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. WebFeb 20, 2024 · Complexity Of Depth-First Search Algorithm. Depth-First Search or DFS algorithm is a recursive algorithm that uses the backtracking principle.
