By introducing a zero length path into the pattern, we have been able to instruct Cypher to bind the lastPost and post variables to the very same node in the zero length path case. These examples are extracted from open source projects. Now that we are somewhat familiar with the two shortest path commands, the shortest path, or a single path and the all shortest paths command or multiple shortest paths, we're going to use that in a little bit of a creative way to return the diameter of the graph.
