public class Main {
    public static void main(String[] args) {
        List<String> text = List.of(
                "Hello #Moscow",
                "Hello #SaintPetersburg",
                "#SaintPetersburg has good #Weather",
                "#Moscow has bad #Weather",
                "#Moscow has #Rain"
        );

        System.out.println(getTags(text));
        System.out.println(getTagsByPopularity(text));
    }

    private static List<String> getTags(List<String> text) {
        // collect all unique tags ignoring case and sort them alphabetically
        return
    }

    private static List<String> getTagsByPopularity(List<String> text) {
        // collect all unique tags ignoring case and sort them by popularity
        return
    }
