Create a `value_type` object for each iterator in the range starting at the specified `first` iterator and ending immediately before the specified `last` iterator, by converting from the object referred to by each iterator. Insert into this unordered map each such object whose key is not already contained. The (template parameter) type `INPUT_ITERATOR` shall meet the requirements of an input iterator defined in the C++11 standard [24.2.3]providing access to values of a type convertible to `value_type`. The behavior is undefined unless `first` and `last` refer to a sequence of valid values where `first` is at a position at or before `last`. Note that this method requires that the (template parameter) types `KEY` and `VALUE` both be `copy‐constructible` (see {Requirements on `value_type`}).
