试题分析：本题如果使用预定义的map类会非常的方便

#include<iostream>
#include<map>
#include<string>

using namespace std;

int n,maxNum;
string a;
string maxColor;
map<string,int> ballon;
int main()
{

    while(cin>>n)
    {

        if(!n)break;
        maxNum = 0;
        ballon.clear();
        
       for(int i=0;i<n;i++){
