WebMay 23, 2024 · Depth-first search (DFS) is a traversal algorithm used for both Tree and Graph data structures. The depth-first search goes deep in each branch before moving to explore another branch. In the next sections, we'll first have a look at the implementation for a Tree and then a Graph. To see how to implement these structures in Java, have a look … WebNov 18, 2024 · This is a Depth First Search (DFS) based algorithm to find all the articulation points in a graph. Given a graph, the algorithm first constructs a DFS tree. Initially, the algorithm chooses any random vertex to start the algorithm and marks its status as visited. The next step is to calculate the depth of the selected vertex.
