The idea is to have two references to the list and move them at different speeds. Move one forward by 1 node and the other by 2 nodes.
If the linked list has a loop they
will definitely meet.
Else either of
the two references(...
How can I make git ignore future revisions to a file?
...e this, preferably with a script executed whenever you pull or clone. One idea would be that anything with a particular extension (say .basefile) gets copied to a file with the extension dropped and then the file name gets added to .gitignore in that directory.

How to store Node.js deployment settings/configuration files?
