Hello, everybody,

at the moment I am really lost. The problem is to create the color map that
can be used in Depth_First_Search. A special feature that I have is that I
want to change the Vertex color of DFS to modify the DFS. For example like

If I make the color map global and pass it to the visitor, everything works:

If the color map is not global but external, I can write the map, but it is
not the same as the DFS color map and therefore I cannot manipulate the DFS

I then tried to create an internal map and work with the get() and put()
functions, but I didn't succeed:

I'd be so grateful if you'd give me a hint.
