直接上map

统计数字

其实觉得set也可以过....
```c++
#include <iostream>
#include <cstdio>
#include <map>
using namespace std;

map<int, int> used;

int main()
{
int n, a;

cin >> n;
while(n --)
{
scanf("%d", &a);
used[a] ++;
}

for(map<int, int>::iterator it = used.begin();it != used.end();it ++)
cout << it -> first << ' ' << it -> second << endl;

return 0;
}
```

#include<cstdio>
#include<cstring>
#include<iostream>
#include<algorithm>
#include<map>
using namespace std;
typedef long long ll;
map<int,int> s;
int main()
{
    int n,x,i;
    scanf("%d",&n);
    for(i=1;i<=n;i++)
    {
        scanf("%d",&x);
        s[x]++;
    }
    for(auto x:s)
        printf("%d %d\n",x.first,x.second);
    return 0;
}

set怎么过。。难道是multiset

  我大multiset大法好 #滑稽
