Dfs traversal using adjacency list
WebApr 10, 2024 · Define a function dfsTraversal that performs DFS traversal on the given graph, starting from a given vertex. This function takes three parameters −. graph − the adjacency list of the graph. vertex − the vertex from which DFS traversal should start. visited − an array of boolean values indicating whether a vertex has been visited or not WebThe applications of using the DFS algorithm are given as follows -. DFS algorithm can be used to implement the topological sorting. It can be used to find the paths between two vertices. It can also be used to detect cycles in the graph. DFS algorithm is also used for one solution puzzles. DFS is used to determine if a graph is bipartite or not.

WebApproach: Use Depth First Search. Mark all the nodes as unvisited and create and empty path and make the pathExist false. Start from the vertex v1 and visit the next vertex (use adjacency list). Keep track of visited nodes to avoid cycles. Add current vertex to result (taking integer array here) to keep track of path from vertex v1.
