Depth-first search (DFS):

“Depth-first search” is an algorithm used for traversing tree or graph. In graph, the search will start from any vertex V. But in tree, the search will starts form the root.

  • DFS of a graph will start at any vertex V, and then recursively visits remaining vertices, which is adjacent to that vertex V.
  • DFS of a tree will visit the root first, and then recursively visits the subtrees of the root R.
  • It searches “deeper” in the graph, because graph may contain cycles. Hence it is referred as “depth-first” search.
