hdu1004――Let the Balloon Rise

 

原题：

Problem Description

Contest time again! How excited it is to see balloons floating around. But to tell you a secret, the judges' favorite time is guessing the most popular problem. When the contest is over, they will count the balloons of each color and find the result.

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

 

Input

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

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

 

Output

For each case, 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.

 

Sample Input

   
   
   
   

    
    
    
    5 green red blue red red 3 pink orange pink 0 
   
   
   
   

 

Sample Output

   
   
   
   

    
    
    
    red pink
   
   
   
   

分析：

统计出现在最多的字符串；water~~~~~~输入n个用户喜欢的各种颜色，输出最受欢迎的颜色
