Insert into this map the specified value (in amortized constant time if the specified hint is a valid immediate successor to value) if a key (the first element) equivalent to that of value does not already exist in this map; otherwise, this method has no effect. Return an iterator referring to the (possibly newly inserted) value_type object in this map whose key is equivalent to that of value. If hint is not a valid immediate successor to value, this operation has O[log(N)] complexity, where N is the size of this map. This method requires that the (template parameter) types KEY and VALUE both be move-insertable into this map (see {Requirements on KEY and VALUE}). The behavior is undefined unless hint is an iterator in the range [begin() .. end()] (both endpoints included).
