简单的set，struct，map使用。
`

include [HTML_REMOVED]

include [HTML_REMOVED]

include [HTML_REMOVED]

include [HTML_REMOVED]

include[HTML_REMOVED]

using namespace std;
int n,m;
struct a{
int flag;
set [HTML_REMOVED] s;
map[HTML_REMOVED] mp;
}a[110];

int main()
{
cin>>n>>m;

for(int i=1;i<=n;i++){
    cin>>a[i].flag;
    for(int j=1;j<=a[i].flag;j++){
        int shu;
        cin>>shu;
        a[i].mp[shu]++;//键值对
        a[i].s.insert(shu);
    }
}
        int find_shu[110]={0};
    int all_shu[110]={0};
for(int i=1;i<=n;i++){//篇

    for(int j=1;j<=m;j++){//找单词1，2，3
        if(a[i].s.find(j)!=a[i].s.end()) find_shu[j]++;
        all_shu[j]+=a[i].mp[j];
    }
}
for(int i=1;i<=m;i++){
    cout<<find_shu[i]<<" "<<all_shu[i]<<endl;
}
