map 小用法

#include <cstdio>#include <cstring>#include <map>#include <algorithm>using namespace std;int main(){int n,a;while(scanf("%d",&n)==1){int maxx=-1;map<int ,int >q;while(n--){scanf("%d",&a);            q[a]++;            if(q[a]>maxx){            maxx=q[a];            }}printf("%d\n",maxx);}}
