Dfs on adjacency list

WebWhen you encounter an edge that has its two endpoints already assigned the same color, you can terminate the algorithm and conclude that the input graph is not 2-colorable. a. (15 points) Programming. Implement in Java an algorithm using DFS to determine whether an input graph is 2-colorable. Please use adjacency lists to represent the input graph. 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.
