解题思路:

注意事项:

参考代码:

#include <iostream>

using namespace std;

int main()

{

    int k,sum1=0,sum2=0,sum3=0;

    cin>>k;

    for(int i=1; i<=k; i++)

    {

        int a;

        cin>>a;

        if(a==1)

        {

            sum1++;

        }

        else if(a==5)

        {

            sum2++;

        }

        else if(a==10)

        {

            sum3++;

        }

    }

    cout <<sum1<< endl;

    cout <<sum2<< endl;

    cout <<sum3<< endl;

    return 0;

}
