What is DFS application?
Depth-first search is used in topological sorting, scheduling problems, cycle detection in graphs, and solving puzzles with only one solution, such as a maze or a sudoku puzzle. Other applications involve analyzing networks, for example, testing if a graph is bipartite.
How do I apply for DFS?
The DFS algorithm works as follows:
- Start by putting any one of the graph’s vertices on top of a stack.
- Take the top item of the stack and add it to the visited list.
- Create a list of that vertex’s adjacent nodes.
- Keep repeating steps 2 and 3 until the stack is empty.
What is depth first search (DFS)?
Depth-first search (DFS) is an algorithm (or technique) for traversing a graph. Following are the problems that use DFS as a building block. 1) For an unweighted graph, DFS traversal of the graph produces the minimum spanning tree and all pair shortest path tree. A graph has cycle if and only if we see a back edge during DFS.

What is the use of BFS (breadth first search)?
Like DFS, the BFS (Breadth First Search) is also used in different situations. These are like below − In peer-to-peer network like bit-torrent, BFS is used to find all neighbor nodes Search engine crawlers are used BFS to build index. Starting from source page, it finds all links in it to get new pages
What is the use of BFS algorithm?
Using GPS navigation system BFS is used to find neighboring places. In networking, when we want to broadcast some packets, we use the BFS algorithm. Path finding algorithm is based on BFS or DFS. BFS is used in Ford-Fulkerson algorithm to find maximum flow in a network.
