    Scanner sc = new Scanner(System.in);
    int group = sc.nextInt();

    for(int i = 0;i < group;i++){
        int tableNum = sc.nextInt();
        String table = sc.next();
        int eaters = sc.nextInt();
        String eatGenger = sc.next();

        char[] gender = eatGenger.toCharArray();
