#include <vector>
#include <list>
#include <memory>
#include <exception>
int main() {
    std::unique_ptr<std::vector<int>>  kk;
        try {
                kk.reset(new std::vector<int>(2));
                std::list<int> ll(kk->begin(), kk->end());
                std::reverse(ll.begin(), ll.end());
