BFS vs DFS for Binary Tree - GeeksforGeeks

The result of a depth-first search of a graph can be conveniently described in terms of a spanning tree of the vertices reached during the search. Based on this spanning tree, the edges of the original graph can be divided into three classes: forward edges, which point from a node of the tree to one of its descendants, back edges, which point from a node to one of its ancestors, and cross edges… WebApr 12, 2024 · Suppose you had an infinitely large general/non-binary to search. Because the tree is infinitely large, an exhaustive DFS or BFS strategy is not feasible. However, a DFS search with parameter, depth=n, is highly desirable.
