WebMar 21, 2024 · We have also discussed a union-find algorithm for cycle detection in undirected graphs.. The time complexity of the union-find algorithm is O (ELogV). Like directed graphs, we can use DFS to detect a cycle in an undirected graph in O (V+E) time. We have discussed DFS based solution for cycle detection in an undirected graph . WebJun 16, 2024 · Topological Sorting. The topological sorting for a directed acyclic graph is the linear ordering of vertices. For every edge U-V of a directed graph, the vertex u will come before vertex v in the ordering. As we know that the source vertex will come after the destination vertex, so we need to use a stack to store previous elements.
