I would rather put const std::map<K,V>& map as a parameter, that is a const ref. It won't change the code but can greatly help the compiler to optimize the code.

i think auto is better than typename std::map<K, V>::iterator iter;

addressing comment: iterator doesn't work with const argument here. Code works fine in snippet, though I'm passing by ref.

@AntonBrunyee, of course it is not working, because you need a const_iterator over iterator.
