Back edge: It is an edge (u, v) such that v is the ancestor of node u but is not part of the DFS tree. Edge from 6 to 2 is a back edge. Presence of back edge indicates a cycle in directed graph . Cross Edge: It is an edge that connects two nodes such that they do not have any ancestor and a …

I can see why you would think that. For n=5 (say a,b,c,d,e) there are in fact n! unique permutations of those letters. However, the number of cycles of a graph is different from the number of permutations in a string, because of duplicates -- there are many different permutations that generate the same identical cycle.. There are two forms of duplicates:Spanning tree has n-1 edges, where n is the number of nodes (vertices). From a complete graph, by removing maximum e - n + 1 edges, we can construct a spanning tree.
