Description

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 a pair containing an iterator referring to the newly‐created entry and true. Use the specified hint as a starting point for checking to see if the key already in the unordered_map.
