WebMar 12, 2011 · 0. Using Stack, here are the steps to follow: Push the first vertex on the stack then, If possible, visit an adjacent unvisited vertex, mark it, and push it on the stack. If you can’t follow step 1, then, if possible, pop a vertex off the stack. If you can’t follow step 1 or step 2, you’re done. WebThe time complexities for BFS and DFS are just O ( E ), or in your case, O (m). In a binary tree, m is equal to n-1 so the time complexity is equivalent to O ( V ). m refers to the total number of edges, not the average number of adjacent edges per vertex. Yes, O (n) is correct. Also note that the number of edges can more exactly be expressed ...
