WebJan 2, 2024 · Practice. Video. Given a directed graph, check whether the graph contains a cycle or not. Your function should return true if the given graph contains at least one cycle, else return false. For example, the following graph contains three cycles 0->2->0, 0->1->2->0 and 3->3, so your function must return true. WebDec 16, 2024 · We have cyclic directed graph (possibly disconnected). For cycles consisting of two vertices A->B and B->A, we replace them by a single vertex. In case of A->B, B->C, C->A we also replace them by one vertex. We replace N vertices when all reachable from each other. Edges leaving a vertex stay as edges leaving the group …
