22110_AcademyAwards

Selected from 3,850 teams from 1,329 universities in 68 countries competing at 106 sites and preliminary contests worldwide, sixty-eight teams competed for bragging rights and prizes at The 27th Annual ACM International Collegiate Programming Contest World Finals sponsored by IBM on March 25, 2003, in Hollywood, California. The 2003 World Champion is Warsaw University. And Zhongshan University won the 8th place. During those days, another world famous event was held in the same place. It was the 75th Annual Academy Awards. It's also known as Oscar.

We always say that the Best Picture is the most important award of all the awards. Before the Oscar Night, we can't tell which film will win Best Picture. Fortunately, we can dope it out from the Nominee List of all the awards other than the Best Picture. I suggest that you should follow my 3 rules here.

• All the films in the list have chances to win the Best Picture

• The film which will win the Best Picture is the film which has been nominated the most tunes in the list

• If there are more than one film which have been nominated the most times in the list, we will choose the first one which appears in the list

Let's see such a List below.

ROAD TO PERDITION

From the list, we can find that THE LORD OF THE RINGS: THE TWO TOWERS has been nominated twice. And each of the other films has been nominated only once. So we can say THE LORD OF THE RINGS: THE TWO TOWERS will win the Best Picture.

Your task is to write a program to figure out the anticipatory winner from the list.

The input file will consist of several lists. The first line of each list contains only one integer n (1 ≤ n ≤ 100), representing the number of awards in the list. Then you get n blocks. Each block indicated the nominees of a distinct award. The first line of each block is the name of the award which is not longer than 80. The second line is m_i (1 ≤ m_i ≤ 10, 1 ≤ i ≤ n) -- the number of nominated films. In the following lines are m_i film names, one per line. For make the question simple, you can assume that there isn't any space in the film names.

The input is terminated by a line with one zero.

For each list, you are supposed to figure out the winner of Best Picture in a single line.
