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

Sample Output

red

pink

字符串的比较：两个数组color[1005][16]和num[1005]。数组color是用来保存颜色的，数组num是用来保存颜色出现的次数，最后求出数组num中最大的数的下标即为出现次数最多的颜色。

 #include <iostream>
 #include <cstdio>
 #include <cstring>
 using namespace std;
 char color[][];
 int num[];
 int main()
 {
     int n, i, j, max;
     while(scanf("%d",&n) && n)
     {
         for (i=; i<n; i++)
             scanf("%s",&color[i]);
         for(i=; i<; i++)
             num[i] = ;
         for(i=; i<n; i++)
             for(j=; j<i; j++)
                 if(strcmp(color[i],color[j])==)
                     num[i]++;
         max = ;
         j = ;
         for(i=; i<n; i++)
             if (max<num[i])
             {
                 max = num[i];
                 j = i;
             }
         printf("%s\n",color[j]);
     }
     return ;
