WebMar 28, 2024 · A cycle in graph theory is a path that originates at one vertex and terminates at the same vertex. A significant field of computer science research is cycle detection. Finding a cycle in an undirected graph is extremely difficult. It's complexity is Omega (n). Let us understand this concept with an example. 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.
