统计字符串，用了map。

#include <stdio.h>#include <map>#include <string.h>#include <string>#include <iostream>using namespace std;map<string,int> s;int main(){ int n; while(scanf("%d",&n),n) { int len; string str; s.clear(); for(int i=0; i < n; i++ ) { cin >> str; s[str]++; } int max = -1; map<string,int>::iterator iter; for(iter = s.begin(); iter != s.end(); iter++) { if(iter->second > max) max = iter->second; } for(iter = s.begin(); iter != s.end(); iter++) { if(max == iter->second) cout<<iter->first<<endl; } } return 0;}
