DFS - from recursion to iteration We implemented DFS using the simple recursive routine shown below (this version of DFS stores paths unlike the simpler version) private void dfs (Graph G, int v) { marked [V] = true; for (int w: G. adj (v)) { if (! marked[w]) { edge To[w] = v; dfs (G, W); } } } Rewrite this version w/o using recursion. private void dfs iterative (Graph G, int v) {
