Detect cycle in graph using dsu
WebJul 1, 2024 · Method 1 (Using BFS) : In this method we are going to use Breadth First Search or BFS to find cycle in a graph. In dfs for each vertex v we iterate through all its adjacent vertices and for each vertex a and mark it visited, further make v the parent of a (so that parent is not considered for cycle). If there is any vertex a which is already ... Web2) It is used to determine the cycles in the graph. In the Kruskal’s Algorithm , Union Find Data Structure is used as a subroutine to find the cycles in the graph, which helps in finding the minimum spanning tree.(Spanning tree …
