Description : list::rbegin() is an inbuilt function in C++ STL that returns a reverse iterator which points to the last element of the list.
Example :
std::list<int> lis = { 105, 207, 309, 401, 503 };
std::cout << "The list in reverse order: ";
for (auto it = lis.rbegin(); it != lis.rend(); ++it)
std::cout << *it << " ";
