更简单

#include<iostream>
using namespace std;
int main(){
    int arr[10*10*10*10*10*10*10+5]{};
    int n;
    cin>>n;
    for (int i = 1;i <= n;i++){
        cin>>arr[i];
    }
    int num[12]{};
    for (int i = 1;i <= n;i++){
        num[arr[i]]++;
    }
    for (int i = 1;i <= 10;i++){
        cout << i << "号歌手的选票为：" << num[i] << endl;
    }
    return 0;
}
