Dfs and bfs in graph gfg

WebBreadth First Search is generally the best approach when the depth of the tree can vary, and you only need to search part of the tree for a solution. For example, finding the shortest path from a starting value to a final value is a good place to use BFS. ... like discovering the longest path between two nodes in an acyclic graph. Also DFS, can ... WebDFS of Graph. You are given a connected undirected graph. Perform a Depth First Traversal of the graph. Note: Use a recursive approach to find the DFS traversal of the …
