std::multiset emplace_hint() method
- od C++11
// Non const version only
template <class... Args>
iterator emplace_hint( const_iterator hint, Args&&... args );
Inserts a new element to the container as close as possible to the position just before hint.
The element is constructed in-place, i.e. no copy or move operations are performed.
The constructor of the element is called with exactly the same arguments as supplied to the function, forwarded with std::forward<Args>(args)....

Parameters

Amortized constant if the new element is inserted just before hint - O(1).
Exceptions
If an exception is thrown by any operation, this function has no effect (strong exception guarantee).
