#include <bits/stdc++.h>

using namespace std;

long long n,i,x,t1,t2,t3,k,dem;

int main()

{

cin>>n;

t1=0;

t2=0;

t3=0;

k=5;

dem=0;

for (i=1; i<=n; i++)

{

cin>>x;

if (x==k) dem++;

t1=t1+x;

if (x%2==0) t2+=x;

else t3+=x;

}

cout<<"Tong cua day la: "<<t1<<endl;

cout<<"Tong so chan la: "<<t2<<endl;

cout<<"Tong so le la: " <<t3<<endl;

cout<<"Trung binh cong la: "<<fixed<<setprecision(2)<<(t1*1.0)/(n*1.0)<<endl;

cout<<"So so hang bang k la: "<<dem;

return 0;
