#include <iostream>#include <list>#include <algorithm>using namespace std;template <class T>void print(T  &t){cout<<t;}template <class T>class  Print{public:void operator()(T&t)   {   cout<<t;   }}; int main(){list <int>  L;for (int i=1;i <=7;i++)   L.push_front(i);for_each(L.begin(),L.end(),print<int> );cout<<endl;for_each(L.begin(),L.end(),Print<int>() );return 1;}
