HDU 1004 Let the Balloon Rise

Problem Description

Contest timeagain! How excited it is to see balloons floating around. But to tell you asecret, the judges' favorite time is guessing the most popular problem. Whenthe contest is over, they will count the balloons of each color and find theresult.

This year, they decide to leave this lovely job to you. 

Input

Inputcontains multiple test cases. Each test case starts with a number N (0 < N<= 1000) -- the total number of balloons distributed. The next N linescontain one color each. The color of a balloon is a string of up to 15lower-case letters.

A test case with N = 0 terminates the input and this test case is not to beprocessed. 

Output

For eachcase, print the color of balloon for the most popular problem on a single line.It is guaranteed that there is a unique solution for each test case.
