What is breadth first search and depth-first search?
What is breadth first search and depth-first search?
BFS(Breadth First Search) uses Queue data structure for finding the shortest path. DFS(Depth First Search) uses Stack data structure. BFS can be used to find single source shortest path in an unweighted graph, because in BFS, we reach a vertex with minimum number of edges from a source vertex.
What is depth-first search Java?
Depth-first search (DFS) is a traversal algorithm used for both Tree and Graph data structures. The depth-first search goes deep in each branch before moving to explore another branch.
What is breadth first search in Java?
Breadth-first search (BFS) is an algorithm for searching a tree data structure for a node that satisfies a given property. It starts at the tree root and explores all nodes at the present depth prior to moving on to the nodes at the next depth level.
What is breadth first search BFS )? Explain with an example?
Breadth First Search (BFS) algorithm traverses a graph in a breadthward motion and uses a queue to remember to get the next vertex to start a search, when a dead end occurs in any iteration. As in the example given above, BFS algorithm traverses from A to B to E to F first then to C and G lastly to D.
What is depth first search with example?
Depth-first search (DFS) is an algorithm for traversing or searching tree or graph data structures. The algorithm starts at the root node (selecting some arbitrary node as the root node in the case of a graph) and explores as far as possible along each branch before backtracking.
Where is depth first search used?
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 find depth-first search?
Depth First Search (DFS)
- 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.
Which is better depth first or breadth first?
DFS, stands for Depth First Search. BFS uses Queue to find the shortest path. DFS uses Stack to find the shortest path. BFS is better when target is closer to Source.
What is the space complexity of depth first search?
Depth First Search has a time complexity of O(b^m), where b is the maximum branching factor of the search tree and m is the maximum depth of the state space. Terrible if m is much larger than d, but if search tree is “bushy”, may be much faster than Breadth First Search.
