WebIf your dfs detects a cycle, then all the cycle vertices are the type that's in the stack (they must have been visited, but they cannot be finished because you will find a cycle before finishing any vertex on it). So, one easy way to find the cycle is to maintain the stack along with a dfs (vector or stack, either global or passed by reference).
