WebA Depth–first search (DFS) is a way of traversing graphs closely related to the preorder traversal of a tree. Following is the recursive implementation of preorder traversal: procedure preorder (treeNode v) { visit (v); for each child u of v preorder (u); } To turn this into a graph traversal algorithm, replace “child” with “neighbor”. WebSince we examine the edges incident on a vertex only when we visit from it, each edge is examined at most twice, once for each of the vertices it's incident on. Thus, breadth-first …
