WebJan 17, 2024 · Step 1: call DFS traversal for the graph which can color the vertices. Step 2: If a partially visited vertex is found, backtrack till the vertex is reached again and mark all vertices in the path with a counter which is cycle number. Step 3: After completion of traversal, iterate for cyclic edge and push them into a separate adjacency list.
