WebSince both the vertices belong to the same set; therefore, there is a cycle. We have detected a cycle, so we will consider the edges further. How can we detect a cycle with the help of an array? Consider the below graph: The above graph contains the 8 vertices. So, we represent all these 8 vertices in a single array.

WebApr 11, 2024 · So Union-find algo will give wrong results for directed graphs. No, we cannot use union-find to detect cycles in a directed graph. This is because a directed graph … 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 ... porsche carrera t zwart
