WebHere we need to find the path from vertex 0 to 3. The input format is : Number of Vertices in the graph, Number of edges. Vertices between which we need to find the path. In inner for loop you don't check if q is not … WebRecommended: Please try your approach on {IDE} first, before moving on to the solution. In normal BFS of a graph, all edges have equal weight but in 0-1 BFS some edges may have 0 weight and some may have 1 weight. In this, we will not use a bool array to mark visited nodes but at each step, we will check for the optimal distance condition.
