Change maximum value of daily submissions. It is very easy to describe / implement the algorithm recursively:We start the search at one vertex.After visiting a vertex, we further perform a DFS for each adjacent vertex that we haven't visited before.This way we visit all vertices that are reachable from the starting vertex. : (. 1500. x20502.

Given an undirected graph, print all connected components line by line. The idea behind DFS is to go as deep into the graph as possible, and backtrack once you are at a vertex without any unvisited adjacent vertices.
