I have a directed graph. Is the following a cycle? Do the arrows have a specific direction in a cycle?
解决方案
It is not a directed cycle. However, if you permit consideration of the underlying undirected graph (by forgetting the orientations of the edges), then there is an undirected cycle. It all depends on which category you're interested in!

No, it isn't a cycle. Remember that a cycle is a closed path. Then the final vertex match with the initial vertex. Here you don't have a closed path...
