std::forward_list::reverse(3)  C++ Standard Libary std::forward_list::reverse(3)

NAME
     std::forward_list::reverse - std::forward_list::reverse

Synopsis
	void reverse() noexcept;  (since C++11)

	Reverses  the  order  of the elements in the container. No references or
     iterators
	become invalidated.

Parameters
	(none)

Return value
	(none)

Complexity
	Linear in the size of the container.

Example
     // Run this code

      #include <iostream>
      #include <forward_list>

      std::ostream& operator<<(std::ostream& ostr, const std::forward_list<int>&
     list)
      {
	  for (auto& i : list)
	      ostr << ' ' << i;
	  return ostr;
      }

      int main()
      {
	  std::forward_list<int> list = {8, 7, 5, 9, 0, 1, 3, 2, 6, 4};
	  std::cout << "initially: " << list << '\n';

	  list.sort();
	  std::cout << "ascending: " << list << '\n';

	  list.reverse();
	  std::cout << "descending:" << list << '\n';
      }

Output:
      initially:  8 7 5 9 0 1 3 2 6 4
      ascending:  0 1 2 3 4 5 6 7 8 9
      descending: 9 8 7 6 5 4 3 2 1 0
