NumberFormat Integer Grouping

Use NumberFormat.getIntegerInstance() to read a large integer and print it with comma grouping separators.

Expected Output:
Grouped: 1,000,000

getIntegerInstance(Locale.US) creates a formatter that inserts commas every 3 digits from the right. Read the number with nextLong() or nextInt(), then pass it to nf.format().

⚠️ AUTO-INPUT MODE: The input stream will automatically contain '1000000\n'. Use Scanner's nextLong() or nextInt() to read it.

Expected Output:

Grouped: 1,000,000
