WebDFS prefers to visit undiscovered vertices immediately, so the search trees tend to be deeper rather than balanced as with BFS. Notice that the DFS consists of three ``Hamiltonian'' paths, one in each component -- while the BFS tree has far more degree-3 nodes, reflecting balance.

WebAug 10, 2024 · Approach: DFS is a traversal technique which involves the idea of recursion and backtracking. DFS goes in-depth, i.e., traverses all nodes by going ahead, and when there are no further nodes to traverse in the current path, then it backtracks on the same path and traverses other unvisited nodes. In DFS, we start with a node ‘v’, mark it as ...
