Input

public class StringProblem {

 public static void main(String[] args) {

        Scanner sc = new Scanner(System.in);

        int test = sc.nextInt();

        sc.nextLine();

        while (test-- > 0) {

            TreeSet<Character> set = new TreeSet<>();

            for (int i = 0; i < str.length(); i++) {

                set.add(str.charAt(i));

            }

            int lower = 0, upper = 0;

            for (char ch : set) {

                if (('a'==ch)||('e' == ch)||('i'==ch)||('o'==ch)||('u'==ch)){

                    lower++;

                }else if(('A' == ch)||('E'== ch)||('I' == ch)||('O'==ch)||('U'==ch)) {

                    upper++;

                }

            }

            if ((upper >= 5) || (lower >= 5)) {

                System.out.println("lovely string");

            } else {

                System.out.println("ugly string");

            }

        }
