Read Double with Printf Display

Write a program that reads a double from the user and displays it with exactly 4 decimal places:

You entered [number]

Example: If user enters 3.14, output should be: You entered 3.1400

Use scanner.nextDouble() to read input and System.out.printf() with %.4f to format the output.

⚠️ IMPORTANT - AUTO-INPUT MODE:
This question uses automated input testing. When you run your code, the input stream will AUTOMATICALLY contain: '3.14\n'

DO NOT wait for manual keyboard input - Scanner will read from the pre-filled buffer stream immediately. Your program should use scanner.nextDouble() to read the value.

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