If a key equivalent to the specified `key` already exists in this unordered_map, assign the specified `obj` to the value associated with that key, and return an iterator referring to the existing item. Otherwise, insert into this map a newly‐created `value_type` object, constructed from `(std::forward<KEY>(key), std::forward<BDE_OTHER_TYPE>(obj)...))`, and return an iterator referring to the newly‐created entry. Use the specified `hint` as a starting point for checking to see if the key already in the unordered_map.
