WebJan 12, 2024 · Due to the fact that many things can be represented as graphs, graph traversal has become a common task, especially used in data science and machine learning. Graph Theory and Graph-Related … WebWhat is the cost of recursive DFS for a graph with v vertices and e edges? The function dfs creates an array of marks with all positions initialized to zero (i.e., to false) on line30. This takes O(v) time. The call to free is constant time. Therefore, the asymptotic complexity of dfs is equal to the cost of the call to dfs_helper on line31. ion washing machine
