WebMar 12, 2024 · Pre-order, in-order and post-order traversals are DFS -based algorithms. In contrast to them, level-order traversal is based on BFS. Level-order traversal maintains a pool of current nodes. Initially, the pool contains only the root node. At each step, we iterate over the nodes in the pool and collect their children. WebFeb 18, 2024 · In other words, we call dfs_visit in the number of degree of the vertex inside dfs_visit. In the worst case, we should call dfs_visit in the number of all the vertices times.
