    Has anyone faced the problem that code does not print to stdout even though it does in local machine? here is my code

            try (Scanner aScanner = new Scanner(System.in)){
            int num = aScanner.nextInt();
            List<String> linesAfterDeduplication = new LinkedList<>();
            for (int i = 0; i <= num; i++) {
                String line = aScanner.nextLine().trim();
                Matcher matcher = pattern.matcher(line);
                while (matcher.find()) {
                    line = line.replace(matcher.group(0), matcher.group(1));
                }
                linesAfterDeduplication.add(line);
            }

            for (String line : linesAfterDeduplication) {
                System.out.println(line);
            }
        }
