"WebDepth-first search (DFS) is an algorithm for searching a graph or tree data structure. The algorithm starts at the root (top) node of a tree and goes as far as it can down a given branch (path), then backtracks until it finds an unexplored path, and then explores it. The algorithm does this until the entire graph has been explored. Many problems in computer … " - Dfs using recursion for graph

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.
