Fgt ein neues Element in den Behlter mit
hint als Anregung, wo das Element gehen sollte. Das Element in-place ist so aufgebaut, dh kein Kopieren oder Verschieben von Operationen durchgefhrt werden. 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)....Original:
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.

If the insertion failed because the element already exists, returns an iterator to the already existing element with the equivalent key.
