Write a program that reads a single word (string) from the user using Scanner and prints:

Hello, [name]!

Use scanner.next() to read the string. Note: next() reads only until the first space.

⚠️ IMPORTANT - AUTO-INPUT MODE:
This question uses automated input testing. When you run your code, the input stream will AUTOMATICALLY contain: 'Alice\n'

DO NOT wait for manual keyboard input - Scanner will read from the pre-filled buffer stream immediately. Your program should use Scanner methods like next() or nextLine() to read these values directly.

Think of it like Eclipse/VS Code but with the input already typed in and waiting for your Scanner to read it.
