Check if a directed graph is connected or not - GeeksforGeeks
WebMar 13, 2024 · The task is to check if the given graph is connected or not. Examples: Input: Output: Yes Input: Output: No Recommended: Please try your approach on {IDE} first, before moving on to the solution. Approach: Take two bool arrays vis1 and vis2 of size N (number of nodes of a graph) and keep false in all indexes. WebDec 16, 2024 · While you could indeed use DFS to find the connected components, SciPy makes it even easier with scipy.sparse.csgraph.connected_components.

Key Lemma: Consider two “adjacent” strongly connected components of a graph G: components C1 and C2 such that there is an arc (i,j) of G with i ∈ C1 and j ∈ C2. Let f(v) denote the finishing time of vertex v in some execution of DFS-Loop on the reversed ... WebAug 26, 2014 · There, the components variable happens to be the last component in the graph (it's the last thing assigned to that loop variable), and you're printing out your total component count and time, which is the total component count and time for all components because of Issue #2. Here's something that should work. body mesin cuci lg
