WebThe following is Exercise 22.3-6 from CLRS (Introduction to Algorithms, the 3rd edition; Page 611). Show that in an undirected graph, classifying an edge $(u,v)$ as a tree edge or a back edge according to whether $(u,v)$ or $(v,u)$ is encountered first during the depth-first search is equivalent to classifying it according to the ordering of the four types in the … WebDFS Time Complexity- The total running time for Depth First Search is θ (V+E).
