WebApr 9, 2024 · We can use a path set to detect if there is a cycle in the graph and a visit set to detect if a node has been visited. Using the adj list, we can traverse the graph and update the colormap for each node using the colormap of its neighbors. Solution:-Create an adj list. Iterate through the edges and add the edges to the adj list.

In the following graph, It has a cycle 0-1-2-3-0 (1-2-3-4-1 is not cycle since edge direction is 1->4, not 4->1) Algorithm: …
WebAnd detect a cycle in the process DFS based algorithm: 1. Compute DFS(G) 2. If there is a back edgee = ( v, u) then G is not a DAG. Output cycle C formed by path from u to v in T plus edge (v, u). 3. Otherwise output nodes in decreasing post-visit order. Note: no need to sort, DFS (G) can output nodes in this order.
