WebMar 19, 2024 · To implement the DFS we use stack and array data structure. There are two cases in the algorithm: Whenever we visit a vertex we mark it visited and push its adjacent non-visited vertices into the stack and pop the current vertex from the stack. If all the adjacent vertices are visited then only pop the current vertex from the stack. WebAug 18, 2012 · Viewed 3k times. 1.
