"WebFeb 13, 2024 · In this blog, we have discussed one of the methods to detect cycles in a directed graph. The idea is to do a DFS traversal of the graph and maintain an array of visited vertices. During the DFS traversal, if we find a back edge, i.e., an edge that connects back to an already visited verified, we will return the answer that the graph is cyclic. " - Dfs in python favtutor
