WebAnswer: The question needs more details. The following points may be considered before reframing. * Time complexity is a term associated with the time taken by an Algorithm … WebStart by putting one of the vertexes of the graph on the stack's top. Put the top item of the stack and add it to the visited vertex list. Create a list of all the adjacent nodes of the vertex and then add those nodes to the unvisited at the top of the stack. Keep repeating steps 2 and 3, and the stack becomes empty.

WebMar 10, 2024 · So the complexity of BFS is V + E. Pseudocode for BFS: create a queue Q . v.visited = true. Q.push(v) while Q is non-empty remove the head u of Q mark and enqueue all (unvisited) neighbours of u. Since we are only iterating over the graph’s edges and vertices only once, hence the time complexity for both the algorithms is linear O(V+E).
