WebSep 11, 2024 · So, to detect a cycle in an undirected graph, we can use the same idea. The algorithm would be: For each edge in the edge list: Find parents(set name) of the source and destination nodes respectively (Though we are using terms like source & destination node, the edges are undirected). WebIt employs the following rules. Rule 1 − Visit the adjacent unvisited vertex. Mark it as visited. Display it. Push it in a stack. Rule 2 − If no adjacent vertex is found, pop up a vertex from the stack. (It will pop up all the vertices from the stack, which do not have adjacent vertices.) Rule 3 − Repeat Rule 1 and Rule 2 until the stack ...
