# What to do if there's not much space for improvement on a question? [duplicate]

I've been coming over this question

unordered_multimap approach to adjacency list and graph search

I'm looking for suggestions on how to improve the usage of modern C++ features with this simple graph search algorithm, particularly with regard to the use of STL containers and lambda expressions.

As far as I can see that's all done fine, and I have no idea how to improve that further.

Does that deserve an answer like

Your code is fine don't worry

Maybe with some additional note, that it's good to use auto keywords and lambda expressions?

How should such question be handled?
