The std::map::rbegin() is a function in C++ STL. It returns a reverse iterator which points to the last element of the map. The reverse iterator iterates in reverse order and incrementing it means moving towards beginning of map.
r_i rbegin(); const_r_i rbegin() const;
Parameters: It does not except any parameters.
Returns: It returns a reverse iterator which points to the last element of the map.
Time Complexity: O(1)
Below examples illustrate the map::rbegin() method:
Map contains following elements in reverse order e = 5 d = 4 c = 3 b = 2 a = 1
Map contains following elements in reverse order e = E d = D c = C b = B a = A
