    for (const auto& elem : coll)
    {
        std::cout << elem << "  ";
    }
    std::cout << std::endl;
}

#include <iostream>
#include <list>
#include <algorithm>
#include <iterator>

#include "myprint.hpp"
using namespace std;

    list<int> list1;
    for (int k = 1; k <= 9;++k) 
    {
        list1.push_back(k);
    }

    PRINT_ELEMENTS(list1);

    iter_swap(list1.begin(),next(list1.begin()));
    PRINT_ELEMENTS(list1);

    iter_swap(list1.begin(),prev(list1.end()));
