    String regex = "(?iu)\b(\w+)\b(?:\s+\1\b)+"; Pattern p = Pattern.compile(regex);

        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()) {
            input = input.replaceAll(regex, "$1");
        }

        // Prints the modified sentence.
        System.out.println(input);
    }

    in.close();
