NumberFormat Parse and Reformat

Read a comma-formatted number string, parse it back to a numeric value with NumberFormat, then reprint it with exactly 2 decimal places.

Use sc.nextLine() to read the string, then NumberFormat.getNumberInstance(Locale.US).parse(text) to convert it. parse() returns a Number object - call .doubleValue() to get a double. The method throws ParseException so main needs throws Exception.

⚠️ AUTO-INPUT MODE: The input stream will automatically contain '12,345.6\n'. Use sc.nextLine() to read it.

Expected Output:

Parsed: 12345.60↵

= newline. The output ends with a newline — print one after the last line.
