    La salida de mi programa es igual a la esperada (verificadas con editores hex) pero el summit marca error.

    public static void main(String[] args) {

        String regex = "\\b(\\w+)\\s+\\1\\b";
        Pattern p = Pattern.compile(regex, Pattern.CASE_INSENSITIVE );

        Scanner in = new Scanner(System.in);
        int numSentences = Integer.parseInt(in.nextLine());
        
        while (numSentences-- > 0) {
            String input = in.nextLine();
            
            Matcher m = p.matcher(input);
            
            // Check for subsequences of input that match the compiled pattern
            while (m.find()) {
                String group = m.group();
                String[] temp = group.split(" ");
                input = input.replaceAll(group, temp[0]);
                m = p.matcher(input);
            }
            
            // Prints the modified sentence.
            System.out.println(input);
        }
        
        in.close();
    }
