animal from the system, and listing all animals in lexicographical order. Note that the sorting can be mathematically described as \(\text{sorted}(names)\) where the names are ordered in ascending order.

inputFormat

The first line of input is an integer \(n\) representing the number of commands. Each of the following \(n\) lines contains one command. The commands follow one of these formats:

• ADD name species age gender - Adds a new animal. If an animal with the same name already exists, output False, otherwise output True.
• GET name - Retrieves animal details in the order: species age gender. If the animal does not exist, output None.
• UPDATE name species age gender - Updates the information of an existing animal. If a field should remain unchanged, a dash (-) is used in its place. Output True if the update is successful; otherwise, output False if the animal does not exist.
• REMOVE name - Removes an animal identified by name. Outputs True if removal is successful, otherwise False.
• LIST - Prints all animal names sorted in lexicographical order separated by a space. If there are no animals, print an empty line.

outputFormat

For each command that produces an output (ADD, GET, UPDATE, REMOVE, LIST), print the result on a new line. The output should exactly match the expected values, including booleans and text.
