Adjust the function autoCompleteAddress inside the src/server.ts file so it will return an array of Address objects. The goal is to return a list of unique addresses that the user can choose from.

Rules:

• All existing test pass
• You send a valid query to the BASE_URL and use it's response
• No TypeScript errors or warning in the code
• No other dependecies should be installed

Bonus: Only start this task when you are 100% sure the rest is absolutely perfect! Implement an addional function called autoCompleteAddressWithoutNo which returns the same but without the house numbers. Don't change the existing interfaces.

Build a Front End which allows the user to enter an address. The address needs to be 100% valid. Invalid street numbers, zip, city and street combinations need to show an error. Implement a better way for the user to select an address instead if typing everything himself. You are allowed to install anything that helps you build this including Frontend Frameworks, a style Library etc (except _).

Rules:

• All E2E tests pass (not yet here)
• think about a user-friendly way to create a page which let's anyone submit an address in cologne
• only accept valid addresses

Optional Hardcore-Mode: Don't use any framework or dependecies.
