Graph – Depth First Traversal (DFS) in JAVA | Algorithms

Given a graph, do the depth first traversal(DFS). What is depth-first traversal– Depth-first search (DFS) is an algorithm for traversing or searching tree or graph data structures. One starts at the root (selecting some arbitrary node as the root in the case of a graph) and explores as far as possible along each branch before backtracking.
