WebBFS and DFS are two simple but useful graph traversal algorithms. In this article, we will introduce how these two algorithms work and their properties. BFS. The central idea of breath-first search is to search “wide” before search “deep” in a graph. In other words, BFS visits all the neighbors of a node before visiting the neighbors of ... WebGiven a directed acyclic graph ( DAG) of n nodes labeled from 0 to n - 1, find all possible paths from node 0 to node n - 1 and return them in any order. The graph is given as follows: graph [i] is a list of all nodes you can visit from node i (i.e., there is a directed edge from node i to node graph [i] [j] ).

"WebA depth first search on a directed graph can yield 4 types of edges; tree, forward, back and cross edges. As we are looking at undirected graphs, it should be obvious that forward and back edges are the same thing, so the only things left to deal with are cross edges. " - Get the dfs of the graph
