std::{{{1}}}::emplace_hint

من cppreference.com
template <class... Args>
iterator emplace_hint( const_iterator hint, Args&&... args );
(since C++11)

Inserts a new element to the container, using ‎hint‎ as a suggestion where the element should go. The element is constructed in-place, i.e. no copy or move operations are performed. The constructor of the element type (‎value_type‎, that is, std::pair<const Key, T>) is called with exactly the same arguments as supplied to the function, forwarded with std::forward<Args>(args)....
