Voting for Photos
题目描述
After celebrating the midcourse the students of one of the faculties of the Berland State University decided to conduct a vote for the best photo. They published the photos in the social network and agreed on the rules to choose a winner: the photo which gets most likes wins. If multiple photoes get most likes, the winner is the photo that gets this number first.
Help guys determine the winner photo by the records of likes.
The first line of the input contains a single integer n (1≤n≤1000) − the total likes to the published photoes.
The second line contains n positive integers a1,a2,...,an (1≤ai≤1000000), where ai is the identifier of the photo which got the i-th like.
Print the identifier of the photo which won the elections.

In the first test sample the photo with id 1 got two likes (first and fifth), photo with id 2 got two likes (third and fourth), and photo with id 3 got one like (second).
Thus, the winner is the photo with identifier 2, as it got:
- more likes than the photo with id 3;
- as many likes as the photo with id 1, but the photo with the identifier 2 got its second like earlier.
